[QUOTE="keep_hope_alive, post: 8121279, member: 576029"] AGM is Absorbed Glass Matt. it is a type of sealed lead acid battery (also called Valve Regulated Lead Acid or VRLA). this battery type is more robust, and doesn't require you add water. it also performs better. I run a Sears Die Hard Platinum Group 34/78 (dual side and top posts for easy aftermarket wiring while using factory battery terminals). This comes with a 4 year replacement and then another 4 year pro-rated warranty, better than anyone else. they sell for $200 at Sears. there are others like it with shorter warranties. look for Reserve Capacity (RC) when comparing batteries. replacing an alt may be easy, may be a PITA. depends on the vehicle. Quality Power in CA is one source. Ohio Generator is another. Budget $300-$400 for a good one). it requires upgrading wiring associated with the charging and grounding system (Big 3). this is tedious as it means you are adding thick wires to an engine bay. make a mistake or have your wiring fail and you are stranded. it's not hard, but attention to detail and good wire termination methods matter. I detail my process in my build log also. [/QUOTE]
