Re: Another Makita Battery Bites The Dust!


I think there is another part to this puzzle. I have since tried my second charger, it will not charge the old batteries but the other will. I noticed the serial numbers are quite far apart, maybe it's the older dc18ra chargers that work with them and the new ones are different. at some point I will take them apart and compare the circuits to see if one is a newer version with different parts. Wish I had an LCR meter.

Re: Another Makita Battery Bites The Dust!


Thought I would add this.
Yesterday I'm using my Makita 3amphr 18v lithium ion battery and it runs down.
I put it in the charger, not right away, maybe 1/2 hr later, and I get the light code saying defective battery.
I thought shoot, I just bought this 11/30. I guess I got a beat battery.
I was too busy to mess with it and just left it sitting in the charger,
When I was packing up my tools I realized I forgot to unplug the charger and low and behold the defective battery now showed a green fully charged battery.
I thought the charger was screwed up and put the battery back in my cut off tool and it was in fact all charged up.

Some point in the course of 4hrs the battery accepted a charge??

Interesting. I will try that on the next pack when it goes bad. Perhaps the pack got above cut off voltage and started to charge.

Re: Another Makita Battery Bites The Dust!


@TimNJ- Funny enough I was just reading this review and one of the commenter’s noted the same thing, I don’t think he has used cordless makitas before:

the review: http://bit.ly/1aLUieu

the comment:

I have 18v Li ion makita battries with the DC18RA charger, almost brand new, it almost always goes red/green when i first plug a battery in to be charged, I just leave it in and in 20 minints or so it is green, ready to go. am I missing something?


@BCC- My father in law also has a low serial charger which will charge makita batteries bricked by others. he says he bought his in 2006.



I got a nicd model 18v 6-1/2" saw(5620D), was showing it to my father in law and we got talking about the batteries. He has mostly genuines with a couple "powerextra" generics. My generics are the other type, "POWERTOOL BATTERY". Anyway his two crapped out the other day in the sawzall. Mine have been put under heavy use in a coworkers skil saw and sawzall with no ill effect. both of our batteries are about the same age. It's worth noting that his are the 3ah while mine are the 4.5ah. Perhaps the generic cells can't support that much draw and having another set in parallel is the cure or the powerextra brand has cheaper cells. I did notice that the powerextras have many negative reviews which is why I chose to go with the ones I did.



When his failed to charge it went like this: standard beep and red solid light for 20 seconds and then all 3 lights would go steady for 5 seconds followed by a solid green light indicating a full charge. This tells me that these generics do have protection not allowing burnt out cells to be recharged. I am going to save his packs and get new cells for them.



I will be recieving a nicd model 18v sawzall in a couple days as well, cant wait. I will try the skilsaw tomorrow and report back.

Which light code did it throw? red and green solid or red and green blinking? Solid means 80% charged the other means defective.

Re: Another Makita Battery Bites The Dust!


I thought I would give it a try. No luck for me. 6 hours later, battery still shows bad battery.
Oh well. Not like it cost me anything to try.

So. Invest in more batteries with a very short life span or leave a great drill and impact sitting?
Short life span in my opinion.

do not know how much or how you use your tools .if all you have is a drill and impact then not alot holding you back from looking at an upgrade or a shift to another brand . Are they brushless ? if not then that is something to consider .

Re: Another Makita Battery Bites The Dust!


For the past two days I have been trying out the nicd circular saw with the 4.5ah generics using the liondapter battery adapter. It works great. Thought for sure it would stop a couple times when the wood was pinching and it kept going. I don't know about you guys but the two generics I have more than compensate for the genuine batteries.

If your makita batteries "bite the dust" I suggest trying one of the generics, preferably the 4.5ah. Also the Liondapter is great because you can use your nicd tools if you still have them with the lithiums.

Re: Another Makita Battery Bites The Dust!


All we use are Makita cordless. The 1.5 Ah and 3.0 Ah are sometimes different. What I mean is the cordless sawzall and circular saw do not accept the 1.5ah batteries. WTF. Also some of the chargers that come with the 1.5ah batteries do not charge the 3.0ah batteries. We have about 10 drills and chargers. I was dead set on the DeWalt 20v impact drivers until I found out the nose of the gun only has one ball bearing and a small clip to hold the thing together and when that goes your bit falls out. Ive had some rebuilt 3 times in a year. JUNK. I stick with Makita. I would love a better battery situation, but I am not looking forward to purchasing 2 grand worth of "new" drills and batteries just for the battery. And as for when a charger or battery goes out I just buy a whole new case with drill, 2 batteries and charger. I can't justify paying $100 per battery when I can buy a whole new drill setup for $300. You know the moment you buy a replacement battery then the drill will crap out. Then you got a new battery and a broken drill....

Mine threw the "defective" blinking light when I first put the battery in.
I have the black chargers.

I was thinking of getting the nicd adapters since I have quite a few 18v tools that still work great, but I figure those NiCad batteries are going to start becoming obsolete.

I bought my extra batteries and charger from ebay.
There are guys that apparently buy the kits on sale then sell them out piece by piece for cheaper price than to buy the single pieces from a dealer.

This is how all those flea market guys would sell brand new Craftsman wrenches for close to half what they would cost in the store.
They bought the big sets at the discount then just broke them up to sell pieces.

Just trim the one side of the 1.5 and they will fit in everything.

Re: Another Makita Battery Bites The Dust!


That's a bad idea. Modifying the tool to take a higher amp pack is fine as the tool only pulls the Amps it requires but putting a lower amp battery in a higher amp tool can destroy the pack almost instantly if overloaded.

Going 2 years like that with no problems. I rarely use them in saws since I have plenty of 3.0 a 4.0. But it's nice to have them fit everything

Yeah they will be fine in the lower amp tools. The saws and sawsall will pull major current. Even the larger drills can.

Re: Another Makita Battery Bites The Dust!


Just thought I would update. I bought these: www.ebay.com/itm/111876824228
for $148.75 back in august of 2015, 5 months no issues, even when cutting castiron with the sawzall or 4bys with the skilsaw. I work 5, sometimes 6 days a week so it's not like they don't get used a lot.

On the other hand work bought a bunch of makita kits about 6 months ago and have had issues with 5 packs and a couple tools and 80% of the guys, many of whom have other makita stuff say the 3ah packs don't seem to last like the older makita ones or the other brands. Of course makita moved production of everything to china shortly after the lithium tools came out.

I think the main benefit with these generics is that each cell sees less draw because there is 3 sets instead of 2. I do have 2 1.5ah made in japan makita batteries that were given to me, they stay in my tool pouch but really only see the impact drill or to make a pilot hole, still they are working at like 6/7 years old. Too bad makita has decided quality in the most crucial aspect of cordless tools wasn't important to them. I really like makita too

Also an old wood blade will cut 16ga sheet metal pretty quick and the batteries won't flinch.

Are the batteries you have entirely made in japan or are only the cells made in japan? Current batteries with leds are assembled in china with cells made in japan.

Re: Another Makita Battery Bites The Dust!


With leds? as in light emitting diodes? As far as I know makita doesn't have any batteries with status indicators. There are after market ones with led indicators, mine do not have those. The generics off of ebay are entirely china. The two makita ones are cells from japan and assembled in china, sorry I wasn't specific.

I will have to check the ones at work. At the end of the day it really doesn't matter. I have worked in manufacturing and I know for a fact that the customer(makita) gets what they ask for per their prints. If you say the leads need to be 5"+/-.5" you will always get 4.5" leads on the nose. The only time a product is bad is when the customer doesn't check quality of the parts it buys or if they ask for poorly designed product. Any issues with makita products are because of makitas choices, just like every other company.

Don't get me wrong, there is a lot of cheap chinese krud out there, but that is not on accident, and it isn't the manufacturers fault because they are making a product to specs. If specs are to be as cheap as possible, guess what? China has a bad rap because they are the largest, most well known exporter of goods to america in an age where companies care most about the bottom line. Japan has a good reputation because japanese manufacturing was cheap when american engineers and companies still asked for good product.
