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.

I have this battery installed in my Uninterruptible Power Supply for a couple of months, so far no problems. The only problem I had is the posts were a bit smaller then the Original Equipment Manufacturer battery. After a couple of minutes of modifying the terminals to keep them on the installation, everything is working great. I will definitely purchase a couple for more for other Uninterruptible Power Supply's that require new batteries. Much less expensive if you have to purchase Original Equipment Manufacturer batteries from the manufacture. 9/8/19 3:25AM

[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.

The battery that came with the ES 750 finally failed after 10+ years. It took several hours of searching for a replacement battery. The physical size had to be the same, the electrical performance, etc., for a battery to be used in what is now a discontinued UPS. There were a lot of options out there that might have fit the bill. After down selecting, I thought this battery to be the best bet for the price and placed my order. It was delivered quickly, was easy to install and is functioning well.

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.

I can't say anything about the quality, it has only been in use for about a month. But it does work! The problem, and the reason for only gave three stars is that it is much smaller than the original battery. Would I buy it again? Yes but only because I could not find an exact fit and it does work.
