Hello Mike, Thanks for your question on the RIDGID 18-Volt 4.0 Ah Lithium-Ion Battery AC840087. The batteries are interchangeable in the tools. However if the charger is Nickel Cadmium only it will not charge the Lithium Ion batteries. I hope this helps! - Eve

Great question Andy! You can use the RIDGID 18-Volt 2.0 Ah Lithium-Ion Battery AC840086, however the OCTANE tool + OCTANE battery communicate for maximum performance in high demand applications and are designed to deliver maximum power to OCTANE tools along with extreme runtime. Thanks for asking! - Eve

Answers

I believe all of the 18 volt are compatible with rigid. My original 18v combo kit that is 12yrs old works with all Rigid 18v batteries from the original nicad to the newest Li ion batteries.

Why is this $299 and the 5 tool combo kit $289? Don't make a lot of sense to buy this

good small radio but need improvement.
First of the all, the whole package did not come as retail package. it is fine by me because i did not have to rip anything open. lol. the radio is light weight and easy to carry around. sound was mediocre. i think my cheap milwaukee radio (2590-20) sounds better. but for a single speaker, it does pretty good job. sound is still clear even at loudest volume. it comes with a short 3.5mm male/male cable to connect aux port. honestly, the cable is too short. for a radio that does not have compartment to store a phone, that cable is useless. the bluetooth connection is good. i played my music from youtube no problem. i did try the ridgid radio app briefly. it functions well. it gives me control of the radio while on bluetooth. it did crash once when i tried the announcement function in the app. but that function is useless. tried a few times and it doesnt work. i agreed with other review about the app. why does it need my location while connecting it? it doesnt make sense to me. charging port is slow. it can keep up with the music playing and bluetooth function but it is not fast enough. overall it is a good jobsite radio but there are some cons i want to see ridgid will implement for the next radio. - wish it comes with a power cable. - faster charging port. - an adapter or pocket that can attach to the battery for phone storage. - a handle to hang the radio.

Provides enough power to remove lugnuts and rusted bolts paired with a Ridgid impact driver. Definitely a new fan of Ridgid products. Unmatched quality and warranty!

I bought this on april 13, 2020. I go to register the kit and it tells me to enter a correct item number. If you are going to buy this and try to register the kit forget it. Go buy something else that can be registered.

Example, when you buy tools is fine but if you going to have problems with same than you have problems, thay said lifetime service but if you didn't register your tool waranti doesn't work. I bought kit tool for house and didn't use it maybe 15-20 times in 11 years and battery want charge, 2009 i start to register tool but didn't finish for some reason and thay can't do anything about it, I will check how much is 2 new batteries and how much Ridgid company will lose if they send free 2 new ones.

I've been using Rigid cordless tools for 15+years. And I'll continue using them. These batteries give great power and are very long lasting. It takes a lot to overheat them, and when you're working long hours you need your mental, physical and rigid batteries to get you through the day.
