Lithium Polymer replacement battery for newer generation AltimeterOne, AltimeterTwo, AltimeterThree, and Chute Release. Please make sure your altimeter looks like the one in the Visual Repair Guide.

All rechargeable batteries wear out. Once your battery life drops below a full day’s usage, we recommend you purchase a replacement, which snaps in. Jolly Logic altimeters use custom batteries with special connectors designed to fit your product—do not attempt to replace with another type.

Check out our Visual Repair Guide to see how to replace your worn out battery.

Never allow your rechargeable devices to run completely dead. Recharge at least every 4 months, or your battery will be ruined.
