Are these new or re-furbished batteries?

Are these new or re-furbished batteries?
Asked by: John
These batteries are brand new, and with two of them in the pack, it gives you plenty of runtime with all of your tools.

Can 4.0 batteries charge on the charger that came with 2.0 batteries?

Asked by: Alan
Yes, these batteries will work just fine on your 18v Ridgid charger that came with the 2.0 batteries.

The add says $99 for the "Pack" yet it also says "each"! Which is correct?

Asked by: gt
This price is for the "pack" which includes two batteries, a great price considering how much runtime you get with two of these batteries.

18-Volt Cordless Brushless 4-1/2 in. Angle Grinder (Tool-Only) with Handle and General Purpose Grinding Wheel is rated 4.5 out of 5 by 1458.

As long as there is no load on the grinding wheel it does fine, but as soon as you put a little pressure on the wheel the tool cuts off in about 10 to 15 seconds. I was hoping to use this to cut 3/8" rebar, but it can't cut the rebar without cutting out. I can get it to cut the rebar but I can't put much pressure on the wheel and it take about 10x longer to cut than my 120 volt grinder. Also the RPMs are very slow compared to my 120 volt grinder. The ergonomics and easy to change direction of the blade cover make this a really nice grinder, if it would stay on. Overall this product is a big dud. I really thought this tool was going to be a problem solver, but instead it is just a problem. Check out the YouTube reviews and you will see lot of other people having the same problem. I wished I would have researched this product.

A bit disappointed that they were not approved for a lifetime replacement guarantee ( perhaps since they were sold as a special price). Other batteries in a tool set did register for the Life time program.

I have a ton of the 18v tools and batteries and had great luck with them in the past. In 9/17 I bought 5, 2-packs of the 18v 4.0Ah batteries. As of this writing, two of the ten are still in service. I have gotten replacements for some of them now and one of those has now died. I have Ridgid batteries still in use from 6 years ago. I haven't torn one open to see if they are using cheaper cells now, because I don't want to void the warranty, but that would be my guess. Yes, the warranty is pretty good, but warrantied junk is still junk. I need my tools working. I have had bad luck with recent Ridgid tool purchases too, but this review is just for the batteries. I would suggest investing in a tool line of a different color.

Rated 4 out of 5 by from great all purpose grinder I've owned this grinder for over 1 year now using it for a large variety of jobs and projects. This tool has been used to cut almost all material you would use a grinder for tile, block, brick, rebar, metal grinding, and much more. The only issue I have had out of the unit is when cutting stone for a chimney there was a large amount of dust and the switch wouldn't turn off. To disable the unit I had to remove the battery and clean around switch with compressed air and spray with electrical silicone cleaner and have not had an issue since. I would recommend this tool to anyone who owns the Ridgid platform or plans to start a kit. It has replaced my corded grinder in my truck giving roughly 20-30 min run time on a 4.0ah battery depending on material cutting.
