Service Life Expectancy |
The expected operating service life of the NP series is 3 to 5 years. This can be achieved under optimal operating conditions if a permanent battery temperature of 20°C is maintained. The battery with a float charge voltage of 2,275V/cell is charged and one of the local constant charging currents does not cross the effective ripple current value of 0,1CA. |
