Keep an eye on that thing. DO google the SmartUPS 700 for experience stories.
If the batteries ever significantly discharge (i.e. more than a few minutes
off mains), I highly recommend you put new ones in rather than trust the
used ones, based on my experience. Mine is off line and scheduled for
destruction and recycling.



I'd buy it. Nothing that a few mods can't correct.

Just got 'em (via eBay) -- "Rhino" brand; about US$16 each, including
shipping. Look good, and hopefully will work well! Best retail
price
I
saw, plus shipping, was about $32 each.

I'll check next time. My last set was local and in between those
prices.


Good! There's only one batteries-only dealer here in town, and it is
about a 15 mile round trip. So add ~$3 for gas ...

Installed the new batteries yesterday. As warned, the lugs were
smaller, so I had to crimp-down one connector slightly to get a tighter
fit.

Also, the last connection was shocking! Actually sparking -- one huge
bolt, and I'm glad I wasn't in its way. There's a good-sized capacitor
internally to the UPS, and my guess is that the batteries needed to
recharge it upon connection.

I just replaced the batteries in a non responding SMART UPS. What a
stupid
UPS.
The batteies were for a 1500 watt unit, heavy.

I don't think I'm quite following that ...

What, that a smart ups can't say the battery is ka putt.

greg

Well my Smart-UPS 700 can tell me that the batteries are kaput. Third row of
lights left to right. Bottom one is the "Battery Kaput" light ... In fact
the diagnostic lights tell me a lot about what it's doing, so I wouldn't
describe that particular model as "stupid".

I bought a couple APC Back-UPS XP 1000's in 2004. One is on my A/V
equip in my living room and one in my office. I also have a Back-UPS ES
350 on my DSL modem, wireless router and Linksys NSU1 network storage unit
bought around the same time. I've never had any problems with those units.
The 1000's self test on their own at regular intervals and the 350 still
runs for 45 minutes with the equivalent load of a PC with two hard drives
minus a monitor. Trust me I've had my fair share of failed APC units but I
have yet to figure out why some last for a year or so and others seem to
last forever. If I had to guess I would say it's the quality of the
batteries if the unit just sits there not being called upon for backup and
suffers an untimely death.


It may be that the store doesn't rotate stock, and the battery
deteriorates before it's sold. I have about 20 that need new batteries,
but they were all over five years old when pulled from service. They
were all from a high volume user who buys directly from APC.

IME the difference is more to do with the battery (re-)charging and maintenance
charging regime. Too often the manufacturer's arrangement is designed for
maximum recovery rate (minimum recovery time) after a discharge, and they also
tend to float them at a high terminal voltage. Almost without exception, every
failed UPS I have checked had cooked SLA/VRLA batteries. That cooking came
about at the hands of the charger, not the internal temperature of the unit.

soapbox It is similar to the fate of Lithium-Ion laptop batteries. The
appliance manufacturer's objective is maximised operating time, so they charge
to 4v2. Charging to 4v1 would give something under 20% less usable capacity,
but double the cycle life. The manufacturer would rather quote 3 hours
endurance than 2.5 hours, so he configures the machine for maximised sales spec.
The user picks up the tab later. /soapbox

You might try to charge the batteries with a conventional charger or
variable power supply for an hour or so at a low current then replace
them in the unit.

Its unlikely that it will work.

It does; I've done it many times. An electronic charger, one that
monitors the charging current, is needed, and if you have one that has a
setting/switch for "Maintenance Free" (i.e. sealed) type, so much the
better.

You don't need to aim for a full charge; just enough to allow the UPS to
initialise, then it will continue charging as required.
