StarkPower Deep Cycle 12V9-EP

World Class Safety Features

World Class Safety FeaturesStarkPower Deep Cycle 12V9-EP has 12 volts and a 9Ah capacity and is perfect for powering your deep cycle systems. StarkPower Deep Cycle has an internal microprocessor controlled battery management system (BMS) that monitors the key operational parameters during charging and discharging, such as voltages, currents and internal temperatures.

Built for Long Lasting Reliable Power

Built for Long Lasting Reliable PowerThe StarkPower Deep Cycle Battery has a cycle life of 3,000 cycles or about 10 calendar years. Our lithium-ion batteries have a usable capacity of 99% compared to 50-60% for traditional lead-acid batteries]. StarkPower Deep Cycle batteries function in the widest range of temperatures with a discharge temperature range (Functional) of –20°C to 60°C (–4°F to 140°F) and a charge temperature range of 0°C to 45°C (32°F to 113°F).

The StarkPower Deep Cycle line has the best weight to power ratio on the market

The StarkPower Deep Cycle line has the best weight to power ratio on the marketAt 2.55” (L) x 5.91” (W) x 3.99” (H) and weighing only 2.8 lbs., the StarkPower Deep Cycle 12V9-EP has the best size to power ratio of any deep cycle battery on the market. Connectors: F2, 0.25”, 6.4 mm Spade Terminals allow the battery to be installed in any direction unlike lead-acid batteries which are fixed. StarkPower Deep Cycle Batteries self-discharge rate per month is between 1-3% compared to lead-acid batteries which are about 30%. Max charge voltage is 14.6V and the discharge cut-off voltage is 10.5. Max charge current is 9A and max discharge current is 9A / 35A(3s). Can be charged with solar chargers. Can be charged with most traditional lead-acid chargers that do not have “Desulfate” mode, provided the current levels do not exceed lithium battery charge specification. Using a traditional lead-acid charger that reaches 14.4-14.6 volts will allow the battery to be fully charged. Chargers that do not exceed 13.6 volts will only charge the battery to 50% capacity or less.
