KINGTIANLE [2 Packs] 5.0Ah Replacement Batteries Replacement for Makita 18V Battery Compatible with 18 Volt BL1860 BL1820 1830B 1840B 1850B

This is the second time I have bought these. The first set. I used all day, everyday. But I dropped one and it stopped working. I wore out the second one. It actually still works 4 years later. But it looses the change within 20 minutes. The new ones work all day and I put them on the charger all night. They work in all my 18 volt tools and my 18 volt radio. My truck battery died once and I hooked up one to the truck battery. I let it set for 30 minutes. Came back and my truck fired up. I don't recommend it. There not made to jump start vehicles. But I was in a pinch. Worth every penny. I just wish they had a place to send my old batteries. I hate to just toss them into the trash.

These were initially having troubles charging, but now work fine. Could have been dirt build up in my charger or something. I was concerned there would be trouble and have to be sent back but they are both working great now. Much stronger charge/power to my ryobi tools, especially notable in my blower. It works better and longer!

*New Update at end* Hey Fellow Amazonians! Admit it. You're on the fence but, don't want to waste money on a long shot. Don't worry I took the shot for you! I'm an avid Ryobi fan. I have tons of their tools but, lately they've gotten real proud of their batteries and it shows. Prices are outrageous! I recently bought a Ryobi 1800w inverter/charger and it holds 8 batteries. I wanted to be able to dedicate some batteries to that. So, instead of mortgaging my house, I decided to buy 4 of these. Sizing: These batteries are the same size as the 4AH official Ryobi batteries. I honestly hoped they would perform at least as well. Performance: "Thoroughly surprised" is what I would say. I have the Ryobi 12" hanging fan and one battery will run the fan on 1 for almost 3 days nonstop. They're amazing. When I use them in a heavy amp draw device like the angle grinder or the lawnmower, the batteries show their limitations. They are not as powerful as the branded ones. The lawnmower will bog down easier. Is it a significant difference. Meh. It's noticeable but, not a deal breaker. Look these are AMAZING and INCREDIBLE batteries. They are 100% worth the money and then some. Buy them, abuse them, like them, and be happy knowing you got a good product!! Update a few weeks later: Assumptions: 1. These are just repackaged/recycled Ryobi branded batteries. 2. These are of their own design based solely on amp draw limitations. Well, it's answered. Assumption 2 is correct. These batteries are 100% of their own design while using the Ryobi 4AH as the base. Findings these versus the real: 1. The guage of metal used on the terminals is slightly less. The quality of metal used is also less. Look at the corrosion already building on the middle terminal with the cheap soldering job. 2. The battery management board is completely different. However, I like the thicker traces and less complications on the knockoff board vs the original. 3. The knockoff uses their own branded Akko Power 3000mAH 15amp cells while the Ryobi uses Samsung 20Q 2000mAH 20amp cells. That would cause the slight amp draw limitations of the knockoff versus the original. What are my thoughts and are they still the same... YES. Besides the comparitively basic board of the AKKO Power, the actual build quality is very good. Time was taken to well insulate the cells and Id have to admit better than the Ryobi. Knowing these things, I will continue to buy these Akko Power batteries as they are cheaply priced with very reasonable build quality!

Junk! Weight a little more than a 2 Amp Ryobi, not as much as a 4 amp. Last a little longer than a 2 Amp Ryobi, but not as long as a 4 amp. These things are supposed to be 6 amp. Yes they were cheap And yes they are cheap, AKA Junkie

Why did you pick this product vs others?: I’ve bought 2 of these packs so far and will likely buy more. Life is good, power output is good. The locking latches are a little stiff and hard to take out of tools and chargers if you have smaller hands. Overall amazing value.

I like these batteries. My name brand batteries do my drills did not last very long. This is the second set of this brand of battery I have purchased and they have been working great. The last set I bought is over a year old. I checked them with my multimeter, and they are a little over 18volt (around 20) which is nice for things that you want a little more speed (like the leaf blower).

These were heavy and didn't last as long as the time shows. Charging was fast.

Excellent, so far working in Ryobi original charger and fit the device while performing well. Batteries are heavier by about 2x(message to the ladies) but do last a little longer then minimum battery for sure. Lets hope that life cycle of each battery will be as long as original. So far the batteries are great resourcing power when you need it to pump your tire with Ryobi Air Compressor or screw that nut. Worth the price due that battery will last longer and if you are in crucial situation and trying to get as much power from every charge of the battery - you will have no issues. Tested for 3 weeks and recommend it.

Excelente precio y totalmente compatible con las 9 herramientas que tengo del sistema Ryobi One. Almacena ligeramente más carga que una batería Ryobi de 4Ah.

These batteries perform as well as the original Ryobi batteries. They charge like Ryobi batteries They work in Ryobi tools just like original batteries

Works great, should have bought them earlier, good amp capacity. Well recommended

Absolute junk. Do NOT order. These are impossible to take out of your tools/charger. One battery stopped charging 3 months in. Save yourself the headache and just set your $70 on fire.

The locking clips are not as easy to use as original Ryobi batteries, and the units are difficult to remove from tools as they seem to fit tighter.
