Biswaye 2 Pack 18V 6.0Ah Lithium Ion Battery Replacement for RIDGID 18V Drill Battery R840087 R840083 R840086 R840085 R840084 AC840087P AC840086 AC840085

I took a shot at these based on their cost, their performance advertised and their quality. I decided to purchase two batteries instead of one Ridgid battery because of Ridgid's current price. So far, I've been running these two batteries from the grinder, the recip sawzall (have three original ones}, my circular saw, impact gun, etc. every day constantly. They lock in place, the power is great and the time they last is impressive. They charge well even from my portable charger (not a brand Ridgid either) plugged into a standard cigarette lighter plug in. So far I've yet to had an issue even I slipped and dropped one onto the concrete floor hard. Eat your heart out Ridgid!

The batteries came packaged very well and they fit perfectly in my existing charger. These batteries last a very long time and perform flawlessly. Like another reviewer mentioned, these batteries don't get as hot as the name brand OEM battery. They charge quickly and run 3-4 times longer than my old 2Ah OEM battery. I highly recommend these batteries as a direct replacement to the name brand model.

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).

Great batteries for the money. I would buy again. I made a mistake thought one of these batteries was bad after little over a month. But not so. Just pick up wrong battery. After writing a nasty review seller contacted me to try and make it right. Nice to see that. Felt it was necessary to correct my error and give proper feedback. Batteries last much longer then orginally one of course takes much longer to recharge. But great price for seem to be very good batteries. Will update if anything changes.

These batteries were the ticket for me. I had my original batteries for years with no problems until I left my drills in the car one night when it got below freezing. Turns out that's not good for them... Couldn't drive a three inch screw after that. These work fine but they are big and heavy. One thing I don't like about them is they have these weird bumps on the bottom that makes it to where when you set your drill down on a flat surface, they don't really sit flat. They want to fall over. No big issue though, those bumps can be removed with a file.

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.

The dual batteries were fully charged when I received them. Placed them into a Ridgid drill they ran great but would not stay locked in placed. Had to hold the battery pack with one hand while I drilled with the other hand. Tried using them in my sawsall and same thing. They would not lock in place and had to keep one hand on the battery and try to use the saw with the other. Ran the power down in both and then placed them in the Ridgid charger. The charger would not charge either one of them. To bad as the price was reasonable but if they don't work it's not worth the reduced price. Went back to the original Ridgid batteries and things worked fine.

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.
