Biswaye2 Pack 18V 6.0Ah Lithium Ion Battery Replacement for RIDGID 18V Drill Battery R840087 R840083 R840086 R840085 R840084 AC840087P AC840086 AC840085

We use this in our community woodshop. We have 8 batterie impact guns and 2 drills. Rigid brand. These batteries work just as well as the ones that came with the drills. We been using them now for 3 months and have never had a problem. They fit the Rigid charger perfectly. I would recommend them

I needed a couple batteries for my R86007 drill and R86030 driver. The Ridgid batteries were a little pricey at the time and so I bought these. These batteries fit my old 18V tools perfectly and I had no problems charging them and they are holding up. But it has been only a month so I may change my review in the future. I purchased new tools recently and the batteries are not a good fit for these brushless tools which include Drill, driver, reciprocating saw, circular saw, multitool, and router. To be fair, the old Ridgid batteries do not make for a good fit either so it isn't a sizing error on the company but Ridgid just changing things slightly, probably to keep everyone from switching to 3rd party vendor batteries. These are warranted for a year and I will have to see how they last and what honor comes from the vendor if it doesn't. Ridgid has a sale on their batteries and I bought 2 for about a hundred and they have a three year warranty and a store close by in case they fail. Most importantly, they fit my new tools (as well as the old ones).

Second Update: After a few months or so with these batteries they’re just OK. Both still work but they don’t touch the Ridgid battery for capacity. They also struggle to slide well on and off of my drill which isn’t a big deal but it goes to show that attention to detail is crucial. I have a 4 AH Ridgid 18v battery that I still have that’s healthy and it outlasts both of these alleged 4 AH batteries from Biswaye. Do they work? Yes. Will they last a while? They can last you maybe a couple days of regular use but that’s it. As an installer that uses my drills for maybe 5 mins of continuous use each day, my Ridgid battery lasts usually 2-3 weeks whereas these usually don’t make it a week with my current usage. They’ve definitely called off in terms of capacity and I’m starting to wonder if they have problems fully charging because my Ridgid charger says they’re fully charged but I only see 3 of 4 lights indicating maybe 75% charged. This might make sense because the cells may have a shorter lifespan and that’s why these batteries are cheaper. I appreciate a deal but I’m buying a Ridgid battery next time because even a used battery would likely perform better than a new one of these. Unless you’re really on a budget just buy the Ridgid batteries. These are really only if you are that strapped for cash and need batteries that fit.UPDATE: I removed 1 star off of my review because while the batteries 100% work with my Ridgid impact drill and hammer drill, the battery life isn't as advertised. I've got an OEM Ridgid 18v 4Ah battery and then two of these Biswaye batteries that I use. The Biswaye definitely work but the battery life seems to have depreciated to the point of being closer to a 2-3Ah battery, not a 4Ah battery. The battery life check shows that after ~10 minutes of continual use my hammer drill Ridgid OEM battery has 4/4 bars of battery left. When I use the Biswaye battery is shows ~2 or 3 bars remaining with the same amount of use. I will definitely keep using them but I'm not as impressed as I initially was with the battery capacity. I think the battery tech used in these third party batteries isn't as high quality as Ridgid's, thus they may not last years at a time like Ridgid's will. But they're still cheaper for a pair of batteries brand new ($30-$40 cheaper) than what Ridgid will offer so I'm not totally unhappy, just realizing that these aren't QUITE as good as advertised.I have a pair of Ridgid drills that i use for satellite installation. I had a Ridgid battery go bad on me just a month into using it (granted, they were refurbished or open box purchases, but still...). I didn't see how a pair of batteries are worth $100 so I gave these a try instead. The value was much more reasonable and they claim to have the same capacity and compatibility as my other battery. So far so good. I've used them for 2 weeks or so and no issues and the battery life seems to be pretty close, if not up, to par with Ridgid's batteries. Did 1 recharge on each and no issues charging with Ridgid's battery charger either. Good buy and if they last then they're a great buy.

It works just as well if not better.

Do not buy these batteries!!! One of mine stopped working with little use in less than 11 months. Good thing there is a warranty—NOT SO MUCH! It is prorated and I am getting 3 dollars back on a $63 investment. Please don’t be cheap like me, buy something else.

So far work great, but very tight fit in all tools. Same size, weight, and run time as original 4.0 Ah batteries, might be some mislabelling here, but so far well worth the $$.

The batteries fit well ave work, but haven't used them enough to know how they last

The batteries seem to charge and run the tool, but because they don’t lock in they come loose while in use
