Trojan t-1275 vs Signature series J150 RE
Before winter, I need to get a dedicated flooded house battery, my Northstar AGM-27 has been working hard as both house and engine battery for the last 4 months, and I want to return it to engine star...

Hi Landy,
I can't find the post about a limit of 23 amps. I did find a reference to 21 amps.
I surmise the telecom battery has thicker plates--and that is no bad thing for a deep cycle battery. The trade off is slower charging rates.
The other known difference is that the telecom jars are not a starved acid situation. That makes them a tiny bit more forgiving of not reaching 100% state of charge. Perhaps it affects charge rate too? I do know the specific gravity is 1.30 vs 1.275 for a Rolls-Surrette.
Your situation is a bit unusual as you wish to go with just one house battery. Most folks have 2 and with 4 I've seen 96 amps going in (briefly).
I'm getting different charging rates from different charging sources. The strange part is that the batteries seem to recharge faster from the alternator than from the Magnum inverter/charger. Strange because the amps going in from the alternator are lower than what the Magnum says it is providing. Strange too, because the voltage coming from the alternator is lower than the Magnum. Perhaps the Magnum is lying? I have no easy way to check that.
