Summary of NiMH Battery Models, Capacities And Applications

Summary of NiMH battery models, capacities and applications

NiMH batteries are a common rechargeable battery widely used in consumer electronics, power tools, hybrid vehicles and other fields. The following are the main models, capacities and typical applications of NiMH batteries:

I. Common models (classified by appearance)

Cylindrical batteries

AA (No. 5 battery)

Capacity: 600~2400mAh

Applications: digital cameras, remote controls, toys, etc.

AAA (No. 7 battery)

Capacity: 300~1200mAh

Applications: mouse, keyboard, small electronic devices.

C-type (No. 2 battery)

Capacity: 3000~6000mAh

Applications: high current equipment (such as flashlights, speakers).

D-type (No. 1 battery)

Capacity: 5000~12000mAh

Applications: industrial equipment, emergency power supply.

Sub-C (industrial model)

Capacity: 1200~4300mAh

Applications: power tools, drone battery packs.

Square battery (industrial use)

Capacity: 1Ah~100Ah+

Application: energy storage system, electric vehicle, backup power supply.

Button battery (button type)

Capacity: 20~200mAh

Application: watches, small electronic devices.

2. Special models and high-capacity batteries

Low self-discharge type (LSD Ni-MH)

Model: AA/AAA mainly

Capacity: 800~2500mAh (AA)

Features: Retain power after long-term storage.

High temperature/low temperature type

Operating temperature range: -40℃~70℃

Application: extreme environment equipment (such as military supplies, outdoor equipment).

Power type (high rate discharge)

Model: Sub-C, square

Capacity: 2000~5000mAh

Features: Support 10C~30C discharge (for power tools, RC models).

3. Summary of capacity range

Model Typical capacity range Applicable scenarios

AA (size 5) 600~2800mAh Home electronic products

AAA (size 7) 300~1200mAh Small portable devices

C type 3000~6000mAh High-power equipment

D type 5000~12000mAh Industrial/long-term power supply

Sub-C 1200~4300mAh Power tools/battery packs

Square batteries 1Ah~100Ah+ Electric vehicles/energy storage systems

4. Precautions

Capacity and voltage: The nominal voltage of nickel-metal hydride batteries is 1.2V (about 1.4V when fully charged), which is lower than alkaline batteries (1.5V), but the discharge is more stable.

Selection suggestions:

For home use, low self-discharge types (such as Eneloop) are preferred.

For high-power consumption devices (such as flashlights), high-capacity types (≥2500mAh) are selected.

Power tools need to be powered (supporting high current discharge).
