[QUOTE="Ridge Runner, post: 610044, member: 3775"] MasterVolt State that the Maximum Rate of Charge for AGM Batteries being 30%, I said a nice balance would be 20 to 25A, Again MasterVolt Say Between 15% = 19.5A to 25% = 32A, So like you I also said up to 20% which = 26A, Jaros's 10A Charger is "Only" 7.6% of 130Ah which is why I quoted him a Charger between 15 to 20% which is around the same numbers you just Quoted. IF an AGM loses around 5% +/- of its charge per month then his charger is not big enough. [u][b]A Classic Example of Lead Acid Vs Lithium[/b][/u] Note that AGM's are also Lead Acid Tech be it better than standard lead acid. The Minelab GP 3500 uses a 12Ah Lead Acid Battery And on Page 10 of the Manual it states that it takes up to 24 hour to charge a depleted Battery, The GPX 4800/5000 uses a 9.2Ah Lithium Battery and on Page 18 it States it takes up to 5 hours to when Depleted/Flat. If the GPX battery had 12Ah capacity like the GP Lead Acid battery then it would still only take 6.52 hours to charge OR 6hrs 32 minutes Vs 24 Hours. A 130Ah AGM has 67.5Ah of useable power before it hits the safe level @ 50% An 84Ah Lithium Battery will give you 67.2Ah at a DOD of 80% and it only weighs 10.2kgs. My 80AGM = 22.9kgs OR 2 X 60Ah Lithium Batteries will give you 96Ah and only weigh 7kgs each = ( 14kgs ) [/QUOTE]
