batteries not working?

[MaiTaiMary]

My sister and I each have a month or so old V4L battery that lights up but doesn't appear to work with
any cartos. The cartos work fine on our other batteries. Is this the type of problem that cleaning can fix? And how exactly do I go about doing this? Thanks...and Merry Christmas.

I try to clean mine regularly because they do work much better. I take a q-tip and dip it into rubbing alcohol and clean the metal rings and inside the hole [ make sure it's not dripping wet, just moist ] I also will take a pin or toothpick and clean out the tiny holes on the sides. Wipe with a soft cloth or paper towel till clean. Hope this solves your problem.

Worst case, I've taken and soaked them in a shot glass 1/4 full of rubbing alcohol to clean them out.
It's not highly recommended by many, but I've had success with it.

I also soak mine once in a while but use enough alcohal to cover just the threads!
It sounds more like a post problem to me. Take a pin and insert it just a tiny bit into the hole at the top of the batt. Lift gently while going in a circle (to lift the post back up a touch). That should make better contact and solve your problem.
No idea why it slips down but it does happen.
Good Luck!

I've had poor contact because of juice building up around the post but cleaned them and they worked fine. I just used a toothpick to clean out the build up and then wiped it with the corner of a paper towel.
