- Battery Tender 5 Bank Multibank Charger - 20 AMP (4 AMPs Per Bank) - Selectable 12V / 6V - Smart and Switchable 12V Multi Battery Charger and Maintainer for Automotive and Marine - 021-0133-DL-WH

I started buying the individual Battery Tenders and with two batteries I had it covered. Then the third and forth battery came into the operation so this 5 bank tender is the cat's meow. Organized and looking professional and functional to keep all our batteries ready for action.

good quality, fast shipping.

Well, can't go wrong with Battery Tender, but holy cow this is huge!!!

Have used Battery Tender for years on Quads, Harley Davidson, Lawn Tractor and Truck. Works great, delivery time was excellent and price was even better considering all the other on line prices....would definitively recommend

This was the perfect item for our boating, jetski battery needs. Able to maintain charge on several items at once.

The item was defective, only 4 of the 5 charging ports were functional. Customer support on the product was marginal at best, left several messages and no return call or email. On the good side, the four of five charging ports worked so maybe buy a trickle charger with six ports to get five working ones!?

I purchased this unit from Amazon. After using this on various cars and motorcycles, leads started to go intermittent on me. Only by jiggling them on the contact points on the tender would they make contact. Now only 2 of the 5 banks work. I took the unit apart and found that the nylon snap contacts for the leads are soldered directly to the master board with 2 delicate solder points. As the user connects and disconnects the leads, the nylon connectors snap together. Very flimsy way of making contact for a point that sees repeated usage. Absolutely no stress relief for the solder points. Poor design for reliability. It would cost a bunch to repair, then after use, would fail again. They should have placed a flexible intermediate lead to the disconnect points. Buy the individual units instead. This is NOT commercial quality by any stretch of the imagination.

Works good 2 thumbs up
