Hi, Trying to charge my 80AH AGM 'S with my solar panel. An 80 AH lead acid will charge quickly to the 14.4v panel regulator cutoff setting, but my AGM's will rise to 13v within 10 minutes and stay there for at least 3 hours. I also am getting the same result from my AGM charger Charger specs:Battery 7-Stage Desulfator Ultipower 6V 12V 1A 2A 3A 4A Smart Charger 4 AGM GEL Battery 7-Stage Desulfator ( 352050613881 )
Battery specs:12V 80AH AGM Sealed Lead Acid DEEP CYCLE rechargeable Battery Caravan Camper ups 12V 80AH AGM Sealed Lead Acid DEEP CYCLE rechargeable Battery Caravan Camper ups

I have looked at sites such as " Battery University "but still need more education. My concern is that I may cause damage by leaving them for such a long time. Are the batteries, the charger or the operator at fault?:confused:

Thanks for the replies with the blend of old & newer members. My Suzuki carry has 7 80 AH AGM. Each is charged individually using the AGM charger or the Solar Panel:-RICH RS-M60 60WP.At present usable sun is from 7AM to 6.30 PM (EDST.AU).It seems I am expecting too much from this panel,but it certainly is helpful with the amount of sun available at 31 latitude. The suggested site was helpful with a good explanation of why the mppt controller gives more charge than direct output into a battery. Thankyou.
