Caravan & Camper Battery Charging Feedback

that will do it just takes longer so Im told anyway

Have you got specs on the charger.

You need a good charger so the AGM dos not build up sulphation.

If you run the battery down to 50%, you need to replace 60 AH. Even assuming 100% efficiency, that will be 12 hours of charging to fully charge with a 5 Amp charger (with no load). If you are running a fridge or other stuff, it will take much longer.

Being a 5 Amp charger, I suspect it is a cheapie. You really should invest in a reasonable quality multi stage (smart) charger.
Most AGMs can handle high charge current, so you can do the maths yourself on charge time v cost of a bigger and better charger.

Might cost you $200 or more (depending on size), but it is money well spent. You will get the best out of your battery and the battery will last much longer if you are charging it correctly.

Simple rule of thumb is the charger should be able to deliver at least 10% of the batteries amp/hr capacity. ie 120 amp/hour battery should have at least 12 amp charger. Bigger is better. Get a 20 amp three stage charger. Xantrax is probably the best on the market. Ring Derek at ABR and he will have what you need. I have 2/ 105 amp hour batteries in my camper and have a 40 amp charger. Your 5 amp hour will take too long to charge the batteries.
