Rated 5 out of 5 by from High quality High quality battery, used with my C12MT multi tool, really good for getting into tight spaces, but bear in mind it's only 2.0ah and with the multi tool being on constantly it drains very quickly. If it was being used on something with less intense use, like an impact wrench it would be sufficient for most light jobs.
