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?
