Q:If one should have a failure with the Ridgid 18 Volt Battery, do you receive a new 18 volt battery or a refurbished one? The reason I ask is my Ryobi 18 Volt battery failed under their warranty and they sent me a beat up replacement that would not work.

            A:  No, same charger for both.

            by|Jan 10, 2023

              A:  My charger came with a tool/battery package; the included batteries were 2ah. It charges my 4ah batteries just fine, so yours should too.

                A:  yes

                by|Jan 9, 2023

                  A:  The charger that comes with a Ridgid 2ah battery will charge a 4ah battery with no problems.

                  by|Jan 11, 2023

                    A:  Hello, Nick - Thank you for your question. If the charger is 18v then it can be used to charge all RIDGID 18v Li-Ion batteries. I hope this helps!

                          Ridgid has failed us
                          The older style of this battery was make with a tougher plastic/resin material, they were coated in rubber, and had battery ejection arms inside. The old batteries would hold the tool in place cause of the rubber molding but since this is 100% plastic they slide all around. Also the older batteries had arms that pushed the batteries off the tool when you squeezed it, no more with these new ones. All for the same price. Less features, same price, more profit for Ridgid.

                              Have had retaining clips break in a year. Poor design, with the hollow circle leaves not enough plastic to hold up. Cost of new batteries is driving me to a different brand. Saws a great saw. To bad they get you on poor battery design.

                                This is a slim lithium ion battery at 2 amp hours that powers all Rigid 18V tools and interchangeable with all 18V Rigid slide pack batteries. And with all slim slide pack batteries I get the power I need without the weight and bulk of the older batteries. This battery worked perfectly after being fully charged and powered my tool. What I like the most about Rigid is that their batteries are forward and backwards compatible. This battery seems like it lasted longer than my older Rigid battery - maybe because it was cleaner - LOL.

                                My husband and I do a lot of home improvement projects so we always have a need for quality, durable tools and accessories. We got the matching drill which doesn’t come with a battery but got this one to go along with it. We have used the 18 volt lithium ion battery a handful of times around the house and haven’t had to recharge it yet. My husband gives it two thumbs up

                                RIDGID 18V 2.0ah battery is a great addition to your RIDGID tools line up or can make a great starter if you are new to RIDGID line up. I have many RIDGID tools and swapping and recharging batteries can get frustrating when you are in the middle of a project. The circular saw, router, sander, folding panel light, these use battery power aggressively and you may run out of juice in 30 minutes to an hour with these tools. I find it handy to have a second or third battery ready to go. I tested this 2.0ah battery with a brushless hammer drill and a circular saw and it provided enough power in both cases. It lasts a little less than 3.0ah battery and a little more than 1.5ah which often comes with drills. You can use this on all ridgid tools with no power problems. With the circular saw it can last 20-30 minutes also depending on the cuts, but with the drill it would last for days. It has a battery level indicator on it and it can tell how much left with the push of a button. I also like how it doesn't drain when not in use, so you can pick it up 6 months later and it is still ready to go. The battery comes with a 3 year warranty, and is backed by the quality and great customer service of ridgid.

                                A replacement battery for all Ridgid 18V Li-Ion Tools, this battery has some minor differences from the original which it replaces. It is slightly smaller and slightly lighter (1.6 oz.) than the original battery. Part of the weight saving, unfortunately, is the deletion of the rubberlike pad on the bottom of the battery case (convenient when placing the tool on a finished surface to prevent marring). It is compatible with all the Ridgid 18V Li-Ion tools and does not appear to sacrifice any performance (when used in a drill and impact driver). It does have a limited 3-year warranty should it prove defective and has internal protection against overcharging, overheating and/or overloading. Other than the deletion of the rubber pad (which also provided some degree of physical protection to the battery) this battery seems to be as good or better than the one it replaces.

                                I am very happy with the Ridgid 18 volt 2.0 AH Lithium-Ion battery. It is long lasting and gives great power while in use. I used this battery with my Ridgid Drill Driver while finishing my basement. This particular battery carries a three year warranty since it was purchased individually, not with a tool. Tired of guessing how much power is left in your battery? That no longer is a worry with the fuel gauge feature on the battery. This battery does not come with a charger, so that needs to be purchased separately. Another nice feature is the Triple Protection Electronics, which protects the battery from overcharging, overheating and overloading.
