Hi all
Currently have a 110aH flooded Numax leisure battery connected to my starter with a Durite split charge relay.
Installed it 3 years ago and it's been okay, but not great. Within a couple of years the battery couldn't power the fridge through the second day, and now only reads 12.3v resting voltage. Clearly sulfated and on its way out.
My alternator charges fairly consistently at 13.9v, so I'm looking at upgrading to an AGM, charged through one of the new Adventure Kings 25a DCDC chargers to get its bulk charge up to 14.5-14.7v, and then maintain the float at the correct reduced level. I'm hoping a few hours driving each day will get more juice into an AGM with a DCDC than I was getting into my flooded battery with a simple voltage sensitive relay.
My issue is the only place I can fit an AGM is under the bonnet. I know heat kills all batteries, but apparently AGMs are more susceptible. The space for it is behind a headlight, on the opposite side from the turbo, so one of the cooler areas, but still, I'm concerned I'll kill it fairly quickly in the engine bay.
Can anyone here who's fitted an AGM in the engine bay share their experience? Not sure if I'm just concerned for no reason.
Thanks
Owen
