FirstPower Power battery Black sku-10855452347 Charger

FirstPower Power battery is a Black, waterproof 2-bank marine charger rated at 10A, or 5A per bank, for 24/7 charging. This Power Sources product also works as a battery maintainer, desulfator and vehicle charger. It supports 12V lead-acid and lithium-ion batteries, including marine, boat, starter and deep-cycle batteries.

Its three modes cover SLA/AGM, lithium and calcium batteries; the product description says it can charge up to three batteries simultaneously, with a mode selected independently for each. For a battery below 1V, hold the MODE button for 5 seconds to activate Force Mode; a blinking red power indicator shows it is active. The charger enters Repair Mode when needed, indicated by the 12V Repair light.

Diagnostics check for overvoltage, bad batteries, excess temperature and reverse connection. A thermal sensor adjusts charging to ambient temperature to prevent overcharging in heat and undercharging in cold conditions. SKU sku-10855452347; UPC 774049471564.
