Two reviews here - most recent purchase was for a replacement to APC ES550G backup UPS.The battery is a snug replacement for the original, and takes a couple of minutes to fit. I noticed on reboot that my NAS (a QNAP) showed remaining time on the UPS as less than one minute even with a full 100% charge showing! The battery is likely fine, just the calibration. Same result when I installed Powerchute (Windows 7). Quick research shows a common problem - you have two solutions, and maybe have to do both.Step 1 - Recalibrate battery: basically, shutdown everything. Unplug devices from battery. Leave to charge to 100% (usually 8-24 hours) with no load. Unplug UPS from wall. It should now only power via the battery. Apply a load that doesn't mind suddenly losing power (lamps, monitors, printers). Wait for UPS to die completely. Unplug everything. Plug back into wall. Wait to recharge completely. Plug PC and NAS back in and look at UPS settings. You should have 30-40 mins of charge depending on the draw you applied.This didn't work for me... so I had to do step 2:Step 2 (optional): The latest (as of now) powerchute version 3.X has removed a key feature - resetting the battery replacement date. You have to get hold of a version 2.X of powerchute - its not on their website but can be found on their FTP server ftp.apc.com under /apc/public/software/windows/xp/pcpe/200 - you'll need to login anonymous. Although this says for XP, it worked on W7 64 bit - I just set the "compatibility" under properties of the file, to XP. Install software. Plug in the USB cable to your laptop/PC. Start software, and assuming it still says <1 minute power left, go to the Configuration, Options and you should see a battery icon next to "APC recommends ..." - click the battery icon to reset the stats. Then restart Powerchute (maybe reboot instead) and it should then show the correct runtime duration.Hopefully this helps someone else - why they removed this useful option, I don't know...Alarm BatteryBought this to replace the defunct house alarm battery on my Menvier TS590. It took all of 5 mins to replace. Taking the alarm panel off caused a "tamper" fault, but once the battery was replaced, panel put back, all I did was re-enter the main code and hit ENT, and it reset that fault too. Call out would have been £145.

Nothing to dislike - it does the job perfectly.

The unit I've put it in tends to overcharge a bit (DO watch the rated voltage folks, if you want these to last!)Lead-Acids are handy, if a little heavy - less fire risk than Lithium (always a plus for Fire Alarms!)They dont like being left flat for too long, but if you follow the instructions these DO last pretty well :)

I've used Yuasa batteries from my long-gone biking days to many years of alarms and UPS services. A consistently reliable product at a good price. My latest order of two of these arrived a couple of days before the expected delivery date, so my thanks to the supplier and couriers.

Excellent

Great batteries no problems here

Bought this as a direct replacement for the dead battery in my rechargeable work spot lamp, easy to change due to the speed connections, lamp charging & working in no time
