China NiMH D Size Rechargeable Battery 6V 9ah, Find details about China NiMH Rechargeable D Battery 9ah, NiMH-Hr20 from NiMH D Size Rechargeable Battery 6V 9ah
1. Adopt special sealing design and sealing technology, select high-energy battery special materials, and have superior leak-proof performance. The voltage is stable. Adequate capacitance, low temperature resistance and impact resistance. Shock storage period and long service life. The sightseeing is bright and tidy, small in size, light in weight, and does not corrode and rust.
2. Long life: Under normal use, the life is greater than 500 cycles.
3. Smooth discharge curve: When discharging with 0.1C to 100%, the voltage of each battery can still be maintained above 1.2 volts.
4. High adaptability: Any battery pack can be made according to user requirements to meet the requirements of users' products.
5. It is manufactured by advanced technology, with low internal resistance, fast charging and excellent abuse resistance;
6. Low self-discharge; high capacity and stable performance

A: Lower capacity rechargeable AA batteries of 1700 up to 2000mAh can be recharged up to 1000 times in overnight slow charge mode, while 2100 to 2400 mAh rechargeable batteries can be recharged up to 600 to 800 times in overnight slow charge mode.
The new higher capacity AA 2500 mAh rechargeable batteries have greater power capacity, but they can only be recharged approx 500 times in the overnight mode. Capacity improvement or quick charging will always decrease the number of cycles. Every cell available on the market above 2100 mAh will have below 1000 charge cycles.
A: NiMH batteries self discharge about 1% per day so if used in a low energy consummation or stand-by device, the battery will only last about 90 days before requiring recharge.
A: Any situation where the battery is not used within a 30 day period or low energy draw devices, for example smoke alarms, emergency flashlights, clocks, TV remotes, etc.
