If lead-acid batteries are over discharged or left standing in the discharged state for prolonged periods hardened lead sulphate coats the electrodes and will not be removed during recharging. Such build-ups reduce the efficiency and life of batteries. Over charging can cause electrolyte to escape as gases. Types of Lead-Acid Battery
A SLA (Sealed Lead Acid) battery can generally sit on a shelf at room temperature with no charging for up to a year when at full capacity, but is not recommended. Sealed Lead Acid batteries should be charged at least every 6 – 9 months. A sealed lead acid battery generally discharges 3% every month. Sulfation of SLA Batteries
Lead Acid Battery Cycle Charging. Cyclic (or cycling) applications generally require recharging be done in a relatively short time. The initial charge current, however, must not exceed 0.30 x C amps. Just as …
Continuous charging can: cause corrosion of the positive battery plates; cause increased water consumption; even allow for excessive temperatures causing damage inside the battery. This continuous heating from overcharging can destroy a battery in just a few short hours. Pro tip: a good rule of thumb to help avoid the trap of overcharging is to make sure you charge your …
