Someone is selling these and they appear to be about
a group31
size battery.



MCG-120P 110 AH Gel Technology SLA Solar
batteries



As some one who has a 2kVA UPS at work full of SLA
batteries ( I
think each pack has a dozen of those 12v 9Ah SLAs in
it), the
batteries are usually specially designed for the
application where
they spent most of their time 'floated' and only
occasionally
cycled.

 The plate construction is not optimal for a traction
application
where they are often cycled at high currents.



I'd check the actual battery specifications
carefully.
