Typical great Battery Tender performance
Lives up to my previous experience with the Battery Tender brand: but works with either 6 or 12 volt batteries and both charges and maintains them. This is relatively new, but if it maintains battery health for years st a time with infrequently used auto batteries as prior units it will be an ideal solution to battery maintenance in infrequently used batteries.

Works and easy to use
Easy to understand instructions. Unit has a long enough cord thankfully. Do wish that the clamps were slightly bigger to attach easier to battery terminals. Otherwise great unit I recommend.

Works like a charm. Charged my 6-volt batteries!
It works great and charges both of my 6-volt batteries. For large batteries like that, make sure to unplug and plug back in when it stops, by default, if your battery takes longer than 24 hours. It has a built-in stop after a long period.
