But you can deplete them double what SLA batteries will tolerate. That
makes them 50 cents /watt-hour.
Then they will last for 2X cycles of SLA batteries. That makes them ~~
25 cents /watt-hour.
Guess that's still high...

Interesting.� First place I checked was about 10 cents per watt hour.�
I wonder if you have to have a special charger or if you can just
float them like a regular AGM battery.

Need to build a 2 kW UPS for my server rack at my office.
Eltek/Valere rectifiers for sure.
Not sure what inverter I will go with yet.
Gonna run 100% inverter with a transfer switch in the event the
inverter dies.
But what is the best value for batts these days.
I see Rolls at 13 cents per watt hour.
Trojans for 16 cents (but they have ribs and a reservoir tip).
Got a quote for absolyte types for about 18 cents.
What else is out there?� Truck starter batteries can be had for 10
cents but I doubt their longevity.
