Mighty Max 12V 9AH SLA Rechargeable Battery - Replaces hr1234w

Charles McGehee: Followup comments: These batteries have been in service 24/7 for a week now. Very Impressive batteries. I'm using them in a Cyberpower 1500 pfclcd model U.P.S. and they are working extremely well. They are holding a good solid charge.

I like the speed of delivery. The batteries arrived early and very well packed. These are used in my PC backup power supply. (U.P.S.
These arrived fully charged. They are priced very low compared to other vendors.
In fact I'm writing this review on a desktop PC running on these batteries.

So far so good. Now let me see how many years they last. My last set ran 8 years.
Thank you for delivering what you advertised!

✨ H A P P Y 💖 S H O P P E R ✨ ✌😊: I replaced my UPS batteries with new 9AH batteries a few months ago, but I am not seeing a significant increase in runtime. I performed a runtime estimation by discharging the new batteries to near zero capacity. The result was 72 minutes estimated runtime. I did the same with my old 7.5AH batteries when they were brand new, and I got 69 minutes. I used the same devices during both runtime estimations. I repeated the estimation again and got 73 minutes. I am wondering if I actually received 9AH batteries. At least, the new batteries haven't degraded noticeably since installation three months ago.

NYCSteeler: These batteries are a perfect replacement for the dead batteries on my Cyber Power 100VA UPS - the terminals were the exact size and I did not have to make any modifications; it was a simple plug and play. I did use strong packing tape to unit the batteries like the old batteries were as the original tape was no longer usable. It was a simple plug and play and i was up and tunning within a few minutes. Fully charged them and they work just fine.

Big Mike: After 5-plus years, my CyberPower 1500VA UPS stopped working. At first, the equipment plugged into battery-backup outlets would occasionally shut down and restart. Finally, the battery-backup outlets stopped working altogether. I checked the batteries and they were dead. I tried to charge them with a 12V auto battery charger, but they would not hold a charge.
From what I read on the Internet, the OEM batteries (HR1234W) were rated at 8AH. These batteries were rated at 9AH which is better. They were described as an exact replacement for the HR1234W batteries which is why I selected them. And they were well-priced. I was pleased that they were delivered to me in 3 days.
It was quite easy to replace the batteries. They were almost fully charged when I installed them. I turned on the UPS overnight with no load to top off the charge. After that I plugged equipment (3 PC's, cable modem, and wireless router) back in and I was good to go.
Yesterday, we had a severe thunderstorm in the area and the power went out for 20 minutes. All the equipment stayed powered up without a problem so I know the batteries are working well. That's the main reason I have the UPS - to prevent...
