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.

    Jerry G.,


    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 are:
    2 and 1/2 inches wide
    5 and 7/8 inches long
    3 and 5/8 inches high (not including top terminals)
    3 and 7/8 inches high (including top terminals)
