Development of lead/acid batteries for photovoltaic power systems

In order to increase charging efficiency and reduce maintenance such as topping up, lead/acid batteries should not be overcharged. However, when they are used for long periods without overcharging, stratification of the electrolyte can result because the electrolyte is not agitated by the gas evolved during overcharging, thus reducing battery life. In consequence, we have developed two types of lead/acid batteries: vented (Model SLB), and sealed (Model SRE), for photovoltaic power applications.
