Sears Platinum (Odyssey) AGM batteries 20% off

I have one of these.
They are MONSTER heavy. But cool that it is 100% sealed.
Sears also had a crazy warranty - it's like 7 yrs and 100k miles or something, they track it by your phone #.

but - beware - if you kill these batteries it is not so easy to revive them.
 
They're pretty tough to kill, though. I got 7 years out of my last one... and really, it probably died from negligence. Left it in the Bronco for a year or so.

I tried putting it in parallel with a good battery and charging it that way, but it wouldn't come back.
 
Nope. You have to trickle charge it at an amperage intended for an AGM battery.
I have completely drained mine several times, once winching, rest of the time from the 4Runner sitting too long, it has some parasitic drain/short.

Refer to Page 13. :flipoff2: Also note that they say 5% of the 20aAh rating. Figuring a 20Ah rating of a "normal" size Odyssey is 50-70Ah, that's in the ballpark of the 2-4A trickle charge settings that most any cheap household battery charger will do.

The trick is usually getting enough voltage to the battery to desulfate it. A lot of battery chargers only put out like 14-15V. You really need 17-18V in your bulk charge mode for it to work well. The battery controller I've got in the trailer now does something like this.
