Is it bad to keep lead acid batteries near fully charged?

The lead acid chemistry likes to be close as possible to 100 percent charge. A car battery will get f''ed up if you discharge it below 50% a few times whereas a deep cycle lead acid battery will handle below 50% for hundreds of cycles. But keeping a deep cycles above 50% at all times is crucial to keeping its lifespan up.

Charging lead acid batteries in series

This is a problem when series-charging lead-acid batteries and it is generally not recommended. The battery''s condition is dependant on the specific gravity of the sulphuric acid electrolyte. Of course the 6 individual 2V cells in each battery share the same electrolyte which is why they can be charged in series but separate batteries can''t.
