Store description excerpt
Battery Calculator & Converter is a handy tool designed to simplify battery planning and comparison. Easily calculate battery runtime, capacity, and energy requirements across various chemistries and sizes. Convert between mAh, Wh, voltage, and other key metrics in seconds. Whether you're designing projects, troubleshooting devices, or exploring power options, this app provides accurate results and intuitive functionality—perfect for hobbyists, engineers, and anyone working with batteries. With our "Battery Calculator & Converter" app you can do the following: - Battery Runtime with Peukert: Estimate realistic battery runtime from bank capacity, load, efficiency, and Peukert exponent. - Cranking Amps vs Temperature: Estimate available cranking amps at current temperature and check starting margin against starter motor draw. - Alternator / Charger — Time to Full: Estimate time for alternator or charger to bring battery from current to target state-of-charge. - Inverter Runtime + Surge Check: Calculate runtime at continuous inverter load and verify surge demand versus battery bank and C-rate limits. - Battery SoC from OCV: Estimate battery state-of-charge from rested open-circuit voltage, considering chemistry and temperature where applicable. - Solar Recharge Time — Aux Battery: Predict hours or days needed for solar array to recharge auxiliary battery to target state-of-charge. - Ah ↔ Wh Converter: Convert between amp-hours and watt-hours using system voltage, with presets for common DC battery systems. - DC-DC Charger Sizing: Choose an appropriate DC-DC charger current based on alternator rating, vehicle base loads, and battery size. - Series–Parallel Bank Planner: Plan series-parallel battery configurations to reach desired system voltage and capacity with total Ah and Wh. - Voltage Drop & Wire Gauge (DC): Calculate DC voltage drop over cable length and recommend suitable wire gauge for allowed loss.
