3.6V AA 800mAh Nimh Battery Pack

Looking for cost-effective Ni-MH battery packs? Choose the 3.6V AA 800mAh Nimh Battery Pack manufactured by Vcell Power from China. This pack consists of three high-consistency AA Ni-MH cells connected in series and adopts rigorous assembly technology with a compact size. The stable 3.6V output voltage effectively prevents device restarts and malfunctions caused by voltage fluctuation. With more than 500 recharge cycles, it is economical and eco-friendly. Its wide discharge temperature range from -20℃ to 75℃ fully meets the operating demands of devices working in high-temperature environments. Founded in 2001, Vcell Power runs an automated and intelligent production base for Ni-MH batteries with a complete set of product certifications.

Core Advantages

The product integrates outstanding stability, durability and environmental adaptability. The detailed advantages are listed as below:

1. Stable Voltage Output

This battery pack delivers a nominal voltage of 3.6V by connecting three 1.2V Ni-MH cells in series. Compared with disposable 3.6V lithium battery packs, its voltage drops much more gently during the whole discharge cycle, effectively avoiding device instability and unexpected restarts caused by voltage fluctuation. This feature is particularly critical for smart door locks, emergency lights and other equipment requiring continuous and reliable power supply.

2. Over 500 Charge Cycles

At 80% depth of discharge, the 3.6V AA 800mAh Nimh Battery Pack supports more than 500 charge and discharge cycles. Estimated based on typical application scenarios:

Smart Door Locks: 10-20 unlock operations per day, recharging every 6-12 months, usable for 5-10 years

Emergency Lights: Monthly function test and emergency use during power cuts, service life over 10 years

Model Remote Controllers: 2-3 hours of use per week, recharging every 3-6 months

Compared with disposable batteries that need frequent replacement, rechargeable Ni-MH batteries can cut the total lifecycle cost by more than 80%.

3. Wide Operating Temperature Range (-20℃ to 75℃)

Excellent high-temperature resistance is a key technical highlight of Ni-MH batteries. This pack supports discharge up to 75℃, higher than the 60℃ upper limit of ordinary lithium-ion batteries. It is perfectly suitable for:

Outdoor Emergency Lights: Internal temperature can exceed 60℃ under direct sunlight in summer

Equipment Cabinets: Communication devices and industrial control cabinets with high internal temperature

Car Interiors: The temperature inside a closed car can rise above 70℃ in hot summer

Medical Equipment: Devices exposed to high temperature during disinfection and transportation

In addition, the -20℃ low-temperature discharge capability meets the use demands of outdoor devices in cold winter.

4. Built-in Safety Valves

Each AA cell is fitted with a built-in mechanical one-time pressure relief safety valve. When internal pressure rises sharply due to abnormal conditions like overcharge, short circuit or reverse connection, the valve will open automatically to release pressure and prevent battery shell rupture and electrolyte leakage. This design makes Ni-MH batteries safer than ordinary disposable batteries without safety valves.

5. Economy & Environmental Protection

Ni-MH batteries contain no toxic heavy metals such as cadmium and mercury, bringing minimal impact on the environment after disposal. With over 500 reusable cycles, one single battery pack can replace more than 500 disposable batteries during its service life, greatly reducing solid waste.

Usage & Storage Guidelines

Follow the instructions below to extend the service life and ensure safe use of the 3.6V AA 800mAh Nimh Battery Pack:

Storage Requirements

Temperature: 10℃ ~ 25℃ is recommended. High temperature will accelerate self-discharge and capacity attenuation.

Humidity: Relative humidity ≤65%. Avoid moisture which may cause terminal oxidation.

Keep away from direct sunlight and heat sources.

Operation Notes

Use dedicated Ni-MH battery chargers only. Do not apply chargers for lithium-ion batteries or lead-acid batteries.

Fully charge new batteries before first use.

Stop use immediately if the battery is deformed, leaking or overheating abnormally.

Prohibited Operations

Do not short-circuit the positive and negative terminals with metal objects.

Do not throw into fire or expose to high heat.

Do not disassemble or modify the battery pack arbitrarily.

Do not reverse charge the battery.

Long-term Storage Tips

If stored for more than 6 months, charge the battery to around 50% state of charge.

Top up the power every 6 months to prevent capacity loss caused by excessive self-discharge.

Perform 1 to 2 complete charge-discharge cycles to activate the battery before reuse after long-term storage.

Waste Battery Disposal

Do not discard waste batteries into domestic garbage.

Deliver waste batteries to designated battery recycling points in accordance with local regulations.

FAQ

Q: Can this battery pack replace disposable 3.6V lithium batteries?

A: Yes. The 3.6V AA 800mAh Nimh Battery Pack has the same nominal voltage of 3.6V and can directly replace disposable 3.6V lithium battery packs for compatible devices. Please note to use a dedicated Ni-MH battery charger.

Q: Under what test conditions are the 500 charge cycles achieved?

A: The cycle life of over 500 times is tested at 80% depth of discharge under standard charge and discharge conditions. The actual cycle life will be affected by operating temperature, charge-discharge rate, depth of discharge and other factors.

Q: What is the function of the built-in safety valve?

A: When the internal pressure rises due to abnormal conditions such as overcharge and short circuit, the safety valve will open to release pressure and reduce the risk of battery bulging or rupture.

Q: Does it support fast charging?

A: Yes. The maximum fast charging current is 0.5C (400mA), which can fully charge the battery in about 2 to 3 hours. A smart charger is recommended to avoid overcharging.

Q: Can you customize battery packs with different sizes or capacities?

A: Yes. Vcell Power supports OEM and ODM customization for Ni-MH battery packs, including different series/parallel combinations, capacities, dimensions and connector types.
