High current cell with a current capacity of up to 60A!
Internal resistance: 12 mOhm only (1 kHz AC)!
Capacity after 500 cycles, with 4A charging, discharging at 10A: still about 86%!
Warranty is DOA only. Domestic customers have 7 days from delivery date to report a DOA battery. International customers have 30 days to report DOA due to extended delivery times for international orders.
WARNING: These IMR cells have much lower internal resistance than regular LiIon 3.7V cells and they may end up with a higher ending voltage when charged in certain chargers ( especially an older version WF-139 charger ). Please check the voltage of them right out of the charger to see if they are above 4.20V when fully charged with your charger. Overcharging above 4.25V may shorten life/cycles. Above 4.50V may even pop them or make them leak. DO NOT use the charger if it seems to overcharge IMR cells.
- Do not over-discharge/overcharge
- Recharge empty batteries ( resting voltage ~3.6V ) as soon as possible. Leaving LiIon batteries in discharged state will incur irreversible damage ( capacity / cycle loss )
- Do not short circuit ( will release tremendous current )
- Do not dispose of in fire.
* General Information *
mAh = Miliamp Hours: This generally refers to the amount of energy a fully charged battery can store. A higher mAh rating does not generally offer any short term improvements, although a higher mAh rating does indicate that a fully charged battery will preform over a longer period of time. For example, a 1100 mAh battery will operate a device drawing 100 milliamps for 11 hours and a device drawing 1100 milliamps for 1 hour. The amount of milliamps that your mod will draw depends on the voltage of the battery (and/or any switch contained in the mod) and resistance (ohm). If you are in-doubt, contact the mod manufacturer or have your mod tested at a local electronics shop
