## Questions & Answers

**Q: has this lasted anyone more than 2 years?**
A: I installed Max Life Battery - ML7-12 - 12V 7.2AH GS Portalac PX12072 Replacement Battery - ML7-12ALT26 (discontinued) and it only lasted a year before the alarm started sounding again.

**Q: The verizon ONT uses F2 terminals (.250 x .3 x .032) measured.  You offer this as a verzion replacment, but say terminals are F1.  Which is correct?**
A: It is true that the terminals on this battery are F1 and the Verizon connectors are F2. Thus, you need to also buy a pair of F1 to F2 adapters (NOT F2 to F1). Big difference. I learned the hard way.

**Q: why does Verizon fios need this battery?**
A: If you lose fios your phone will not work, need the battery backup. This doesn't seem do bad, we have cell phones now but if cell phones don't work (like after 9/11) then the fios phone won't either.   I also need this as battery backup to my hard-wired alarm system.

**Q: Is 12072 the same as 12072HG?**
A: Sorry I don't know..I was just needing a battery for a house alarm but I ended up not needing it.  Good luck

### ⭐⭐⭐⭐⭐ Works great
*by G***. on February 3, 2026*

Working great as my Fios battery backup.

### ⭐⭐⭐⭐⭐ Updated review - great customer service
*by A***R on November 29, 2025*

Purchased 3/5/25 and battery no longer holds a charge. Great price but wouldn't recommend. Not worth contacting company as the warranty requires you to jump through hoops to get approval and return the battery. Decided to buy a battery from a known manufacturer/distributor. This is a correction to the review I posted in November 2025. I finally decided to reach out to the company in January 2026. I am very impressed with customer service the promptness in which the handled the issue. They requested I send some manufacturing date information and within 1 day told me a replacement was being shipped. I definitely will continue to purchase from them. Their customer service is A+!
