## Description

Battery Tender Junior 12V Battery Charger is much more than a trickle charger. It has a brain, is lightweight, compact, fully automatic and very easy to use especially in small spaces. This battery charger will keep the battery fully charged so that it is ready to go always. It has a microprocessor controlled fully automatic charger and maintainer and is designed to extend the life of any lead acid battery commonly used in automobiles, motorcycles, ATVs, personal watercraft, RVs, boats, airplanes, golf carts, back-up generator systems, etc. Any vehicle or battery-operated piece of equipment not used on a daily or regular basis is a candidate for a Battery Tender charger. The advanced technology will bring the battery back to a full charge without overcharging and then float or maintain the battery for an indefinite period of time. The Battery Tender Junior comes equipped with alligator clips and ring terminals for easy hook up. An optional 25 feet extension cord (part number 081-0148-25) is sold separately.

## Features

- Stay Charged: Battery Tender battery chargers and maintainers provide a full charge to your powersport vehicle’s battery before switching to float mode to maintain proper voltage levels for safe, long-term storage
- Extend Battery Life: Compatible with all 12V lead-acid, flooded, AGM, and gel cell batteries. Complete 4-step charging program (Initialization, Bulk Charge, Absorption Mode, Float Mode) allows for optimization of battery power, without overcharging or battery damage. Smarter than a trickle charger.
- Includes: 12V, 750mA battery charger, ring terminal and alligator clip combo cable, 5-year warranty, and lifetime customer support
- Simple & Safe: Low maintenance, easy-to-use, universal battery charger is just 4.4” x 2.15” x 2.9”, 0.65lbs (charger only). Spark-proof circuitry ensures no-spark connections, and automatic reversed hook-up detection verifies correct connection
- Monitor Power Levels: Two-color charge status LED light indicates the state of the charge and if the battery voltage drops too far under load, adaptive charging will resume full charger output power. Automatic charge cycle functionality switches to float mode after fully charging the battery. It is ETL US/CSA, FCC, ICES, BC, certified.

## Questions & Answers

**Q: Does this also come with uk connectors and work on 230v? it looks like american 110v connectors in the picture.**
A: Do not try to power the Battery Tender Junior with our British 240V supply as I did !   You will likely render it inoperable.  What you will need is a suitable 240V to 110V Step Down Converter.  Amazon, for instance, sell such a model.

**Q: Does this basket have holes for ventilation so that sweaty clothes can breathe?**
A: our laundry basket is breathable and should be able to handle sweaty clothes.

**Q: can i leave this permanently connected to an automatic start stop generater**
A: Yes these are fine to leave connected permanently
