A – The terminal voltage for all models is 2V.

B – Ah rating is measured @ 25°C with end voltage per cell (EVPC) = 1.80V. The actual battery performance may be ±5% of the figures shown above.

C – SCC means Short Circuit Current and its unit is Amperes.

D – IR means Internal Resistance and its unit is milli-ohms.

E – TT means Terminal Type.

F – Actual dimensions may vary by ±1%.

Charging Instructions

Constant voltage charging is recommended.

Charge to at least 2.3V but no more than 2.35V.

Constant under or over charging will damage the battery and shorten its life significantly.

Temperature compensation to be applied for temperatures ranging from 0°C to 40°C is as follows: subtract 3mV / °C / cell above 25°C (add 3mV / °C / cell below 25°C).
