HxWxD (mm):120.69 x 60.36 x 23.35
CP040 OpTime:19hrs, DP1400 OpTime: 23hrs Dig, 18hrs Ana
Capacity: 2900mAH (Typical) / 2800mAH (Min), Weight: 145g
Charge Cycles: 300, 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.
