Lead-acid batteries are also 100% recyclable, with more than 98% of lead-acid batteries recycled, compared to the 97% of Li-Ion batteries NOT recycled.
All lead-acid batteries consist of flat lead plates immersed in a pool of electrolyte. We need to top up the battery regularly as some of this water is lost during the recharge cycle. Keeping the battery topped up will ensure that the plates are not irreparably damaged in the water level dips below the top of the plate. The second step and most important part of this maintenance process is using the correct water.
