Customer reversed the polarity of battery, how do I fix it?

A customer has a truck fleet and somehow he reversed the polarity of the battery. I completely discharged the battery and tried a charger on it but it still sparks hard when I try to put the leads on correctly. It''s a 12v lead …

Customer reversed the polarity of battery, how do I fix it?

Originally lead acid batteries had no difference between the positive and negative plates and the polarity was determined entirely by the initial charge. Modern batteries use different paste materials or even completely different construction for the two plates and the reverse polarity capacity would be much reduced.

Blog about Marine Solar Panels, Solar Systems, LiFePo4 Batteries

We are often asked if there is a way to keep a lead acid start battery and install LiFePO4 batteries for the house and charge them from the same alternator. The answer is generally yes. Lead acid or AGM batteries should never be combined with LiFePO4 batteries.

The Uncensored Guide To Charging A Deep Cycle Battery

While this is not required for sealed deep cycle batteries, flooded lead acid batteries should be equalized occasionally to make sure each cell is equally charged. You can do this by applying a controlled overcharge once every 30-90 days, or whenever individual batteries are imbalanced, that is they are reading a different voltage.

What is a Lead-Acid Battery? Construction, Operation, and …

Lead-acid batteries should never be allowed to remain for a long period in a discharged state because lead sulfate could harden and permanently clog the pores of the electrodes. Before storing it for a long time the battery should be completely charged, then the electrolyte should be drained so that the battery is stored dry.
