Hey guys,
One of the reasons UPSs use sealed lead-acid batteries is they are
located indoors. If you want to use marine or tractor (or regular car)
batteries, they should be located in the proverbial "well ventilated
space". Lead-acid batteries give off hydrogen and oxygen when charging,
a volatile mixture that will linger in any enclosure. I use
batterywholesale.com for replacement SLA batteries where a 4-battery
pack is $200.
For the manual, have you tried calling support at the current [no pun]
company? Sometimes real-time communication is best [again, no pun].

Hmmm... That's a great idea. Hopefully, the charging circuit works on
tractor batteries as well as the pricey SLA's specified.
And Mark G had the idea of looking for online manuals via
archive.org, also an excellent suggestion. Unfortunately, the index /
top layer pages seem to be in the archive, but little else. So far,
no manuals.
Thanks, to both you guys.

Hi
I prefer to use marine batteries. They are made in large enough
volume to be inexpensive and the deep cycle ones are more
forgiving of being flattened occasionally.
