“PWM” – Pulse Width Modulation is the most effective means to achieve constant voltage battery charging. PWM regulation tapers the voltage according to the battery’s condition and recharging needs. PWM has recently surfaced as the first significant advance in battery charging.

• Ability to recover lost battery capacity.
• Dramatically increase the charge acceptance of the battery.
• Maintain high average battery capacities (90% to 95%) compared to on-off regulated state-of-charge levels that are typically 55% to 60%.
• Reduce battery heating.
• Automatically adjust for battery aging.
• Self-regulate for voltage drops and temperature effects in charging systems.
