12V 100Ah LiFePO4 Battery Runtime Calculator

How Long Will a 12V 100Ah LiFePO4 Battery Run?

Use this planning tool to estimate runtime for the WinPower 12V 100Ah LiFePO4 Battery. It is a planning estimate, not a guaranteed duration.

Estimate your runtime

Start with your average load. This planning estimate is not a runtime guarantee.

Nominal: 1280 Wh · Adjusted: 1088 Wh · Estimated runtime: 10.88 hours at 100 W.

Wh = volts × Ah. Adjusted Wh = Wh × factor / 100. Runtime = adjusted Wh ÷ load watts. The 85% factor is illustrative, not a measured efficiency rating; account for losses and reserve once, not twice. Actual runtime varies with load, temperature, wiring, inverter efficiency and battery condition. This tool does not establish voltage, current or wiring compatibility.

How to Plan a Real Setup

  1. List the devices you expect to run and their wattage.
  2. Account for duty cycle, startup loads and inverter loss.
  3. Compare the estimate with your desired reserve and recharge window.
  4. Confirm voltage, charger and wiring requirements before installation.
