batteries not lasting


Recommended Posts

The triple hammer is pretty damn nice. 

 

I still love my DTD154. With a BL1820B it’s the perfect size and weight for my belt. 

I ran a hundred feet of EMT with 3 self tappers per 10feet. A couple holes in steel and some KOs cut and my battery was at 75%.

Yeah I had the td170dz and only one battery and was able to keep it going without the battery dying. Loved that impact. Perfect size and power.

Hey guys, 

I run makita everything and am a commercial glazier. I'll spend all day constantly drilling into concrete either m8/10 with my drz202 hammer drill, cutting down bolts on my grinder and fastening with my impact. 

 

I bought 2x 5ah last year and have already had them replaced by makita, they would say fully charged but once they showed 2 or sometimes even 3 bars my hammer drill would die. 

On the hammer drill it would show the battery only has 1 bar but on the battery it would show 2 or 3.

 

I have just taken my 6ah batteries back that are less than a year old because they are doing the same. 

 

Its winter here and In the cold wind it will take up to 1.5hrs to charge, out of the wind the normal 45mins.

(yes this is a thing, mind you has to be super cold as in the battery itself isn't even slightly warm while charging) 

 

Today I've bit the bullet and bought the new makita BL DHR242 with vacuum attachment which is supposed to give us 30% more battery life than the brushed. Fingers crossed this helps. 

 

At the moment I'm going thru batteries like crazy, I'll get maybe 10 holes drilled and 10 bolts installed before the battery dies (brand new battery) on both my 5ah and 6ah.

 

Im guessing the cold in general is not helping (im wearing 7 layers and have heated insoles in my shoes!) 

 

Anyway, i hope that gives you some idea on battery life. 

 

Makita batteries all come with a 3yr warranty so don't be afraid to take them back when they play up! 

 

Cheers guys

If it's just happening on that one tool, my guess is that something is wrong with the tool.  It seems weird that the batteries die quickly and even the new ones.  With all the electronics in tools these days, maybe something is wrong with a circuit board in the tool.  I am sure cold can effect the batteries as Lithium doesn't like extreme cold.  However I still think it's weird that multiple batteries are having problems with the same tool.

Hey mate, nuh it's the batteries, all my tools are new, the batteries did it with the older tools and now the same with the new ones. 

I get roughly 20 holes in concrete with an 8mm drill bit going in all the way. 

 

Its just old technology, makita use VERY VERY old lithium tech. 

 

I don't mind, I'll keep taking them back every year for new ones until they're sick off me. 

 

Hammer drills are pigs on batteries, but makita are the worst. 

 

Compare it to my battery caulking gun - i can use a 3amp battery all day long for a week or two before it needs a charge. 

 

Completely different power being used 👍🏻

I have had a Makita reciprocating saw Model BJR182; I bought it many years ago.  It was the first Makita tool I bought.  I now find that none of the batteries that came with my subsequent Makita tools will even `dock' with the base of the reciprocating saw.  I notice on the saw it says to only use a BL1830 battery.  All my other batteries are BL1850B.  All tools are 18volt LXT units so one would think they should all work together.  I have not had a reciprocation saw to work now for many years and the saw only serves to be a ugly paper weight.  I was reading in one of the forum texts that some one was saying the only reason the #3 units are around because there are older tools that only run on them.  He went on to say that they can be converted by installing an adaptor part.  What is the story; are these #3 batteries still available or can I buy parts to convert?

See this thread:

 

 

If I were you, I would file off the nub since your saw is already old, out of warranty, and a paper weight - in other words, you have nothing to lose. I think the worst that could happen is you burn out the motor or electronics... just don't run it for extended periods.
