Motorcycle battery maintenance/recharging 2021 Harley Davidson FB

Start, warm up, and drive your motorcycle regularly otherwise you'll need to keep it maintained and charged in-between usage. Battery Tender Junior 800 does the job and gives different charging options for different applications.
Other tips:
- Key fob battery might need replacing.
- Know your PIN, just in case, if applicable.
- Starter wires may be loose, unplug and plug back in, if applicable.
- Many bikes have a charging wire tucked away someplace!
