Battery Weight Compare: Lithium vs AGM

Same usable power, very different weight. Compare with your own numbers.

Usable capacity and weight both differ between lithium and AGM. This works out the battery size and weight for the usable energy you need. The weights are typical examples. Use the real figures for the batteries you are looking at. Everything is worked out in your browser. Nothing is saved or sent anywhere.

How it was worked out

    What this does and doesn't tell you

    • Check your vehicle's payload and the weight limits for where the battery is mounted.
    • Batteries must be properly secured. A loose battery is dangerous in a crash.
    • Work on 240V AC wiring, including inverter outputs and mains inlets, must be done by a licensed electrician. For high-current DC gear, follow the maker's installation manual and have an auto electrician check your work if you're unsure.
