testing of

the battery or periodic replacement were the two favored approaches.

Load

testing being the easiest and least expensive if you had a LOADing

device.

I notice in the DAMARK catalog a 100 amp battery load tester for

$19.99

tests six and twelve volt batteries and I have ordered one.  If

anyone else

is interested the part number is  B-40440-735122 and the web site

that it

can be ordered from by catalog is www.damark.com  if interested.  No

vested

interest in the company or product.

Good morning Ed,
Please tell us your evaluation of this battery load tester.
Yvon.

I use an old car headlamp (around 12 amps) to test with. Amp hour capacity
(of lead batteries) is very dependant on rate so the load should approximate
the actual drain of your systems to give accurate idea of how long battery
will hold up in alternator out condition.
