Replacing battery(s) in MGE pulsar EX15 UPS
 

I have an MGE pulsar EX15 UPS (uninterruptable power-supply), and I
think
the battery or batteries inside have gone bad.

Unfortunately this UPS does not appear to be designed with a
user-servicable
battery. That said, has anyone replaced the battery on this model or
similar
model UPS?

I've replaced the battery in several APC Back-UPS Pro 650 UPSs, but
that
model seemed to have been designed for user-replacement of the
batteries.

Also, does anyone know the size/type/voltage/quantity battery(s) this
UPS
uses? I'm guessing it uses either a 6V or 12V sealed lead acid
batteries
as that's what is typically used, but it'd be nice to know specifically
the exact specifications so I can price a replacement to see if it's
worth
the cost of replacement.

If you can work out the battery rating and voltage, it is possible to
substitute adapt on to the UPS with a gel cell battery that is close to the
original.

Yeah, I don't imagine finding a replacement battery will be too tough.

I figured I'd try to solicit information before I open the beast up on
the chance that someone else has owned one of these machines and has
some
words to the wise that would save me some trouble or time. I think
that
opening up a piece of equipment without any foreknowledge can lead to
trouble.

I just cracked my MGE Pulsar EX15 open. The exterior "lid" was held on
with seven Torx T-10 screws. With the case off, I studied the battery
arrangement. Getting the batteries replaced properly and safely will
be a challenge with this particular piece of equipment and I'd
recommend leaving it to someone with electronics repair experience.

The machine appears to have four batteries. I removed one battery.
The label says "GP 1270 F2" "12V 7.0Ah" "CSB BATTERY CO., LTD" "MADE IN
TAIWAN".

I'm not certain, but it appears all four batteries are connected in
series. When removing batteries from this machine, I'd suggest
labeling the wires as you remove them - otherwise you might not get
things back together properly.

After doing a quick Internet search, I'd estimate the cost for a set of
replacement batteries to be around $120 to 140 (USD).

One more note about the battery ("GP 1270 F2") I removed from the UPS.

The approximate dimensions a
2 and 1/2 inches wide
5 and 7/8 inches long
3 and 5/8 inches high (not including top terminals)
