another source for agm batteries
Hi, It's time for me to consider replacing four of my batteries that are now 8 years old. I came across this on Amazon. Any one have an opinion on this company? http://www.vmaxchargetank.com/...

1. Any truth to AGM's REQUIRING high charge rates to survive?
2. There are some Universal's here that work out to $1.76 per amp-hour http://www.batterystuff.com/batteries/rv/#a8830
1. No,.. maybe? See 2.
2. Here is your grp 24 battery at $1.73USD per AH.

The mfgr/dealer/distributor http://upgi.com/Themes/leanandgreen/images/UPG/ProductDownloads/45821.pdf.
It shows a spec of:
Control of 14.5 - 14.9V and,
Float of 13.6 - 13.80.
I have no idea what control is or what happens in the gap between 13.8 and 14.5. At the bottom they say cycle use they say almost the same with 2.4-2.5V/Cell of 14.4-15V. Also no mention of temp comp.
I know you run a 2500W inverter. Take a look at the Constant Power Discharge Characteristics Unit Watts (25°C, 77°F) table. You can convert inverter minutes into bank size. E.g., if your inverter has an 11.1V LVD, you could run a 1749W microwave for 10Min.
