BU-403: Charging Lead Acid
Figure 4: Charge efficiency of the lead acid battery [2] At the right temperature and with sufficient charge current, lead acid provides high charge efficiency. Source: Power-Sonic Argument about Fast-charging. Manufacturers recommend a charge C-rate of 0.3C, but lead acid can be charged at a higher rate up to 80% state-of-charge (SoC) without creating oxygen and …
