Tech Note - Cold Weather and Genset Batteries
Battery blanket heaters are frequently used during winter in cold climates to keep starting batteries from freezing and improve cranking performance. In cold temperatures chargers with local temperature compensation increase output voltage because their onboard temperature sensor is cold. This causes the warm battery to be overcharged, causing more rapid water loss (“boiling”) and shortened battery life. Download the technical advisory to learn how to avoid this problem.
