Anybody have a favorite place to buy replacement UPS batteries? I need at least one, and preferably three APC RBC7's. Onager's "replace my batteries NOWNOWNOW" alarm went off last night and it's sitting there blinking at me reproachfully. Either Mangonel or Ballista will need replacement soon as well, I suspect; I've only replaced batteries in one of the three UPSes since I bought them.
In fact, I still have the battery I took out of it; never got around to shipping it back. tsk.
ANYWAY. APC sells the battery modules for, like, $150 or so, but Froogle lists them as low as $37, so I wanted to see if anybody had a particular supplier they were fond of, that had decent prices.
