Prt Number: PMNN4407BR
Weight(g): 130g, Chemistry: LiIon
Usage: approx 11hrs DP2000 (Digital) 15hrs DP4000
Capacity (mAh): 1650mAh (Typical)
Intelligent: Yes, IP68
Memory Effect: None, Intrinsic Safety: 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.
