Mighty Max 12V 8Ah UPS Battery - Replaces 7Ah 28W BB Battery SH1228W

copack357: I installed it in my CyberPower UPS. The UPS didn't indicate any error codes. I'm not sure where to recycle the battery that was replaced, but that's my issue to figure out.

Danny: Lasted 2.5 yrs. I thought batteries were supposed to last 3-5yrs. I did have a few outages last summer and probably the summer before as well. But, still, that doesn't seem quite enough to warrant the short lifespan. It's not as if I let the battery completely drain each time. But 2.5yrs for about $20 is still a pretty good deal.

I can't remember what the installation experience was like last time. But, for my new battery, installation was a little bit of a hassle. I had to use needle-nose pliers to adjust the black wire's position while battery was in place. And, since it's behind the red wire, it's best to wait until after you adjust the black wire before you attach the red wire, which will also require the needle-nose pliers.

D. L R: I have the Cyberpower 600VA UPS and it fits exactly like the vendor says. One installation tip I would give is the "old battery" is difficult to remove the leads to the battery so I suggest getting a small screwdriver and hammer and placing the screwdriver where the lead would come off, tap gently and it will come off easily. I also suggest putting a piece of masking tape on the side of the new battery that faces out marked SH1228W battery. This is not marked on the new battery!

Update: The battery is fantastic so I bought two (I have two Cyberpower 600VA UPSs). The second one (the newest one) was actually hard to squeeze in because the leads on the Cyberpower are just a little too short. This one require putting one lead on and pulling it snug with needle nose pliers. I think Cyberpower doesn't want you to replace the battery. I used the same techniques as above to put on the second lead.

Update 7/13/21: I just purchased the third time because my Mighty Max Battery failed in just shy of two years ( 1 week away). I assume this battery has a 1 year warranty so I didn't complain but bit a third time (I do have two Cyberpower UPS's. I think the ease of replacing the...
