If you have one or more of the Ridgid line of 18V cordless tools, this battery will give you extended use without needing to recharge or swap batteries. Rated at 18V, 6 Ah, the Lithium-Ion battery is claimed to be compatible with all the Ridgid 18V tools (I can verify that is true for their ½ inch drill motor, ¼ inch hex drive impact driver, receipt saw and oscillating multi-tool). Compared to the 2 Ah versions of the 18V battery, the 6 Ah battery is, understandably heavier, though at 25.8 oz. the weight tradeoff for more capacity is reasonable. It is 60-80% heavier than the 2 Ah versions, but the balance when using the tools (even the smaller ones, such as the impact driver) is still good, due to the weight being below one’s grip. As on other of the 18V batteries in this line, there is a four (4) bar charge indicator. As received, it showed one (1) bar, and took approximately 2 hours to fully charge it to the four (4) bar indication. The battery is eligible for the Lifetime Service Agreement (LSA), which requires registration of your battery, but will provide for free replacements should it become unusable. This is in addition to the three (3) year warranty against defects. If you find you are frequently having to stop and change or charge batteries, this will save you a lot of time, allowing you to continue to work.

This is the first battery I’ve ever used rated at 6ah. I successfully used it to power the 1/2 in drill/driver. My project was to drywall a basement of about 16 x 20- including ceilings. Even after a few undo’s and redo’s, I still had 2 bars left on the battery. It’s a pretty big battery, but still, that’s a lot of work for a single battery of any capacity. Can’t wait to see what else I can do with this animal. Very pleased and surprised how much this can do. Nice to have a battery that can go the distance without having to be charged at lunch time.
