What he said. I am very curious now as to what it was listed as. 12 bucks a lb? Whoowee!

I am wondering if it was an error on the yard/cashiers part.

I would second the above. I know for a fact that you can replace the battery with a regular car battery and they work fine and can increase life by 4-5 times or more of the UPS. I have done so myself. You and also stack multiple batteries together and increase the lifespan further. Just keep in mind there is a gas given off by car batteries when they charge / are heavily used. This mod is best performed for use where there is good ventilation.

Also, check the body on them. I have found a lot of aluminum in them. I average about $2.50-$5 each out of them depending on size, age and current prices.

Something to keep in mind is if it is only the batter that is shot, most will still work as a surge protector / power strip anyways. They just wont keep the plugged in items on in the event of power failure.

Morning all. Scrappete being your a senior member so In no way am I saying your wrong. Id say that $12 dollar price was for like 40 pounds of agm/gel batts at .30 c a lbs. At my shop I only pay over a quarter to dealers. Thats a good price for batts. WHen I ship batts two the major end users here in the Northeast (rsr and NewAlta) they say they hate agm/gel because they mess up their pots. Flooded lead batts are water (if dead) lead, little tin, antimony and plastic. That stuff smelts fine I guess. Adding pallets of agm/gel and flooded may be a thing of the past because they are harder to refine.

FUnny things a good agm gel battery has a commanding price.. Whats a good auto worth..one a few months to year old $30 bucks. The agm/gels I get about a dollar an ah. THe ones in most apc units are 12 ah usually, sometimes 6ah or 18 and 25ah.

Your transformers usually bring the same $$$ around >30c lbs. Around here. Merry Christmas folks.

My buyer buys the boards as low grade.. Not like yellow or white but green low grade. Just a board of copper, copper bearing, al, heatsink and caps and resistors. Maybe a few transistors one ic chip maybe.

So I think. Im a newbie hit me over the head if I ramble to much.
