Mighty Max BatteryML8-12 - 12V 8AH Replacement for APC Back-UPS ES 750 UPS Battery

Purchased to replace a APC Battery backup that was drained. I put in this new battery and it lasted a day before red light and beeping started again. I reused another old/battery from a different backup and that lasted a week longer than this new battery. I contacted the company and they are sending a replacement, honoring their 1 year warranty. I'm willing to try these again, as I never had any issues in the past. Thank you for your prompt response (though I didn't see the response on Amazon for a week) I modified my review from 1 Star to 4!

good replacement for APC. only difference was the metal tabs on this battery were smaller than the original. This made the install a bit harder but still doable.

This is my third battery for my 15 yr old APC ES 750. The original battery lasted about 10 years. The first replacement ML8-12 lasted about 2 years. If this one lasts 2 years that is $10 a year protection, not too bad these days. Batteries are a roll of the dice some last longer than others no matter which one you buy.

I now have to replace this battery, but it lasted five years so will buy the same model. Excellent value.

There much better than stock batteries. Backup battery systems come with cheap batteries. They never last but these last and have more power that lasts.

Keep doing good!

I have received two batteries from Mighty Max for my BE750BB, both arrived fully charged and ready for service. My impressions is that both are high quality. Though intended to fill my order neither battery received fit the physical dimensions of my BE750BB APC unit, not even close dimensionally, although electrically they had the correct voltage. The first battery was for a BE500BB unit, and the second I don't know, but neither was a physical fit. APC made two 750 models, the BE750BB and the BE750G, and the batteries that arrived here aren't for either of those. I have to hand it to Mighty Max for not only sending a second battery (at no charge), but also for fully refunding my money on the first battery received. While I will gladly return the two batteries, they have yet to ask for that or make it possible. APC may have helped in the confusion between these two models as to what is needed, but the point I want to get across is that in addition to receiving a quality product, you want to have post sales service, and I personally value post sales service as much as the quality product. Mighty Max is just such a company. While I didn't end up with the battery I needed, they did send two quality batteries, fully charged each in the sincere attempt to satisfy my requirement. I'm not out of pocket and my best advice to you is in addition to making sure you order for your specific model of APC (or other brand), that you also send a note to Mighty Max following your order supplying them the H x L x W dimensions of the battery you need. In many cases because there will be clarity of make and model that wont be absolutely necessary, but it might be helpful. As I said some confusion may have started with misinformation from the APC company who not only makes the APC, but is also a re-seller of replacement batteries (at about triple Might Max's price), and so APC is also a competitor who on some level may not see the neighborly value in helping Mighty Max market precise replacements. I withhold one star, because I didn't get the right battery, I give four stars and a recommendation to use Might Max because they stayed the course never quitting on me, and that's a value you can take to the bank.

Great way to shop
