4-Bank Battery Tender is rated 4.0 out of 5 by 3.
Rated 3 out of 5 by from Great Product w/ One Exception Love the product, the quality, ease of use, etc with one rather annoying exception. The eye-ring connectors supplied with the unit DO NOT fit on side post batteries. You'll need to purchase something additional to hook this up if that's the case. Be sure to check how you'd attach it BEFORE you buy (assuming you'd rather not use the alligator clips)... It's annoying to find out after the fact that a great product is marred by a major design short-coming.

Rated 5 out of 5 by from Good device to maintain my toys batteries over the cold Colorado winter. For my toys that must be put up for the winter maintaining the batteries was a real problem until I purchased the 4 Station Battery Tender. Great product for maintaining multiple batteries using one centrally located device. I also purchased the 4 pack of 25' extension cables so all my stored toys are well within reach of the Battery Tender. I look forward to extending the life of toys batteries and saving the money I would have spent to replace them more often than is really needed if they are kept fully charged over the winter months.

Rated 4 out of 5 by from 4 bank battery tender If you have multiple motorcycles like our families have, this is the bomb. For the cost of 2 batteries, the four bank tender will save us money and guarantee your machine(s) will be ready when you are.
