ML8-12 - 12V 8AH Replacement for APC Back-UPS ES 750 UPS Battery

Perfect fit for my sprayer. Excellent price.

It works great and it is easy to install!

This was the best price for a replacement battery for my backup device. Shipping was free which is rare for a battery this size and I received it in three days, Overall a great experience so far and only time will tell how it performs its task.

The battery was shipped quickly, arrived charged and working. I measured 12.4 V on it. Great product, nothing to complain about.

Battery does a good job. My second purchase for my UPS unit.First didn't last a full 2 years, so I added the extended warranty hoping it will provide battery 3 at a reasonable price.As other review suggested, the APC terminals did not seem to be an exact fit, so I will contact seller with question about adapters.

[Original post] Back-UPS ES 750 UPS indicated low battery status right after the installation of this item. I sent an email to the seller and update here if they accept my request to take the item back. [Update and star level upgrade] The seller sent me a replacement that has been functioning properly but still charging energy.

I found a UPS at a thrift store that was in pretty good shape, worked just fine, took it home and a few months later it started tripping itself and beeping every other day, I assumed the battery was the issue - must have gone bad. Looked around for replacements and this was the cheapest one for my model (APC UPS ES 750)It fit right in the slot, powered it back on, and has been working like a charm ever since (at least a month or two by now) no more beeping! i'd recommend this to save some money and get more life out of your UPS without getting a new one

Definitly not a direct replacement…The terminals were smaller than OEM … with that said the size of the battery was correct and with a little pinching on the + cable and ingenuity on the – cable I was able to get it to work. Only time will tell if it lasts like OEM.

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.

This is a battery and it is just to soon to determine if it is truly a good bargain. But as of now it appears great.
