    Does the job, fit well in ups

    Bought this from vendor Mighty Max Battery to replace the old nonfunctional battery for my UPS. This battery physically is identically sized compared to the original battery and is a drop-in replacement for the TrippLite G1010USB UPS. It arrived fully charged and ready to go, registering all 5 bars on the UPS charge meter and over 12 volts on a voltmeter. The battery terminals are appropriately positioned and are the proper size. The battery is labeled 9 Amp Hours. Delivery took a week.

    I have just finished installing this battery as a replacement in my TrippLite G1010USB. Like many people, I have some dead UPS units around. Replacing the whole unit is ~$120. However, the only real problem with the unit is the battery – so the choice was to try rehabbing a UPS for the first time for $22. Installation was easy. The battery arrived perhaps 60% charged (the little bar display on the UPS shows 3 or 5) and is plugged in now charging up to full. Note that this battery has the smaller F1 tabs while this UPS and the old dead OEM battery hve the larger F2 type connectors. This is not an issue, as you are attaching a larger cable connector onto a smaller tab. The connection is firm and tight. I did put 2 small pieces of electrical tape over the connections to prevent any possibility of an accidental short (ie, I dropped the screwdriver). The packaging made me a tad nervous when I first saw the box, as it was slightly crumpled during shipping and the battery is heavy. However, upon opening I found the packaging was better that expected. Crumpled brown (kraft style) paper kept the battery centered in the box. The battery itself has an inner plastic wrapping, and outer bubble wrap. After using a box cutter for the outer box tape, everything else was opened with no tools. Shipping arrival was ahead of schedule.

    Battery fit perfectly and is performing as it should. Very happy with it.

  7. John Hawkins

    Wonderful product and reliable service. It works perfectly with my Tripp-Lite UPS (ECO 550), and it is better than the OEM with higher capacity (9AH instead of 7) at almost half of the price. A very good buy from Mighty Max; highly recommended.

Mighty max brings the battery backup back.
Arrived well packed in unopened sturdy box. Was replacement for identical Mighty Max battery I ordered 2 years ago. Taking 1 star off because didn’t include the needed terminal clips - was able to use the old battery’s clips
Same model fits in each of our four wheelers great product
Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.
Direct replacement for generac portable electric start generator. Works great.
Received really quick. Boxed well and fit great. Worked like a charm! I would definitely recommend this battery.
As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
Needed a replacement battery and the manufacturer wanted $50 whereas you only required $20. Made it worth it!
satisfy with price and easy installation.
Arrived in great condition comes with the bolts to attach the wire over all very satisfied
