Description
The Yuasa NP2.8-12 is an industrial Valve-Regulated Lead-Acid (VRLA) battery rated 12 V and 2.8 Ah at the 20-hour rate (2.5 Ah at the 10-hour rate). It has an internal impedance of 60 mΩ at 1 kHz and supports a maximum discharge current of 84 A for 1 second and 28 A for 1 minute. It floats at 13.65 V (2.275 V/cell) and accepts a cyclic boost charge of 14.5 V (2.42 V/cell) at 20C.

The Yuasa NP2.8-12 is an industrial Valve-Regulated Lead-Acid (VRLA) battery rated 12 V and 2.8 Ah at the 20-hour rate (2.5 Ah at the 10-hour rate). It has an internal impedance of 60 mΩ at 1 kHz and supports a maximum discharge current of 84 A for 1 second and 28 A for 1 minute. It floats at 13.65 V (2.275 V/cell) and accepts a cyclic boost charge of 14.5 V (2.42 V/cell) at 20°C.
The battery’s float charge voltage at 20°C is specified as 13.65 V (±1%) for the block and 2.275 V (±1%) per cell. Cyclic or boost charge voltage is 14.5 V (±3%) at block level and 2.42 V (±3%) per cell. Float charge current has no stated limit, while cyclic charge current is limited to 0.7 A. Storage capacity loss is approximately 3% per month at 20°C, and the nominal length is 134 mm (±1 mm).
