    Our dealer recently had our MH in for over four weeks putting right (but mostly failing) the warranty problems I had identified. Over the time they managed to run our new AGM batteries so flat they could not even light an LED. They found the problem and have offered to replace them free of charge, but just how good is this battery type and have they been damaged by their mistreatment.

    AGM free............ I would bite your arm off. If I could afford them I would have them tomorrow. I'm sure there will loads giving you more good than bad points soon.

    Had our pair last year. They don't loose charge when standing idle, last a hell of a time compared to our old wet ones when in use and charge faster too. Very happy with them

    They are the best batteries in my opinion especially in the VRLA type. Only downside to them is cost in my opinion.

    It's another type of lead-acid battery, with all sorts of claims for better this and that, but at the end of the day ALL lead-acid batteries need very similar treatment and looking after.

    If the habitation loads had all been taken through a low voltage cutoff, it would have protected the batteries from serious overdischarge. Most solar controllers include this function but few use it.

    Replacing like with like would be the way to go, we have AGM in the Mercedes.

    Gromett: You can't get AGM in anything other than VRLA type.
