Why does my Makita 6011D cordless drill not work when my charged battery in installed? The battery does work on my Makita saw so I know it is not the battery.

Here is a site with a break down and the parts list Makita 6011D Cordless Drill Parts

a bit of heat usually works.

If the battery fits in the tool normally, without forcing it, yes both batteries will work in your tool. The AH (Ampere Hours) rating on batteries is a measurement of how long the battery will last on a full charge. Higher AH ratings means the battery lasts longer on a charge but usually at the expense of a slightly larger and heavier battery.

This happens regular with Makita battery powered tools Try putting the battery in the frezer overnight this remedy worked for me once with a Hitachi battery if not you would be cheeper buying a new drill rather than a new battery.

Unscrew the cover then remove the triger sw then replace it.
