I am looking at switching to a lighter-weight AGM battery (I'm considering the Deka EXT20L) and am going to need to get a BatteryMinder for it. In looking at the BatteryMinder website, I see they have a 2012 and a 2012-AGM. The 2012 model says it works for standard AGM batteries, while the 2012-AGM says it is to be used for specially sealed AGM batteries such as Odyssey. Does anyone know which model would work with the Deka battery?

Look at the Optimate line of battery tenders. Much more intelligent. I have several and thy are much better thn Battery Tender brand.

What is the best way of using a battery tender? I know some people leave them hooked up the whole time the car is not being driven; other people use them for 24 hours every two weeks or so. Is one way better than the other for prolonging battery life?

I've had 3 diff batteries on my 2 Elises.

I've used a Battery Minder Plus for that last 3 winters. Bought it with the 12V outlet adapter. Plug it in, leave it running - easy peasy.

Do it for my Elise and my Moke. They've been on tenders for 3 weeks. Stopped in this weekend and both started right up no issues.

Dealtran Battery Tender Plus.

I've used it with both the alligator clips and the accesory plug and no issues.

I have 4 BatteryMinders that I rotate among a dozen batteries about a month at a time. Just leave them plugged in. I've had them on batteries that tested dead, and a month later they were perfectly fine.

Another one here for the BatteryTender. I have a red top battery. I use it on both the Elise (with cig adapter) and my jet ski that's garaged in the winter....happy camper.

I leave my tender on all winter non-stop on my Triumph m/c with a sealed battery. No problem if you have an intelligent tender. Starts right up full power, even when very cold. I used to have to buy a battery for it every other year. I'm on year 5 on this one now.
