I ordered these batteries for an APC SMT1000i Smart UPS. The batteries fit fine, came well packaged with very quick delivery and the terminals fit my existing UPS without an issue. The Open Circuit Voltage of the batteries when receiving them was also good. (12.9V-13V). The UPS had no trouble recognising them and after fully charging them I started to to a calibration/load test on them. APC's website say that brand new APC official batteries can deliver around 375 watts of power for 15 minutes. I set up the UPS connected to a 375 ish watt load and disconnected the UPS. I expected to only gain around 12 minutes of runtime from them and was happy that the runtime approximately matched APC's official RBCs at 15 Minutes! I recommend these batteries at the time being thanks to my very non scientific test that you almost certainly should not take as the worlds most accurate figures, but only time will tell how long they last.

Cheapest replacement UPS batteries I could find. Tanya called to let me know delivery would be delayed, they arrived in 3 days. Batteries work fine but only time will tell!

Fitted perfectly in my APC SmartUPS V/S 1000. Ran a power fail test and system held up for over 15 minutes as hoped for with no problems. Excellent value replacements for Yuasa NP12-12 batteries.
