320 amp hour AGM upgrade for 8D batteries

Has anyone tried converting from Flooded batteries to VRLA for the coach batteries?

Any issues with mounting or performance?

We were our local battery supply store in Stockton Ca to pick up some cleaner and observed some work that caught our eye.

They had recently changed out some 160 amp hour telcom batteries and were reuseing them in a motorhome.

The telcom folks change out the batteries well before they are bad, it looked like 2 of these would fit where an 8D battery would go.

They are just a little taller and possibly longer by just a little bit, the coach being worked on had 6 installed and went from 600 ah to 960 amp hour capacity, and no more maintenance or acid spills.

They were used batteries so they may not be perfect but they were selling the batteries for only $60.00 each, for an AGM/VRLA battery that is Telcom rated that is scrap price.

Looked like they had a couple pallets of them, we got a couple just to play with, maybe add an additional battery under the seat.

They needed to build a special harness so the factory wiring was left stock, but it looked like factory when these guys got done.

They even would ship out a kit with the batteries and the cables if the customer pays for the shipping, so if they get more we can upgrade later when our 8Ds die off.
