This blog covers lead acid battery charging at low temperatures. A later blog will deal with lithium batteries. Charging lead acid batteries in cold (and indeed hot) weather needs special consideration, primarily due to the fact a higher charge voltage is required at low temperatures and a lower voltage at high temperatures. Charging …
All lead-acid batteries discharge when in storage, so the right environment and active maintenance are essential. Sealed lead-acid batteries can be stored for up to 2 years, but it''s important to check the voltage and/or specific gravity and apply a charge when the battery falls to 70% state-of-charge.
