No. I use Duracell AGMs from Sams. As for charging - yea, AGM should use a proper charger. The one in the dragster has been in there 3 years and it gets treated very badly. Hammered on the track, running fans and big water pump while getting hit with 40A burst charges for 10~15 minutes between rounds, then off the the next round. Down track it only gets support from a mini 50A alternator. It's about out of warranty and still doing just fine. It does get to see a proper support charge between races from a nice Schumacher. But at the track its a big conventional don't-care-what-battery 2, 10, 40, 100, 200 charger. So they ain't that dad gum picky. Door car uses an old Optima that barely works, that one would be gone except the big F-350 asked first. $170 more or less each, way way cheaper than Opti-crud.
