So 8 of those batteries together may yield 40 A/H of capacity. A standard
group 41 gives 60-65 A/H. So except that they may be free I don't see how
this is any type of upgrade. And have getting them all connected together.
Does the UPS work? Let it charge them. If one is open you will be able to
find it with a voltmeter.

Hi All,

So, in my never-ending upgrade spree of my vanagon I've come across a UPS
with 8 of these batteries in series:

http://bit.ly/QtprbR

It seems like the batteries might be dead and I'm thinking about charging
them to see if they will hold a charge. I'm not sure how to go about
charging them.

Should I disconnect everything and charge one by one or can I charge in
series?

Anyone have any experience with this?

They were hooked up to a UPS with a 240V 20A input so there's some
electronics that reside before the 1st set of batteries. Can I just
disconnect that and charge them with a 2A trickle charger?

I'm googling while I write this but I figured some of you might know.

TIA!

Cheers,
Harry
