Equalization charges should be performed as suggested by the battery manufacturer, but many companies equalize their batteries over the weekend due to the long charging cycle. A full charge cycle is around eight hours for a standard lead-acid battery and the equalization charge can be around an additional three hours.
How long does battery equalization take?
Equalizing is a high voltage charge that will convert lead sulfate back into active material. This has to be done within a reasonable amount of time for it to work. As stated earlier, the longer it goes on the harder it becomes to remove. Our batteries should be equalized at 15.5-16.3 volts for 6-8 hours.
Some manufacturers recommend monthly equalizations for 2–16 hours. Most VRLAs vent at 34kPa (5psi), and repeated venting leads to the depletion of the electrolyte, which can lead to a dry-out condition. Not all chargers feature equalizing charge.
