battery choice
Hi, I am in analysis paralysis. I will be purchasing AGM jars. Here are my two choices: AGM L-16 Surrette 400 amp-hour six volt with 0.145 plates cost $520 plus tax and shipping Four are n...

Pretty sobering stuff about AGMs wanting such high charge currents.
Thanks to all for the links and info.
Need to rethink how best to expand the battery bank of our solar-only system.
AGM batteries do not "want" high charge currents.
What you can do with them is provide high charge currents (at the necessary voltages) and they will take indeed take/absorb the high currents. Under these condtions they can therefore be charged faster than wet cell batteries IF you have the high capacity charger to do this. AGM batteries can be charged this way because of their very low internal resistance as compared to wet cell batteries.
Our RV 's AGM batteries have seen only low charging currents for years because I do not use a high capacity charger on them ... other than just the engine alternator between campsites. Otherwise they only see 5-20 amps charging currents while camping.
