Description
Part Number: PMNN4491B
Weight: 130g, Capacity: 2100mAh
Chemistry: Li-Ion, Intelligent: Yes
OpTime (Hrs): 28/21.5 (D/A DP4000e), 18.5/14 hours (D/A DP2000e)
Intrinsic Safety: No
Memory Effect: No
Reliable: These have a significantly lower self-discharge rate than NiMH batteries.
Small: They are smaller and lighter compared to NiMH batteries.
Higher Voltage Output: A single cell can deliver 3.7v while even two NiMH cells can only give 2.4v.
Faster Recharge: Li-ions can be charged in about 1-3 hours, depending on capacity. This is much faster than the 10-12 hours needed for NiMH batteries.
Temperature Tolerance: These can better stand the low temperature and warmer environments compared to NiMH cells.
Higher Energy Density: This means that the battery carries more charge per gram than a NiMH battery.
