A low-current charger and maintainer for powersports batteries, with a switch for lead acid or lithium. The output is small, so it maintains and slowly tops up rather than rescuing a large car battery.

Overview
Battery Tender makes this Junior model as a switchable charger and maintainer for powersports batteries. A switch sets it for lead acid or lithium, and the charger can stay connected to hold the battery between rides.
Two battery chemistries and two connection options make it flexible for a garage with mixed batteries. The limitation is the small output, which is built for maintenance and powersports sizes.
Who it's for
Owners with a lead acid or lithium battery who store the vehicle for weeks can leave it connected as a maintainer. Drivers wanting a quick boost for a dead car battery should use a higher-output charger.
Pros and cons
- Switch for lead acid or lithium
- Clips and ring terminals both listed
- Extended warranty term
- Safety listings include UL and CSA
- Low current suits small batteries only
- One port, one battery at a time
- Charge indicators not listed
Performance notes
A charger of this size delivers current slowly, so a depleted battery needs a long time to recover and a large battery may not recover at all. Once full, maintainer mode tapers to a trickle that offsets self-discharge. The switch matters because lead acid and lithium cells need different charge profiles.
