This compact 800 mA battery charger has all the charge characteristics of its cousin the Battery Tender Junior. It incorporates highly efficient surface mount technology electronic components.

It's tough, affordable, and a strong, innovative battery charging solution.

Perfect for all outdoor types of ATV's, watercraft,motorcycles, boats, or anywhere water is a threat.
Have this on a mower which only gets used occasionally; keeps the battery fully charged and ready to go
Got the battery tender 800 because its waterproof and high efficiency. i own 3 battery tender junior along with other battery tender accessories. the battery tender 800 will be great to have on hand to charge a battery outside if i need to. Great charger/maintainers and recommend these products. battery mart shipped the item fast and well packaged. thanks battery tender and battery mart. A++++.
Would be better if it pulsed and the plug side was longer. Does the job it was intended to do.
This battery tender does what i want. My car sits for a week at a time and when i'am ready so is
my car. Being a 1990 the car has some keep alive ckt that drains the battery when car sits too
long with out charging . This unit takes care of this for me.
I ride all year. But in the fall and spring I can't get to my shed because of the thawing, ice,
or mud. So I have to park my bike in the
driveway. Well the dummy forgot to unplug the
last waterproof charger and rode the 30 miles to work... They don't drag well.
The charger, as stated works outside most of the winter in all weather.
Great product. I ride all over the northeast and frequently end up riding in the rain. For the few times when I needed to give my battery a boost, its nice to it can be done in a wet environment. Just a great product that does what it is supposed to do.
To keep from adding an additional power source location I purchased a 25 foot extension . This also due to having boat on a lift in a boat house.
Will need to purchase a second unit when boat is put in storage for winter. But will not need all the connectors that come with the original.
