Bought quite a few Makita compatible batteries but they don't last and I killed last two on the Makita fast charger. The genuine Makita 5ah batteries charge from empty to full in 45 mins on the Makita charger. My first battery was a Makita (second hand with a little selection of Makita tools from my Son-in-law 5yrs ago) and is still going strong. I've gone through 6 compatible batts during that time all now deceased. Decided this time to replace with genuine.

Before you buy, watch some YouTubes about counterfeit batteries. I wish I had. My genuine Makita batteries last about 20-25 minutes in my Makita leaf blower. These last about 4-5 minutes. At first, I thought they were defective but after educating myself via YouTube, I now realize these have every indication mentioned regarding counterfeits. Apparently, this issue is rampant, but I would have hoped Walmart had some kind of quality control process in place regarding third party vendors. If the price seems too good to be true, there's probably a reason.

COUNTERFEIT PRODUCT, NOT GENUINE MAKITA

These are counterfeit batteries. Very good fakes, but still fake with no warranty, don't perform as advertised, and flat out lies in their marketing. THIS IS NOT A REAL MAKITA BATTERY. This is a cheap knock off, hence the price. These batteries do not have the overload or short circuit protection that real makita batteries do. They do not perform as well. I will be returning ASAP.

Deceptive seller practice.
12 January 2024

Ordered 6 Makita batteries, 3-2 packs. Thired party seller. Received 3 Vanon replacement batteries. They offered refund for 3. Return is proving impossible, because product received is not what was ordered. Seller wants to sell me the inferior batteries. Walmart not helping so far. Seller may be doing 'bait and switch' or just plain fraud.

Great price if they are a legit Makita product.
18 September 2024

When I ordered the batteries, I thought they were going to arrive in factory sealed packaging. The price was great, but when I seen it arrive in a cardboard box and they were in a plastic wrapper in that, I thought, crap, another counterfeit battery purchase that won't last.I had bought cheaper batteries like this before, that looked exactly like the Makita brand, the writing, serial numbers all the info, just like my originals, but those were counterfeit. So this is what I thought I just bought here. Now presuming I am a bit wiser, I looked up the tell tale signs of a genuine Makita battery. These passed the ID test. So now it is just a matter of time to tell if the counterfeiters have that detail down too.My original, genuine batteries are still going strong, ... MoreWhen I ordered the batteries, I thought they were going to arrive in factory sealed packaging.

The fake ones I bought did last a year.

Low quality batteries with false capacity.
2 December 2023

These batteries are advertised as 6 Mah. I purchased them because the main photo was of a battery with 4 LED charge indicators. Instead, I received batteries with 3 LED charge indicators. I did not want them because the ones I have had are of poor quality and don't hold a charge very well. The genuine 6 Mah batteries I have last about 12-15 minutes in my blower on high speed. These last about 5 minutes. I advise that anyone who wants good batteries shop for those with 4 LED indicators and ask about the batteries you will receive before purchasing. I no longer buy batteries here because there are to many sellers of low-quality products..

Makita BL1850 18v LXT 5.0Ah Li-Ion Battery
17 July 2024

Purchased to go with my split shaft Multi Function Power Head, the battery charges pretty quickly and bar indicator shows the state of charge and amount of power left. I’ve not had it very long, but from my experience using it with a brush cutter tool fitted with a steel blade, the battery seems to last around 30-40 minutes when worked hard on full power. I’m sure this will improve when used with a strimmer head under more normal circumstances, but I’d say its advisable to have a spare battery or two just in case.

Quality Product at a Reasonable Price

Fine battery, and the best price at Tractor Supply. I like TSCo. It is a great version of the hardware store that has a little bit of everything. I didn't know that they carry Makita. I've been at TSCo often and never noticed their Makita products. I found this out by accident while searching the Makita website. It was a bit like traveling around the world to discover what wanted was in your own back yard!This is a bit of a plug. Everyone has a reason to use a certain platform. For me it was Makita or Milwaukee. Milwaukee makes a good product, but the options for the different tools I can use on the Makita platform is what sold me on Makita. I can use this platform for gardening equipment, automotive such as torque wrenches, even fans in the van to keep the dogs ... MoreFine battery, and the best price at Tractor Supply. I like TSCo.

Renewing my Makita collection

Replacing my 12v drill with 18v and 40v items. More power, longer batt life. The 40v driver drill is a beast. Makita's decision to put the fwd/reverse switch where it is was not optimum, your thumb/forefinger keeps changing its position.Also got the tire inflator, reciprocating saw, 18v driver drill.

The battery works
27 August 2024

These things could be anything, it would be impossible for the average person to know what is contained within these sliding plastic constructs that fit a Makita charger. One way to know what you have would be so see how long they last. I already killed one of mine through no fault of the product by trying a trick shown on the internet of hot wiring one battery to another to see if you can reactivate an old battery. That sent one of my two batteries into the trash can. These batteries are a fraction of the cost to the Makita originals, and we all would hope they give us good value, but we don't know.
