I need some opinions on a non-aviation issue. I use a B&C RG battery in my airplane and when I chenge them out I keep them for other uses. One use a 12v Superwinch winch in my house to run a dumbwaiter up and down and I keep the battery charged with a Battery Tender. OK, here's the question...will the Battery Tender be damaged if I leave it connected when I'm using the winch? This has me scratching my head. Bob, care to chime in on this one? I'm just now setting up my circuitry so if it needs to be disconnected I can set up a relay that will disconnect it when the winch is active.

No, you won't hurt it. I'm not aware of the Battery-Tender
response to a discharge event.
I'd not explored this characteristic with the Battery
Tender. I went out to the mess-shop and stuck a load tester
on a car battery that was being "Tended". 100A for 10
15 seconds. The 'charge' light came on and it appears
to be going through a normal charge/top-off cycle.
That's what I would have expected but had never done
that experiment.
This has me scratching my head. Bob, care to chime in on this

Not necessary. If you've not yet bought a B-T,
consider a Schumacher 1562 for $20 delivered to
a local WalMart store. Twice the output current
and about 2/3 the price of a B-T.
Whoops . . . I see some B-T's offered for $26 with
free shipping. They're feeling the pressure. B-T
performs as advertised; the 1562 is twice the snort
for less money.

Thanks Bob,
Actually, I have a 1562 that I keep on my airplane battery which replaced
the B-T that I'm using for my winch battery. I tried the B-T on the winch
battery with the winch operating and everything came back up to a good
charge. Whew, now I don't have to screw around with a disconnecting relay.
