Replacement guides and repair information for cordless drills and drivers. Cordless drills and drivers use rechargeable batteries, providing similar features to an AC mains-powered drill without the bothersome cord.

How do I open them and cell replacement

These two old Makita 1434 drill batteries have surpassed the end of their life. I was trying to get a look inside so I could replace the cells but the case has no screws, look at the pictures. There aren't any under the label either.

Their Ni-MH, so can I replace them with Li-on? As long as their the same type of cell (possibly C) it should work?

Thank you.

Just a thought, after you get case apart(sonic welded/glued) take lots of pic's to aid in proper reassembly of contacts/wires/etc.

I know I can get them new, but it's cheaper to replace the cells and get more capacity.

Congratulations Mayer!!

That's quite an accomplishment and other than @oldturkey03 , it's (500K) pretty much out of reach for a long time to come.

@pccheese sure you can do that. here is a pretty good example on how to. Make a guide for iFixit so I have something to go by when I repair my battery
