AA and AAA NiMH Battery Models: The Complete Capacity List We Supply
When you need to source AA and AAA NiMH battery models for a product line, the first practical question is rarely about chemistry theory. It is usually: which specific models exist, what capacities are available, and how do I pick the right one for your device?
This article lists every AA and AAA NiMH battery model we supply — 20 models in total — followed by a practical capacity-selection guide. All of these cells share a 1.2V nominal platform and are available for wholesale, OEM, and ODM programs. For the deeper technical background on voltage behavior and procurement, see our companion guide: Reliable 1.2 Volt Rechargeable Battery: Specs, Applications & Bulk Sourcing Pitfalls.
What Are AA and AAA NiMH Battery Models?
AA and AAA NiMH battery models are cylindrical, rechargeable nickel-metal hydride cells rated at a 1.2V nominal voltage. They are designed as a reusable replacement for disposable 1.5V alkaline cells in a wide range of consumer and industrial devices. The two sizes differ only in physical dimensions — AA is larger and holds more capacity, AAA is smaller and lighter.
Unlike disposable cells that are thrown away after a single use, these models can be recharged hundreds of times. Their chemistry is well documented — you can review the fundamentals on Wikipedia’s Nickel-Metal Hydride Battery page or the technical deep-dives at Battery University.
AA vs AAA: Two Sizes in Our AA and AAA NiMH Battery Models Lineup
The size is dictated by your device’s battery compartment — the diameter and length must fit physically. In our lineup, the AA and AAA NiMH battery models below cover the full spectrum from compact to high-capacity.
| Size | Diameter | Length | Capacity Offered |
|---|---|---|---|
| AA (5号) | 14.0 mm | 50.5 mm | 100 – 2000 mAh |
| AAA (7号) | 10.5 mm | 44.5 mm | 100 – 800 mAh |

How to Choose the Right AA and AAA NiMH Battery Models for Your Device
The mAh number tells you how much energy the cell holds — the higher it is, the longer the device runs per charge. To match the right AA and AAA NiMH battery models to your product, follow this practical rule for the whole family:
- 100 – 600 mAh: fits low-power, always-on devices where per-charge run time is not the bottleneck — wireless mice, clocks, simple remotes. Keeping capacity low also keeps unit cost down.
- 600 – 1000 mAh: a good middle ground for mixed-use products such as toys, portable radios, and LED fixtures that need a balance of runtime and size.
- 1000 – 2000 mAh: reserve the top end for products that drain quickly and run frequently — cameras, flashlights, game controllers — where longer runtime between charges matters most.
A simple tip: look at how often you replace batteries in that device today. If it is weekly, choose a higher-capacity model from the AA and AAA NiMH battery models list above; if it is monthly or beyond, a lower capacity grade will serve well and save cost.
Why Buyers Standardize on AA and AAA NiMH Battery Models
Because every AA and AAA NiMH battery model in this lineup shares the same 1.2V nominal voltage and the same production quality standards, you can source multiple capacities from one supplier without worrying about inconsistent behavior across your product range. That simplifies inventory, reduces qualification effort, and keeps your supply chain predictable. When shipping these cells internationally, qualified suppliers provide the required UN38.3 transport documentation and can reference the IEC 62133 safety standard for industrial-grade projects.
Frequently Asked Questions About AA and AAA NiMH Battery Models
What does the mAh number mean?
It is the nominal capacity — how much electrical charge the battery stores. Higher mAh means longer run time per charge.
Are all the models in this list 1.2V?
Yes. Every AA and AAA model listed here operates at a 1.2V nominal voltage.
How do I know whether to order AA or AAA?
Open the device’s battery compartment. The required size is fixed by the compartment’s diameter and length; then choose the capacity according to your power-draw needs.
Do you offer custom capacity or OEM packaging?
Yes. Beyond the standard models above, we support OEM/ODM customization. Contact us with your target capacity and packaging requirements.
