12V 3.4AH Sealed Lead Acid (SLA) Battery for WP3-12 Backup

Battery arrived in excellent condition and appears to be brand new as described. Installed battery in my APC 350ES UPS and fit perfectly and functions as expected. Unit worked during a brief power outage (a few seconds) the next day, so I have no reason to doubt this is an acceptable APC replacement battery at an excellent price

I purchased it for battery replacement of APC BE350. It uses Kung LONG WP3-12, and this battery is supposed to be compatible.

I pulled out the old battery and put the new one I just received in the case. Then I realized the battery cover does not fit well. It can still seal the case and make battery usable, but the cover protrudes from the case just little bit, like 1/8 inch. It made me little nervous about the compatibility.

They're visibly identical, but maybe hight is little higher than WP3-12 or maybe the edge shape might be different. In fact, BE352 battery cover edge has extra thickness area that might be specifically designed for the edge to settle down the battery in the case.

It's not perfect fit but the battery itself is working fine. I tested few times by unplugging UPS and it does what it supposed to do. So, it's just minor annoyance.
