Bests & Worsts Reviews from Amazon

This is the second of these batteries i bought only because i was in a hurry and local homedepot and lowes stores were out and i do know better about buying batteries like this online as they almost always are old sulfated stock and usually half dead.And i was right.And of coarse when you buy these online from amazon and most other places you cant return so your screwed.First off I am am electronic tech so i know very well how to test the capacity of a battery and maintain it properly.I should have quit after the first battery but as i said i was in a hurry.Buy from your local store if possible that way if you have a bad battery they can check or at least exchange with no hassle.The first battery i bought would at least supply 150 watts of power for a 200 watt ups backup system without a instant shutdown of bad battery,which i could live with,so i decided to buy a second one and was hoping at least similar results but NOPE.It would not even have enough to start to supply 85 watts backup without instant shutdown.Also strange is that first battery had a manufacture date within 2 months stamped into it but second one had no date at all so im sure it was old old stock as they probably dont even know for sure..LOL...JUST A WARNING PEOPLE FROM SOMEONE THAT KNOWS ABOUT TESTING CAPACITY OF BATTERIES'''BEWARE AND MAYBE TAKE MY ADVISE...BUY LOCAL IN CASE...LESS RETURN HASSLE...still early but maybe seller will rectify..we,ll see and update.
