ML9-12 - 12 Volt 9 AH, F2 Terminal, Rechargeable SLA AGM Battery,Pack of 1

I am using 24 of these batteries at this point and about to invest in 48 more so. I have tons of equipment, and anything worth a darn is behind a UPS for clean power and to survive the occasional blip in power. In the last decade, I literally haven't replaced a power supply in anything at all except a TV once because I took a surge through the cable line I forgot to protect. The clean sinewave coming off of a good UPS ensures me maximum life from power supplies and other delicate components, protects my equipment from surges, and at the heart of it all is the MightyMax battery. I've been using the ML9-12 for all my UPS 650, 600, Network 40, and similar gear. I even build my own packs for larger installs like my 2200s and 1500s. MightyMax is the best battery money can buy, performing well over it's cost point. Don't buy expensive batteries from the UPS manufacturers. Yes, those batteries are great, but you can save money and not skimp on performance using MightyMax batteries. I have done extensive testing, being I'm a geek like that, and here is what I have found: 1. They really are 9AH, just a tad over. With a lot of testing, I am getting on average 9.6AH out of these batteries. I have never gotten under 9.2 and never more than 9.9. I have had other batteries claim to by 9AH and I get mid-8s which is horrible and deceptive. Not with MightyMax, whatever it says they are, they are. 2. They age really well. These batteries age well for their price. Realistically most cheap UPS replacement batteries last a year to 18 months or so and you replace them. The originals usually last around 4 years "on the shelf" meaning they rarely if ever actually get used. With no more than 1 deep discharge per year, you'll get right near that 4 years. The MightyMax batteries last around 3 years with the same "on the shelf" type usage but they are 1/3rd the price so I'm making money with "on the shelf" usage. 3. In areas more prone to outages that may cause deep discharges (like where I live), the OEM batteries last no more than 2 years when deeply discharged 6+ times per year. Sometimes the OEMs only last 18 months. The MightyMax batteries last 18 months or a bit more like this so they aren't quite as strong as the OEM batteries but they are close enough that at 1/3rd the price it is totally worth it. 4. These batteries can dump serious power. They handle a great discharge rate (C Rate) right on par with OEM batteries, in fact, the MightyMax actually fair a LITTLE better in this aspect, however not enough to write home about, but again, 1/3rd the price.... you seeing the pattern? Tips and Tricks: 1. The internals of the older APC UPS 600 are actually better than the internals of the new 650s IMHO. The difference from being a 650 or a 600? The battery realistically. Use this 9AH battery in an APC UPS 600 and magically you've got a 650. This battery fits perfectly in the 600 which usually uses a 7AH battery. I haven't seen any issue with Power Chute or anything reporting incorrectly and the charge rates seem to be relatively consistent. 2. The Network 40 ACP UPS has a little riser in the bottom (it's part of the molded plastic). If you cut that riser out you can fit one of these ML9-12 batteries and bingo, you have a APC 650! The battery charge rate is SLIGHTLY slower than the 650 from the 4 I measured but the parts look identical and I have seen no adverse effects during a power outage and run time is consistent. 3. If you have a battery that got a few deep discharges and seems to be shot, you can try using a desulfate mode on a small charger to revive the battery. I've done this with a few batteries that seem to have prematurely died before their time and it works in about a quarter of the cases. Since these batteries charge low and slow inside a UPS, sit topped off all the time, and always have a charge, they don't sulfate much, so this doesn't work all the time, but every once in a while you can revive one the ups is complaining about. These revived batteries seem to last another 6 months or so in my testing. OVERALL: Absolutely worth it. Go with MightyMax batteries every time.

I purchased two for my CyberPower 1500 UPS. The old batteries failed after four years - they usually fail in 3 - 5 years. They arrived in new boxes, packaging, and with terminal covers. The batteries are made in Thailand, but MightyMax is in New Jersey and they have a phone number so I think they will honor their warranty - which they increased to 18 months by registering and posting this review. I have no idea how long they will last, but if they go three years I will be happy considering what I paid. If they fail before 18 months I will file a warranty claim.

Terrific Amazon delivery service and careful handling. Superior vendor packaging protecting the integrity of the battery and the individual power connection terminals. Initial voltage checks were excellent. They were installed without issue and are currently functioning perfectly! Excellent value! Best choice at any price

Bought this to replace a battery in a Monster Rockin' Roller 270 speaker that was gifted to me. It had been sitting in a garage to needed a replacement battery. After reading reviews, purchased this one - great price. Gave it a good long charge and it's working great. Really easy to replace the existing battery, hopefully will last quite a while and hold a good charge. So far so good!

Arrived quickly and correct for the monster RR270. Fully charged as well. Seems strong.

I needed this for my DR Brush Mower. Works just fine. Was a little lower than the original but a little shim underneath the battery fixed that and it fit tight in the mounting bracket.

Great replacement at a lower price point. So far it holds a charge well, and compared to the old battery the difference is day and night. At this price, you could go through a couple of these and still be below the cost of some of the more expensive alternatives.

Good fit for an older APC 600. Mine crapped out one day randomly. Maybe 5 years old on the original battery. Direct replacement, and I don't think you even need any tools to install. Maybe a 5 minute job at most.

Muy buena batería, ayudo bastante a revivir mi UPS.

Replaced battery on my old 600W Cyberpower AVR1000LCD with this 6 months ago. Installation was quick and easy. Works like new and been running great since. Saves me $$ buying a new one.

El producto llegó en la fecha prometida y adecuadamente empacado, sin ningún desperfecto, el material es exactamente como se describe en la publicación y funciona excelente. La relación costo-beneficio es totalmente recomendable.

Perfect replacement fit for the APC BX1300G, and absolutely the best price on Amazon. Took me 3mins total to swap the batteries, and just tested it during an outage last night and the capacity was right on the money. Great product.
