Lead acid batteries usually come with no BMS/PBM which are more likely to be overcharged resulting in prolonged exposure to heat, which can damage the batteries or lead to a fire in extreme cases. The IN2902000 SLA 29V charger was tested to EN 60335 standard to be safe in any normal and abnormal conditions. It is engineered and manufactured in conformity with the CE/LVD standards: EN 60335-1, EN 60335-2-29, IEC 60335 2 29 and the Class 2 standard UL 1310. The 29V charger effectively charges batteries while protecting the batteries from over-charging.
