The basic rule of getting a replacement battery is that it should have the same voltage as the original. An 18V drill cannot run on a 12V battery. It can only run on a 18V battery. The other thing is that the physical packaging of a battery can be different from company to company. A 12V Ryobi battery may not fit into a 12V Makita cordless drill unless the battery has the right physical dimensions. So make sure the replacement battery looks the same as the old one before you order it. Also, if you are looking for a replacement battery of the same voltage rating and by the same company, know that battery technology is changing rapidly. An 18V lithium-ion battery has a different physical packaging than a NiCad 18V battery.
