Overview
An 800mA output and a switch between lead-acid and lithium modes define the Battery Tender Junior, a 12V charger and maintainer built for motorcycles, ATVs, UTVs, personal watercraft and scooters rather than full-size car batteries.
At 800mA this is a maintainer for small powersports batteries, not a fast charger, and its job is to sit connected long-term without overcharging rather than bring a dead battery back quickly. Long-time users describe running these for years across multiple vehicles, fitting a charger meant to be left on a battery through an off-season rather than used for a quick top-up.
- 800mA, switchable lead-acid or lithium (LiFePO4)
- Spark-proof connection with reverse-polarity detection
- Built for motorcycle, ATV, UTV, personal watercraft and scooter batteries
- 5-year warranty, ETL/FCC/ICES certified
Who it's for
Suits owners of motorcycles, ATVs, watercraft or scooters who store a vehicle for months at a time and want the battery ready when it comes back out. Not the choice for anyone needing a fast charge or a charger sized for a full-size car battery.
What buyers say
From Amazon customer reviews.
Reviewers with over 20 years of Battery Tender use say the brand has never let them down, and multiple owners keep one dedicated to each motorcycle, mower or car for that reason. One buyer compared it favorably to a NOCO Genius 1 that gave inconsistent indicator lights and needed two warranty replacements; another noted this charger has few status lights but still kept a battery charged through an unheated shed in near-zero weather.
Strengths and trade-offs
Drawn from this product's published specifications.
- 800mA output is slow, not meant for fast charging
- Minimal status lights compared to chargers with a full display
Performance notes
The switchable mode lets the same unit maintain lead-acid or lithium batteries correctly rather than applying one charge profile to both, and the microcontroller updates the charge sequence continuously so a battery left connected does not overcharge. Reviewers who have used these for years, including through an unheated shed in single-digit temperatures, say the battery stays ready without needing to check on it.
