How To Choose The Best 7.2 Volt Battery

Before you click buy, you need to match three things: the chemistry, the connector, and the physical size. A battery with the right voltage but the wrong plug simply will not connect to your device.

The Connector Is The Gatekeeper

Most RC cars use a Tamiya plug, while security panels use a prong-style connector. Check the battery compartment and the old battery to see what you have. Brands like Zeee and Tenergy clearly state their connector, so you can match it before ordering.

Chemistry Determines The Charger

NiMH cells are common for RC and alarm systems and require a NiMH-specific charger. Lithium-ion packs, like the Panasonic camera cell, need a charger that matches their voltage—usually the one that came with your device. Using the wrong charger can damage the pack.

Capacity Is About Runtime

Higher milliamp-hours (mAh) means more runtime, but only if the physical size fits. A 5000mAh RC pack will outlast a 3600mAh pack, but it needs the same dimensions to drop into your car or truck.

In‑Depth Reviews

★ Best Overall

1. Panasonic DMW-BLC12 Lithium-Ion Battery for Panasonic Lumix®

Our pick — over 4.5★ from 850+ verified ratings; the strongest balance of quality and price.

Lithium-Ion1200mAh

This genuine Panasonic cell matches the factory part for reliable, all-day camera performance.

This is the exact battery you want inside a high-end camera body, because it is built by Panasonic for Panasonic gear like the DMC-GH2HK. At 1200mAh with a 7.2V rating, it delivers the trusted performance of a factory part, not a gamble on a cheaper alternative.

If you shoot with a Leica CL, buyers call this a bargain at half the price of other options, reporting “much more battery life than Kastar battery.” Its staying power means you can shoot a full day without swapping—one buyer notes it easily lasts that long.

Unlike aftermarket packs that can swell or leak, this one holds its shape and charges fast. It is the safest choice if you want to protect a premium camera body.

Owner consensus: The thing everyone raves about is battery life, and buyers consistently confirm the pack is authentic and identical to the original—right down to the 2.08-ounce weight that keeps the camera balanced.

Honest trade-off: The value-for-money verdict is split. Some see it as a steal for genuine OEM quality, while others find it pricey—so it suits buyers who value safety and longevity over the lowest price.

Reach for it if: you own a Panasonic Lumix or Leica CL and want factory-grade reliability with zero swelling worries.

Look elsewhere if: you are on a strict budget and willing to risk an aftermarket pack for your camera.

Best Value

2. Zeee 7.2V NiMH Battery 3600mAh RC Battery with Tamiya Connector

NiMH3600mAh

This affordable NiMH pack revives Tamiya-equipped RC cars with dependable 3600mAh power.

If you have an RC car, boat, or tank gathering dust, this Zeee pack is the cheapest way to get it running again. The 3600mAh capacity delivers real staying power—buyers report “plenty of power for 20-30 minutes of racing” in an RC boat.

It uses a standard Tamiya connector, so it drops into most hobby-grade vehicles from LOSI, HPI, and Kyosho without modification. The 12.96-ounce weight and 5.33 x 1.79 x 0.89-inch form factor fit standard battery trays.

What wins people over is the performance-to-price ratio. It brings an old snow blower back to life or upgrades an RC tank battery, and it arrives with a partial charge so you can test it immediately.

Why owners love it

  • Performance is the top praised aspect, with 28 owners noting it revives RC vehicles.
  • Quality scores high too—27 buyers call it well-built and long-lasting.

Things to watch

  • The capacity rating is mixed—some confirm the full 3600mAh, a few disagree.
  • You must use a NiMH-specific charger; charging at 0.5C (2A) made one pack hot.

The smart budget pick: best if you need a reliable NiMH cell for a Tamiya-equipped RC vehicle without spending premium money.

A fair warning: this is a high-current cell—never charge it unattended and stick to a NiMH charger.

Pro Fit

3. Tenergy 7.2V 2000mAh Replacement Battery for iRobot® Braava® 380 380t 390 390t & Mint®

NiMH2000mAh

This direct-fit NiMH cell restores full cleaning runtime to iRobot Braava and Mint mops.

When your Braava 380t starts dying mid-clean, this Tenergy pack is the direct replacement that fits straight into the compartment. It is rated for up to 500 charge cycles, which means it should last as long as the original battery did.

The 2000mAh capacity recharges fully in about 4 hours, so your mopper spends less time parked and more time cleaning. It measures just 1.2 x 2.1 x 1.7 inches, which is a 4.4x smaller footprint than the Zeee RC pack—tiny enough to slip into the robot’s sealed bay.

One Mint owner reported their unit lasted 15 months with regular biweekly use—solid return for the price. The functionality is what owners praise most, with 90 buyers confirming their 380t runs perfectly after installation.

Easy install: 20 buyers highlight how simple it is to fit—just a large screwdriver and a few minutes. The recurring honest note is that battery life is mixed, with some packs not holding a charge as long as others.

Who it serves: perfect for Braava 380, 380t, 390, 390t and Mint 5200 series owners who want a cheap, functional revival.

Best for: robot-mop owners who want a painless swap that restores a full hour of cleaning.

Think twice if: you expect multiple years of daily use—some buyers see a noticeable drop after a year.

Security Pro

4. HQRP 2600mAh Backup Battery for 2gig Go Control Panel

NiMH2600mAh

This 2600mAh NiMH backup clears the low-battery alarm in 2gig Go Control panels.

An alarm panel that beeps for a new battery is a constant annoyance. This HQRP pack replaces the internal cell in 2gig Go Control panels and wipes the failure message off the LCD screen—one owner cleared it in about 10 minutes with just a small Phillips screwdriver.

The 2600mAh NiMH cell is heavier than the camera packs at 7 ounces, but that weight is exactly what holds a snug fit inside the panel bay. Owners mention it fits perfectly and takes just two minutes to swap in for the old one.

Build quality wins people over—24 buyers call it high-quality, and the 1-year warranty adds confidence. It drops in as a direct replacement for BATT1, BATT1X, and BATT2X part numbers, so you do not need to rewire anything.

Easy DIY fix: 23 owners highlight the simple install, often cheaper than calling a security company. The honest trade-off is battery life—some panels demand a new cell within four months.

Replacement quality: 13 buyers confirm it is a perfect match for the original, clearing alarms and restoring the screen backlight.

Choose it if: you want a high-quality, easy-to-fit backup for a 2gig or Go Control security system.

Keep in mind: lifespan is variable—a few owners needed a fresh one within the year.

Alarm Value

5. ZZcell® Battery Replacement for 2Gig BATT1, BATT1X, BATT2X

NiMH2000mAh

This 2000mAh NiMH cell matches the original BATT1 part number for a silent GoControl panel.

This ZZcell pack is built to match the original 2gig BATT1 battery (and the 6MR2000AAY4Z part number) exactly, so it slides into GoControl panels with zero guesswork. At 2000mAh and 7.2V NiMH, it offers the same capacity as the factory cell.

Owners confirm it is a perfect fit in the GoControl 2 panel and that it solves the bad-battery beep immediately. The install is simple—one reviewer noted it matches the original battery and drops right in.

At just 4 ounces, it is the lightest alarm backup in this round-up, which makes handling the swap easy. Quality is the thing buyers praise most, with 10 owners calling it excellent and easy to fit.

Cost-saver: one owner highlighted it solved the panel issue at a price lower than the original replacement. The honest note is battery life—26 owners flag it as mixed, with longevity still unproven.

Solid accuracy: the part number and fit are exact, so this is a safe purchase if you just need a working spare.

Pick it for: a cheap, exact-fit backup that matches the original BATT1 part number for GoControl panels.

Expect: that long-term endurance is unverified—buyers admit they do not know how many months it will last.

High Capacity

6. MPF 3700mAh Battery for Honeywell Lynx 5100, 5200, 5210, Touch 7000

NiMH3700mAh

This 3700mAh NiMH pack provides the longest backup runtime for Honeywell Lynx panels.

This MPF pack brings 3700mAh of NiMH power to Honeywell Lynx 5100, 5200, 5210, and Lynx Touch 7000 systems—the highest capacity of any security battery here. That extra headroom means your panel keeps running longer when the wall power drops.

The 26.64Wh rating and 3-prong connector match the LCP500-4B part number exactly, and it includes a free installation tool in the box. One buyer who plugged it into an L7000 confirmed no low-battery error appeared, and the unit ran on battery alone for a while after unplugging from the wall.

Battery quality is what owners point to most, with 24 calling it a great replacement. It works especially well with ADT TSSC base units, according to the review pattern.

Installation ease: 10 buyers highlight the simple swap, and the included tool removes any need to buy extra hardware. The honest caveat is battery life—a few customers note needing a replacement after about a month.

Warranty backup: the 1-year replacement warranty gives you coverage that budget no-name packs rarely offer.

Ideal for: Honeywell Lynx owners who want the highest capacity and a free install tool in the box.

Note the risk: despite great quality, a minority of buyers saw the cell drain within a month.

Power Tool

7. Shentec 2 Pack 3000mAh 7.2V Battery Compatible with Dewalt DW9057

NiMH2 x 3000mAh

This two-pack of 3000mAh NiMH cells revives DeWalt 7.2V screwdrivers without memory effect.

If your old DeWalt 7.2V cordless screwdriver is collecting dust because the NiCd battery finally gave up, this two-pack of 3000mAh NiMH cells is the cure. It is rated at 21.6Wh and works with the original DeWalt charger that supports NiMH chemistry.

Reviewers point out these deliver more power than the originals and hold a charge between uses without the memory effect that plagued older NiCd packs. The 2-pack means you can keep one on the charger while the other is in the tool—no downtime mid-project.

The fit is the main praise point: 47 buyers confirm they fit perfectly in DeWalt power screwdrivers and charge properly on the OEM charger. Battery quality tops the list at 105 positive mentions.

The strong points

  • 105 owners rave about battery quality, and 98 confirm flawless functionality with DeWalt drivers.
  • No memory effect and low self-discharge means you can grab it after weeks and still have power.

The trade-off

  • Size is the recurring gripe—11 shoppers say these are slightly longer than the original DeWalt pack.
  • That extra length can stop your tool case from closing without a small modification.

Grab it if: you want to revive a DeWalt 7.2V driver and charge it on the original charger with zero memory-effect hassle.

Prepare for: a slightly longer pack that may require trimming your tool case to fit.

Long Runtime

8. melasta 7.2V 5000mAh NiMH RC Battery for Redcat Racing – Banana Plug

NiMH5000mAh

This 5000mAh NiMH pack delivers up to 45 minutes of runtime for Redcat RC trucks.

For Redcat Racing owners, this melasta pack is the runtime king. At 5000mAh, it is the highest-capacity cell on this list, and the 10C discharge rate pushes out 50 amps of max current for punchy acceleration off the line.

The real-world payoff is huge: buyers report the truck runs at full speed around 30 mph for 40-45 minutes without dying—long enough that “my kid gets tired of playing with it before the battery dies.” That runtime ends mid-session charging breaks for good.

It uses a Banana / HXT 4.0mm plug, so confirm your Redcat model uses that connector—it is compatible with the Everest Gen7 Pro, Sandstorm, Volcano EPX, and Thunder EPX drift.

What wins people over: battery quality (27 mentions) and the impressive battery life (20), with one drifter noting nearly 45 minutes on a charge. It is a great option if you do not want to switch to LiPo.

Charging discipline: the maker is strict—charge at 0.1C for 10 hours or 0.5C for 2 hours. Overcharging damages the pack, so follow the spec.

Reach for it if: you want maximum run time from a Redcat RC car without jumping to LiPo batteries.

Look elsewhere if: your ESC can handle LiPo—some buyers suggest it for even longer runs.

Complete Kit

9. Tenergy 2 Pack of 7.2V 3800mAh NiMH Flat Battery w/Charger

NiMH2 x 3800mAh

Two batteries and a smart charger in one box—the beginner’s whole setup solved.

This is the rare kit that removes the guesswork for RC beginners. You get two 3800mAh NiMH packs with standard Tamiya connectors plus a universal charger that handles any 6V, 7.2V, 8.4V, 9.6V, 10.8V, and 12V NiMH/NiCd pack.

Each 5.39 x 1.87 x 0.95-inch cell drops into Traxxas, LOSI, Team Associated, HPI, Kyosho, and Tamiya vehicles—including vintage buggies originally built for NiCad. Owners running a Tamiya Wild Willy Jeep with a brushless motor report 45-60 minutes of runtime per charge.

The charger lets you select 1 Amp for smaller packs or 2 Amps for anything over 2000mAh, and it includes a 12-month warranty. Battery life is what owners praise most, with 78 confirming the long run time.

Reliability: 76 buyers highlight dependable performance with zero issues over months of regular use. The charger gets credit for signaling when it is done and running cool without buzzing.

Honest notes: heat and durability are mixed—some packs run hot during hard use, and a few mention insulation breakage. Fit is also mixed, so measure your battery bay first.

Best for: beginners who want a complete, ready-to-run setup for hobby RC cars with a Tamiya connector.

Check first: your battery compartment size—fit is mixed across different chassis, so measure before you buy.

Understanding the Specs

Milliamp-Hours (mAh)

This number tells you how long the battery lasts between charges. A 5000mAh pack like the melasta runs a Redcat truck for 40-45 minutes, while a 1200mAh camera cell like the Panasonic holds enough for a full day of shooting. Higher mAh means more runtime, but only if the physical size still fits your device.

NiMH vs Lithium-Ion

NiMH (nickel-metal hydride) is the workhorse chemistry for RC cars, alarm panels, and power tools—it is cheap, rechargeable, and safe with a matching NiMH charger. Lithium-ion (Li-ion) packs are lighter and hold more energy per ounce, which is why Panasonic uses it for the 2.08-ounce camera cell. Your charger must match the chemistry.

FAQ

Can I use a 7.2V battery with a 7.4V charger?
No. A 7.4V charger pushes too much current into a 7.2V cell and can overheat or damage it. Always use a charger that matches the battery’s voltage and chemistry—NiMH cells need a NiMH-specific charger, never a LiPo one.
What is the difference between NiMH and NiCd batteries?
NiMH (nickel-metal hydride) holds more capacity than NiCd (nickel-cadmium) and does not suffer from the memory effect, so you can recharge it at any time without fully draining it first. The Zeee and Tenergy packs on this list are all NiMH, which is the modern standard for RC and alarm use.
Will a Tamiya connector battery fit my RC car?
Only if your car’s speed controller also uses a Tamiya connector. The Zeee 3600mAh and Tenergy 3800mAh packs both use standard Tamiya plugs. If your car uses a different plug like a Deans or banana connector, you will need an adapter or a different battery.
How long does a 7.2V battery last on a single charge?
It depends on the capacity and the device. The melasta 5000mAh runs a Redcat truck for 40-45 minutes at full speed, while the Tenergy 3800mAh two-pack provides 45-60 minutes in a Tamiya buggy with a brushless motor. Higher mAh always means longer runtime.
Can I charge a 7.2V NiMH battery with my DeWalt charger?
Only if the charger supports NiMH chemistry. The Shentec 3000mAh pack is designed to work with the original DeWalt charger that supports Ni-MH cells. A charger built only for NiCd will not properly handle a NiMH pack.
Why does my alarm panel keep beeping for a new battery?
The internal backup battery has lost capacity and can no longer hold a charge. Replacing it with a compatible pack like the HQRP 2600mAh for 2gig panels or the MPF 3700mAh for Honeywell Lynx clears the low-battery warning and restores the screen backlight.
Is a higher mAh battery always better?
Higher mAh means more run time, but the physical size must fit your device. The melasta 5000mAh is the biggest pack here, but it only fits RC cars that accept its dimensions and banana plug. Always check the battery compartment size before upgrading capacity.
How long will a replacement 7.2V battery last before it wears out?
Lifespan varies by chemistry and usage. The Tenergy 2000mAh for Braava robots is rated for up to 500 charge cycles, and one Mint owner reported 15 months of regular biweekly use. Alarm batteries like the HQRP tend to last a year or more, with some owners replacing annually.
What is the difference between the HQRP and ZZcell alarm batteries?
Both fit 2gig Go Control panels, but the HQRP is a 2600mAh cell with a 1-year warranty, while the ZZcell is a 2000mAh exact match for the original BATT1 part number. The HQRP offers higher capacity; the ZZcell is the lighter pack at 4 ounces.
Can I use these batteries in airsoft guns?
Yes, if the gun uses a standard Tamiya or mini Tamiya connector. The Tenergy 3800mAh kit includes adapters for standard Tamiya, mini Tamiya, and alligator clips, making it versatile for airsoft AEGs. Just confirm your gun’s connector and battery bay size first.

Final Thoughts: The Verdict

If you want one dependable pick, the 7.2 volt battery winner is the Panasonic DMW-BLC12 because genuine OEM construction and long-lasting performance matter most when protecting a camera body. If you are reviving an RC car on a budget, grab the Zeee 3600mAh. And for a dead robot mop, the Tenergy 2000mAh is the one to reach for. Match the connector, match the chemistry, and you will get years of reliable service from any of these picks.
