White Paper | The Proper Charging of Stationary Lead-Acid Batteries


All too often, stationary batteries are not correctly or adequately charged. This leads to a shortened battery life and may also cause a premature and sometimes catastrophic battery failure. It is the author’s experience that almost 50 percent of all stationary batteries are not being properly charged. This observation is based upon hundreds of site visits, multiple battery system tests, and the examination of numerous maintenance records and warranty claims.

This paper intends to educate battery users on battery charging and detail the proper methods of float (maintenance) charging, recharging, equalize (boost) charging, adjusting the charge for temperature and limiting the charge current when necessary.
