Makita BL1850B 18V LXT® Lithium-Ion 5.0Ah Battery

Unless you file, cut, or grind off the wee little tab on the tool receiver plate that keeps the battery from sliding on, these batteries will not fit older tools with the black battery receiver plate without the star. In less than 10 minutes, I cut it off by hand with a jigsaw blade on five of my tools. The BL1830 battery was used in these earlier tools. The older tools only had two contacts, not three, like the newer tools with the yellow receiver plate with or without the star, or the black receiver plate with the star. The extra contact allows the battery and tool to communicate, allowing the battery to shut off if the tool is overloaded or drained past a predetermined level. Overloading a tool causes heat, which is bad for the tool and battery life. br>The ideal situation is to use and store the batteries at room temperature, as leaving them in your truck with the windows up on a 100 degree day with the windshield facing the sun is not good for them. The batteries are harmed by heat. A cooler bag with an ice pack would be useful if you had to lock them up in this situation. Cold temperatures, on the other hand, reduce battery capacity, and using the battery when the temperature is below 0 degrees F is also bad for battery life. Because these batteries have no memory effect, topping them up while using them and before storing them is a good idea. Storing them in a discharged state is bad for battery life, and running the battery until it dies is also bad. If you're going on a long vacation, make sure your batteries are charged at least once every three months, or you'll risk damaging them. Do not leave the batteries on the charger for an extended period of time. After they've been charged, remove them as soon as possible. You must get the job done in the real world, but if you can follow these rules, your batteries will last longer. Some of my BL 1830 batteries have lasted up to 5 years, but others haven't, and did I always follow my own advice? No way! br>So you might be wondering why some of the tools have a small tab on the tool battery receiver plate. It was designed to prevent users from using the small BL1815 batteries on high-drain tools. It's possible that the discharge rate is too fast for the small batteries. I had to coax all of this information out of the Makita techs because they will never recommend cutting off the tab on your tool for any number of reasons, but they also had no information as to why it would be a bad idea, which is their way of saying go ahead and do it but don't tell us about it. In any case, all of my tools are no longer covered by the manufacturer's warranty. I've seen a few reports of people cutting the tab on their tools and having no issues using the BL1850 battery. Keep in mind that the two electrical connector tools do not communicate with the battery in the same way that the tools with three connectors do, so you'll need to be a little more careful about how you use them if you want to get the most out of your battery: don't completely drain the battery and don't push the tool, especially if the battery is low. Some people claim that this battery makes their drills spin faster or that their reciprocating saws have more power than the BL1830 battery, but I believe that this is due to the fact that as the battery ages and approaches the end of its life, it can no longer provide the same amperage (drain rate) or amp hours (capacity) as when it was new. If you compare the performance of this battery to a new BL1830 in a drill, you should see the same rpm and, of course, a longer run time; you'll also see reviews claiming the batteries last twice as long or three times as long, but I believe these people are comparing used batteries to new batteries. Because my older batteries do not have the same capacity as when they were new, I am charging them more frequently. If you are comparing new batteries, Makita recommends getting 65% more run time. The battery warranty has been extended to three years, so I'm guessing Makita believes the communication feature will improve battery life, which could be one of the reasons they don't want you to use it with tools that don't have the third connector. You'll spend less time at the charger as a result of this.

I had no idea what to expect, so I stated that the packaging was used but still sealed on what appeared to be two new BL1850B 18V XLT Li-Ion batteries. on 5. Even if you have 0 batteries, you can use the led battery level indicator. There was no way to charge either of the batteries. The charger's lights alternate between red and green, indicating a problem with the batteries. When I inquired about a replacement product, the seller informed me that there were none available. And what am I hoping to accomplish? Makita was contacted, and I was given the option of sending it to the factory service center or taking it to my local service center. br>br>Recent changes: br>br> br>I found a local service center that could bill them on my behalf. On these specific batteries, it was discovered that an off-brand charger was the source of the problem. It was charged with the original 2. 0 worked perfectly, so I purchased a new Makita charger, and the problem was resolved. I went from a 1 to a 5 star rating. Great price, high-quality product, and trustworthy service. br>I feel bad for giving them a bad review when the problem was not with them or their product.

These are incompatible with my four-year-old grinder, which came as part of a $450 Makita 18V tool package. The rest of the equipment is functional. Another poster claims that the tool can be modified to use the battery; But I can't afford to use my grinder to destroy my batteries. I'm not paid to use these. I'm furious with Makita for not clearly stating that these batteries DO NOT FIT ALL MAKITA 18V LXT TOOLS.

When it comes to numbers, a 5 amp battery blows 3 amp batteries out of the water. They ought to, too. A while back, I bought a cheap knockoff 5 amp battery on Amazon. My guess is that the toolmakers put these out to see what would happen if they didn't. My cheap- o Didn't last a year due to a board overload device melting down during a quick drain saws- everything is in order These don't have that issue; I've drained them quickly on several occasions, but they keep coming back for more. Good buy. br>Take note of the compatibility notes. I have a lot of Makita 18V gear that I've been collecting since about 2013 to replace B's. D stuff. The only version that it isn't compatible with is version 4-. Angle grinder of 1/2" diameter It's a shame, because that device is practically useless for anything serious because the 3 amp batteries are depleted so quickly. br>I know you can change things to make them work, but I'm sticking to the originals. I'll see what I can do.

These factory batteries have a tremendous amount of power. They were able to use my Makita handsaw, which is excellent.
