Another flat battery on Brand New LC

[GR8Santini]

@basicxj - Nice concept.
Probably not that to mod a dual system up. One battery in cargo area & one under the hood. For those that have the open area inside the engine compartment behind the drivers side headlight (where air compressors get put), place a simple marine battery box & wire +/- battery leads over to the passenger side power distribution box. Might be easier than I make it sound.

I don’t get it.. My 2015 Ford Transit 350 has dual AGM’s that are now 11.5 years old, and STILL going strong. And yet Costco’s (Interstate brand) AGM only has a 36 month warranty.

I've gone thru two Optima yellow top AGMs on my 2014 Sprinter (not dual setup). But they get abused by most standards. Sit for long periods of time not getting charged, then get deeply discharged when used. I re-did the van's 12v system last spring and put in a trickle charger from the house system to the starter battery. Hoping to keep the new AGM going indefinitely now... we'll see!
