It supports AGM, GEL, SLA, flooded and deep-cycle batteries (4–100Ah), includes temperature-compensated charging and a clear color LCD to show voltage, current and temperature. It is not compatible with lithium-ion or higher-voltage battery systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly will this charger restore a drained 12V battery?\u003c\/h3\u003e\n\n\u003cp\u003eThe charger provides a fast constant-current phase up to 6A, which charges batteries faster than typical 1–1.5A trickle chargers, then tapers through multi-stage charging to protect the battery. Recovery speed depends on battery capacity and state of discharge, but the higher 6A peak shortens refill time for small-to-medium lead-acid batteries.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e6A peak current for faster initial charging\u003c\/li\u003e\n  \u003cli\u003eSmart multi-stage algorithm prevents overcharging\u003c\/li\u003e\n  \u003cli\u003eAutomatic switch to float mode for long-term maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan it revive an old or sulfated battery?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the unit includes pulse desulfation technology that uses dual-frequency pulses to reduce sulfate buildup and address acid stratification. This function can help bring under-voltage or long-dormant lead-acid batteries back to workable condition, though severely damaged batteries may remain unrecoverable.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eDual-frequency pulse desulfator targets sulfate crystals\u003c\/li\u003e\n  \u003cli\u003eWorks on batteries left unused or stored for long periods\u003c\/li\u003e\n  \u003cli\u003eImproves chances of restoring serviceable batteries\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat safety features and protections are included?\u003c\/h3\u003e\n\n\u003cp\u003eMultiple safeguards are integrated to protect both battery and charger, including overcharge, overcurrent, overvoltage, reverse polarity, short-circuit and thermal protection.
