APC BE425M Battery Backup Replacement Instructions (Installed Upside Down By Mistake)

Do you need to replace the battery in your APC 425VA unit? Follow along as I replace my battery. NOTE: I installed it upside down in this video. Someone noticed, and that's why I had such a hard time. I have since taken back apart and flipped it - worked perfectly!

Hi, sorry to mention this, but your battery is upside down vs. the orientation that I found when I opened my APC 425. That may explain the problem with closing the case.

My replacement battery was $27 including Prime free shipping. Other than the very narrow screw holes it was an easy replacement. For half the cost of a new unit, it was worth it to me. I think it lasted 4+ years. My original battery has the bottom of the battery next to the base, with the terminals at the bottom of the hole. Still it slide out easily for replacement. The toughest part was pulling the terminals off of the dead battery. An easy replacement. It took longer to locate and order the battery than to replace it.

Thanks for the video, you saved me $37. I also don't have a screwdriver that works with this piece of crap and I wasn't interested in buying a new screwdriver just for this. So, I went Office Space on it and had a lot of fun destroying it. Smashed it on a concrete floor until it was in pieces, recycled the battery, cannibalized it for wires and threw the rest away. Again, lots of fun.

This video really gives one a charge . The fast motion is a real live wire . Did you know that the favorite sport in electric companies is circuit training . Thank you for plugging away .

Always helps to put things back together they way you took them apart in reverse order.

I agree APC unit BE425M it is a piece of junk it uses a reduced size battery and you have to have a super long Phillips screwdriver small enough to remove the screws an order a small shortened battery to put in it it's not worth the money! Do not order one of these off Amazon or anyone else

Thanks! I was able to install my new battery in around 3 minutes or less.

Battery connectors should be facing down when installing the battery upside down... Then it should snugly snap back together (may need to add a little pressure) then you can screw the bottom cover back on.

Having the proper long philips head screw driver is a must for this repair.

Replacement batteries are going for $20 or less now, it's definitely worth fixing.

I like that clock that you had behind you during the video. Does it actually work and where did you get it?

Hey John... I have the same model. I removed the little 4.5 AH battery. Opened up a hole in the air vents where the battery was and ran the cables out through the hole.
I purchased a 15 AH lithium battery on Amazon for $49.00 and spliced in another 6 inches of line cord wire to the new and much larger battery. Easy Peazy. The lithium battery is rated at 4000 charge cycles. Since I only power my modem and router off of this and I only need 10 to 15 min to fire up the generator it should never discharge more than 30%. the new battery should last "forever" .

NERMAK 12V 5Ah was the lifepo4 with overcharging Bms is the one I used . Just yank the small round black speaker off with plyers when you’re in there. Never hear it again..

I just bought one and planning on a 2nd one but I think I am going go buy the big brother instead, more expensive but I think worth it when trying to replace the battery, this looks horrible to replace the battery.

[davidlohr]

My unit was unevetful but the battery is upside down and with the leads facing power outlet side the unit went back together uneventful!!!!

[steveharris]

What type of screws are used to keep it closed...star, phillips, flat

[PurpleMrMojo]

the speaker is black and round on the board. just pop it off which will never again make a noise. its so easy. very common fix

[igobythisname]

How do i know if my battery needs to be replaced? I’ve only been using mine for 4 months. It sat in the box for a few years before I started using it. Once a month or so it beeps and I can’t mute it, i have to turn it off, it’s super annoying!!!

[Drumwolf]

I don't know if you were trying to be humorous in the process of removing the battery and auditioning to be in one of those commercials when they try to make the simple things seem impossible? LOL. You acted like lifting a screw driver was like lifting 400 lbs. LOL!!! Once I over looked your poor attempt to make something simple look very difficult, I appreciated the video showing how to replace the battery and save me some money.

It's definitely a poor product in my experience. First, as demonstrated, the unit is difficult to work with for the purpose of battery change out (it is my recollection APC does not recommend consumer-performed maintenance on the product, and I am sure they designed it to be difficult for all but the most insistent customers, hoping their customers would simply by a new APC unit). Second, when working as designed, this APC UPS provides very little real world time to save one's work, then perform a graceful shutdown while on battery power. It no doubt gets worse as the battery ages, but how does one know the relative battery strength without an external testing port or reliable indicator? Changing the battery is worth the pain if one needs and wants only a very light-duty UPS knowing the above. I am cheap and have replaced my battery twice now.

What type of screws are used on FLAT OR PHILLIPS

[TeodoreThomas]

You put in upside down. The wire section need to go down inside
