Learn MoreLead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems) With the CCCV method, lead acid batteries are charged in three stages, which are constant-current charge, topping charge and float charge.
Lead-acid batteries must be charged carefully. The chemical reaction involving the transfer of sulphate ions from the lead plates to the electrolyte can only go so fast. If too much current is supplied toward the end of the charging process, or if the battery is allowed to overcharge, gas can accumulate, leading to the loss of electrolyte.
Sealed lead-acid batteries, such as gel and AGM types, include a valve which allows excess gas to be released, but the electrolyte in those batteries cannot be topped up, meaning that they lose capacity if not charged correctly.
If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly discharged to below 50%. In flooded lead acid batteries this can cause plates to touch each other and lead to an electrical short.
The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 8–10 hours; however, without full topping charge. Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems)
In both flooded lead acid and absorbent glass mat batteries the buckling can cause the active paste that is applied to the plates to shed off, reducing the ability of the plates to discharge and recharge. Acid stratification occurs in flooded lead acid batteries which are never fully recharged.
