12V 9Ah
I was looking for a 9Ah replacement pair of batteries for my APC BX1500 UPS. I chose this brand at AAA Security Depot because AGM batteries are supposed to allow deeper/more discharge/recharge cycles. I found that all these batteries are SLA or sealed lead acid, so that is not a critical feature. I did buy a third battery for another single battery UPS, so I could get a small discount. The package arrived earlier than expected on my door step within a card board box, covered in a thinly padded US Postal &#34;priority mail&#34; mailer; each battery was in a thin open plastic baggy, I'm guessing to prevent  the possibility of acid leakage damaging the other batteries. One of the F2 terminals was bent but easily straightened; if you use a metal screw driver, be careful not to short out against the other terminal. Double check your wiring before sealing it up; one of the connectors came loose and there was no output voltage - I used a voltmeter to confirm. If there is no voltage on a BX1500, the &#34;Replace Battery&#34; LED is lit solid and the alarm beeps every 2 seconds. Carefully read the specs at any battery site; I've seen several &#34;suggested&#34; batteries listed at a lower capacity of 7 or 8 amps - 7 amps is only sufficient for a lower capacity UPS like the APC BX1000.<br /><br />If you don't plan to replace UPS batteries soon, pull them out; there was a slight difficulty removing them after I had left spent batteries installed for more than a year - they can bulge with age.
