Understanding the Technology

The MXTS 40 uses multi-stage pulse charging combined with desulphation technology to safely restore and maintain lead-acid and AGM batteries degraded by heat cycling — a common issue across India's extreme climate zones. Its microprocessor-controlled algorithm continuously monitors voltage, temperature, and current, adjusting output in real time. This prevents overcharging, which is especially critical given India's frequent grid instability. The result is maximised battery lifespan and reduced replacement costs for professional operators.
