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.

Update: bought another set of these for another UPS (we have 4 in total). This is 3rd set of batteries for a CP1350AVRLCD which is our oldest unit. These are a tad higher AHr rated. A perfect fit with F2 terminals. This is an older model cyber power unit and it’s a very tight fit so no room for error. These fit exactly. Previous replacements were from cyber power under a 1 yr extended warranty from Amex that that lasted 4 yrs or so. This UPS was originally for my desktop PC, but got a new one for PC and using this one for the modem/router, NAS and a blink sync module. So a fairly light load now should give us 2-3 hrs run time. With power outage the other day, I saw run time was down to about an hour and battery capacity dropped to 3% just before I was able to shut everything down. Out of the box, the batteries are showing 100% capacity and about 1.5 hrs run time. I think that once the unit tracks actual load for a while, the run time estimate will go up. Past experience shows typical battery life 3-5 yrs. But previous decade living in S FL saw a lot more and some longer outages than here in NC. At a cost of half or less than a new unit, replacement batteries are cost effective. Hopefully over time these prove to be as good as the big name brands. Previous order of these replacements are still looking good. Orig: This is second set of replacement batteries for my cyberpower cst135xlu UPS. Orig purchased 2017, orig batteries lasted 4+ yrs. Bought a different brand of batteries in ‘22 that lasted until recently when PC run time was down to zero during an outage. Self test showed batteries were at fault. So decided on these batteries based on overall good reviews. Hopefully these last longer than the 3+ yrs I got from previous brand. Out of the box they appear to be fully charged, UPS shows 100% capacity and a self test passed - a good start!

Used this to replace the battery in an 800 VA Amazon Basics model ABST800 UPS /surge protector. The batteries in these things wear out but you can replace them in 5 minutes. (Now to find out where to recycle the used battery)

Works as described, its a replace to another battery (7ah) purchased by this company. I wanted something with more power. My last one started not holding a charge this summer after a little over a year of use. It did survive during technically two* Texas summers and a winter. I do like this company and have several of their batteries.

This is my second Mighty Max SLA battery that I've purchased in the last year. The first is in my Honda Valkyrie, and it has been solid and reliable, even though that motorcycle does not get ridden very often. I rarely put it on a charger as it holds it charge well.

I ordered two of these batteries to replace the originals in my Cyber Power battery backup. I received them overnight through Amazon Prime. They were a perfect fit and easy to install. So far they work fantastic and I highly recommend instead of the manufacturer's higher price batteries.

Es tal y como lo pedí lo utilicé para mi UPS tripp lite y funciona de maravilla

The battery in my APC Back-UPS ES 550VA (BE550G) UPS died about a month back and was searching for a replacement. I paid around $75 for the UPS back in November 2016, so I got some really good mileage out of the OEM battery. I was looking to replace the battery with an OEM part, but didn't want to spend over $80 on a replacement battery. Like I said before, I paid $75 for the UPS so it didn't make sense to me to spend more on the battery alone. I'm almost better off getting a new UPS if that was the case. I did some research to see if I could find a non-OEM replacement battery and stumbled across this battery by Mighty Max. It was shipped and sold by Amazon, so I figured I'd be safe if anything went wrong and it was nearly half the price of the OEM APC battery. After exhausting all of my options I ordered it, and received it a few days later. The first thing I did was test it with my multimeter. It was showing a voltage of 12.88V which is good for a new battery. I was reading anything over 12.6V for a new 12V lead acid battery is good. There's cause for concern if the voltage is lower. I also tested the OEM APC 12V battery and that was showing somewhere around 10.57V, which effectively means it needs to be replaced. The Mighty Max battery was easy to install after I got the clips off the OEM battery, and so far it seems to be working well. Since I couldn't properly test the battery life, I gave it no stars for that. I'll update this review if I encounter any issues down the road. Since I got nearly 7 years out of the OEM APC battery, I'm hoping to get somewhere between 5-7 years out of this Mighty Max battery. Fingers crossed.

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.
