AGM battery maintainer.

I use this on the SL500. It has two batteries, 1 is AGM:

I also have one of these but I don't use it for my AGM anymore. The only reason is I have the larger CTEK 7002 for my Walmart H7 AGM and an Odyssey 15 amp (made by CTEK) for my Odyssey batteries. I use the MXS 5.0 for my wife's flooded.

11.5 years is pretty good for any type of battery. My best was a little over 6 years. Best I ever got out of a Harley brand new battery was a hair over 2 years. I'm sold on using battery tenders

I've also had 12 years out of the the last two car batteries but keeping them charged is only part of the equation. I'm in a cool climate and no one would expect to get that sort of battery life in a hotter climate. Needless to say I must be doing something right so I've bought pretty much the exact same AGM battery as a replacement. The bike is old with zero current draw so that's how I get away with not having it permanently hooked up to a maintainer.

That is the exact charger I have. In fact I just completed the annual AGM Recondition mode on my motorcycle battery yesterday. I have three CTEK chargers for various machines and they are excellent.
