Battery tenders
Thinking of getting some battery tenders to keep a few of my vehicles maintained in storage. I have some concern about the possible risk of fire as a result of an electrical malfunction. How safe are these devices?

The Battery Tender brand is expensive at $60.00. I have (4) Schumacher battery maintainers that I bought at Meijers on sale for about $25.00 each. I use for boat, car, lawn tractor. They work great and easily pay for themselves becuase they extend the life of a battery.

Hi C.
I thought about this a lot because I have one in the mercedes while it is stored. Basically.... an AC to DC converter with a step down. If it is going to fail... it would most likely fail in a way that would result in an eventual open circuit. Even a short in the tender would imo cause an open. I don't see your battery coming in direct conact with the ac, no matter how it failed. I would say worst case scenario, if your tender fails, your battery fails. I can't drum up a case in my head in which your car or the building would burn.
I have had one for 20 years that I bought for a motorcyle. Maybe one amp or a half an amp.
It was like 15-20 bucks and it still works. Have used it on everything, and have even used it on the boat while the boat was at the dock.

Use it on my bike, and just ordered a 4 banger for boat batteries. I think they work great, they keep the bats from sulfating the plates. Just my .02
