NIMH 4/5A1800mAh 1.2V battery with UL IEC/EN61951 certification.

1. Specification of the battery pack:

Open circuit voltage:         ≥ 1.25VTypical weight: 5.7g approx

Internal iedance(RI) :   ≤55mΩ

Low terature discharge(0.2c 0℃) :   ≥54 min

2. Safety test

Over discharge: 0.1C charge for 48hrs No conspicuous deformation and/or leakage.

Charge reserve: Standard charge Storage: 28 days Standard discharge (0.2C) ≥180min

Humidity: Standard charged, stand for 10 days at 33±3℃ and 80±5% of relative humidity No leakage

External Short Circuit: After standard charge, short-circuit the cell at 20 ℃ ± 5 ℃ until the cell teerature returns to ambient teerature.(cross section of the wire or connector should bemore than 0.75mm2) No fire and no
explosion

Vibration Resistance: Charge of voltage should be under 0.08V/pack, change of iedance should be under20milli-ohm/cell.

Drop Test: △V<0.02V/cell △Ri<5%/cell Charge at 0.1C for 16hrs,and then leave for 24hrs,check battery before / after drop
