12V 9AH SLA Battery replaces hr1234w

Measure your old 12 volt battery, these are 5.94 inches x 2.56 inches x 4.02 (including the terminals on top) If you get similar measurements, these will work for you There's plenty of original batteries this size with different ID numbers. they came in a wide variety of rechargeable devices, including UPS backup systems What they all have in common, is they store less power than these do I have 3 myself PE12V7.2 (7.2 ah) HYS1245 (4.5 ah) UN3-12 (3 ah) This last one came in my rechargeable portable air compressor, I have 2, a Slime and Campbell Hausfeld (same compressor,different names on them) As weak as the UN3-12 was, you can't get them with the measly 3ah anymore, the new replacements have been reduced to 2.5ah to 2.8ah,(even weaker) Replacing the UN3-12 with these 9ah batteries gives you 3X the storage capacity of the original and increases the run time and usefulness of your device. I highly recommend these batteries.
