Battery Tender Junior 12V, 750mA Charger and Maintainer: Automatic 12V Powersports for Motorcycle, ATVs, and More - Smarter Than a Trickle Charger - 021-0123

I have had this tender for over 2 years now and of course it works great. The brand is great, it keeps my motorcycle battery alive during the cold season. Easy to use and great value.

Must have item! This has kept our 12v car battery fully charged and functioning like a champ even in single digit freezing weather. Had to buy one because without it the battery kept dying even after replacing with a new one. No more dead battery issues after several weeks and so relieved that this was all we needed to resolve the issue. Love this charger!!

A great way to make mower and Ranger batteries last for years. Mower would only last a year before I started using these. It’s lasted almost 3 years now and still works great. Keep batteries water topped off and charged with these trickle chargers. I’ve never had one to fail. A real money saver.

top quality and works great .. they large clamps and long cord a big plus ..has a replaceable 7.5 fuse build in ..very safe to keep plugged in too..

These are the best! I have four of them on my, Polaris Ranger, Polaris Sportsman, John Deer Gator and John Deer mower. They work flawlessly! I never worry about them when they're hooked up. I use them all year round without incident. They are small lightweight and super reliable. They are either charging or maintaining the batteries all the time. The are especially useful in the winter. The cold drains a battery and this little guy keeps them charged. The new version comes with alligator clamps (I don't like) and they say you can use the loop holes on the clamp to connect to the battery terminal. Unfortunately those loop holes are too small to go onto a battery terminal. However you can buy Battery Tender "the quick connect ring terminals" with larger loop holes to attach to your battery terminals. I gave it 4 stars due to the newer product not having large loop holes.

An absolute necessity for motorcycle owners. When it comes time to winterize your bike you gotta keep the battery healthy. This little device was made for that. It has great functionality in that it recognizes the varies charge states and applies the level you need. It’s small and works with most motorcycles. It’s been a great addition to the garage.

I have ordered and used a number of this model for both vehicles and ATVs and they work extremely well. Long cord which helps for access. The gauge is easy to read. Flashes when charging till stable green and know battery is ready to go. If don’t drive a vehicle frequently this will save you money on keeping the battery working well.

I have had an older model for over 15 years on my ATV and am still using the original battery that came with the ATV and which should only have lasted about 4 years. The tender finally quit and so I got a replacement. Wonderful product.

Perfeito

Easy to use and works fanastic

This item is really for the U.S. market and was of no use to me as can not be safety used with uk power system.

Comprei esse modelo para manter a bateria da minha moto. Esse modelo é 110v(não percebi essa informação no anúncio) e eu precisei comprar um transformador(mais fácil que devolver o equipamento) de 220v para 110v. Mas tirando esse detalhe deu tudo certo.

These are used on our lawnmowers, tractors, and pickup trucks. The larger batteries take a long time to do a full charge if you need to with the Jr, but we use a higher output charger in those cases. In terms of partial charging like topping up and floating/maintaining, which is what we were after, this Jr model does the job. In the past we had some equipment that wouldn’t get used very often, especially throughout the cold Canadian winter and so the batteries would only last 2-3 years. Ever since we started using these maintainer products our batteries have been lasting 6-7 years. As soon as something gets parked it gets connected to a Tender, and the engine always fires right back up because of this. Considering batteries typically cost hundreds of dollars, the cost of these maintainers is well worth it. Our oldest Battery Tenders are over 12 years old and are still functioning, and only 1 has ever stopped functioning after a decade of consistent use. It comes with a full 12ft cord with a quick connector at about the 10ft mark, and both a separate 2ft clip or ring terminal cord. Both cords have replaceable fuses. You can hook up both to different batteries at the same time and just disconnect the quick connector to move the maintainer between them. The plug box is lightweight and doesn’t sag on the outlet and leaves enough space to use the upper socket. The cord has a medium flex and has a somewhat tough jacket, but isn’t built for being heavily abused. For the more technical buyer, this unit looks to hit a max of 14.5V and 800mA while charging and floats/maintains at 13.1V to 13.4V depending on the ambient temperature.
