what size is the back up battery?, I freakin drop mine in the dirt
1641768
I believe it is the standard small battery used in hearing aids. I did not keep mine. I sent mine back as I was totally dissatisfied with mine in too many ways to disgust here (I know it should be discuss but that is how I felt about mine).

The battery is a "Werker" Model number WKA12-7F. It is a 12V 7Ah AFM Sealed Non-Spillable Battery. I hope this answers your question.

Sorry but that is a question to ask the manufacturer. I looked at my battery backup unit and typed that into Amazon and bought it.

I can't find any information on the 871b battery even when I Google the number. What do you use it in? Do you know the voltage or the physical size?

The replacement battery is actually a pair with a jumper, fits the case exactly. What APC backup are you replacing batteries in?

I'm not sure but it is a small battery. I'm guessing it is L 7"x W 5"x D 4" I have had it in my bike all winter and I start it once a month and it starts every time without a trickle charger.

Check the owner's manual for the specific battery size, and then check Amazon :)

I don't know what size battery because I returned it before that became an issue. I wouldn't recommend the product. A carpet sweeper would do a better job.

Says "18 AH" on the side of the battery. I bought 2 last year about this time......by July they were both dead...forever. Your choice and your money. My opinion is they suck.

Hi! If you've read my review, you'd know that I dumped that piece if rubbish into the recycle bin. It didn't last me long enough to even give me the opportunity to change the battery once! The whole thing is a piece of junk and should never be sold to the honest person.

mn21/23 12volt (its about half the size of a triple a battery. not sure if mine is defective or not, but ive gone through sets of batteries and they don't seem to last or work well. the light it gives off was sufficient, but I wouldn't buy again.

The battery is of fairly standard physical size. You can get replacements at any hobby shop. There are user websites you can find that give this type of information. Some users even move the battery to lower the center of gravity of the truck.
