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!

Was impressed by the quality of these batteries. Hold a charge for big jobs better than some I have used.

Have been using these for a while and they are working ok. Not exceptional life, but good enough for the price so that I can live with it for light duty use. Have total of 3 different batteries and between all 3 can get the life I need for most home projects. These 3 are just about equivalent to 1 of my Milwaukee M18, 5.0 AH batteries in same use cases. More handling - charging and changing in drill - but much cheaper, too.

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.

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

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.

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.

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.
