I accidentally plugged a Makita battery charger in while the Makita Lithiom Ion battery was already on the charger. Did I hurt either one?

I don't think any harm was done I have done the same thing and not seen any change in the life of my battery. Also the charger takes a bit of time to fire up as you hear it winding up to full speed and I have just pull one off and stick another on nothing much has changed for me so far. Hope this helps guys.

Lordy no. I plug in the charger with battery in , out , half in. Pull them out early. Short charge etc. overload and over discharge, it handles it fine. My battery life is shorter than some but it's a tool.

I heard from a Makita Tech that this is not recommended, especially unplugging it while the battery is charging. He said it will shorten the life of the battery. That being said, you didn't cause any major damage. The battery will continue to work fine, probably for quite a while. Just don't make your method of choice for charging the battery, and try not to unplug the charger unless your battery has been removed first.

I don't believe this is a good idea. You may harm the tools. Not sure if the charger is different

I really don't know but I do know that after getting the charger, it still didn't re-charge my drill. I ended up getting a new drill all together.

When i bought the batteries i also replaced my charger because the charging light wasnt working. i suggest replac the charger asi did. buy enough batteries to switch out, keep fresh ones capped. when not in use pull batteries out of tool leaving it uncapped. completley discharge batteries before recharging them. hope this is helpful.

If they work fine in a drill or impact then maybe it is your saw. If they will not charge at all I have heard stories of other people having trouble with the chips in the battery going bad on Makita brand batteries. I think that is why i've seen people recommend that you fully discharge the battery befor charging it. I'm not an expert, but if that happened I don't know if their is any way to fix it. Check your lights on the charger and see if there's a error light. Maybe get a hold of the manufacturer. Good Luck!

The question seems wrong. The drill has a female receiver as does the charger. The drill could not be harmed by the charger without some strange type of adapter. I think what you want to know is if the battery would be damaged if it was in the charger when the charger was plugged into the wrong outlet. I probably should have started this response with I don't know. For what it is worth I don't think your battery would be damaged. The charger on the other hand makes me have visions of smoke and also brings to mind the smell of melting plastic. In short I think you have ruined your charger. I hope this long winded answer helps.

Without knowing the state of your battery it would be hard to say. Try the recondition button to see if you can get the battery to work, press the large button until recond light is lit. It takes a while to recondition the battery. Modern battery chargers will not charge bad batteries. If you started with a dead battery, then recondition may help. If the battery was okay then you have a bad unit. I would try it on a good battery before sending it back

I charge my 1234 12volt, 2.6AH battery on a Makita DC1414T. I don't know if there is a difference in charger DC1414 and DC1414T, it may that the "T" stands for trickle charge since the book explaines that at trickle charge the battery can be left in the charger for ever...... Are you dthe Hansen from Slate Hill, NY?

No offense, but you are making a common experimental error. It sounds like you are saying your car started because you put this charger on it for an hour. That is an invalid conclusion. You don't really know the charger was the reason the car started. To determine if that was the case, you'd need to charge the battery fully, then leave the lights on for the same period of time as before, then turn them off, immediately try and fail to start the car as you did before, and finally leave the car alone for the same hour you said you put the charger on the car. Then, try to start the car. This would be a true and valid A-B experiment. I'm betting the car would start in this second scenario. Anytime a lead-acid battery is run down to the point where it won't start a car, if you shut off the battery drain and let the battery rest for a while, the battery will usually recover and be able to start the car.

It is not normal for the charger to spark on connecting. I would buy an inexpensive circuit tester and check those outlets. Just saw on TV news where there have been several fires from leaving Ipad, Ipod & cell phone adapters plugged in when not in use. If you can't find anything wrong have the charger checked by a Makita dealer. Call an electrition if you show anything wrong in the electrical test. Another thought, make sure you don't have the battery installed on the charger when you plug it in. Do that after words.

By that I guess you mean ones that this charger was not designed to work with right? Well, that is a little tricky based on what you are trying to charge. If it is a commercial battery for a drill, you can get something similar to this if you just type the drill's name or model. You don't have to worry about typing the specific battery model number or the specific charger model number and you will see a few results for just the charger mixed in with the results. I typed craftsman 19v and found this one. If you are trying to charge something else or another tool or battery by another manufacturer and you don't know exactly what you are doing, you are asking for trouble but I will give you a few tips. 1) Lithium ion batteries are ticking time bombs. They will explode if over charged with too much voltage or current. 2) LiPo will explode if wrong polarity is used. 3) Most of them have protections from the things that make them explode and some even have them per cell. Some of them though rely on the charger to be smart enough not to over charge and have odd terminals so you can't charge it in any other charger. 4) They all operate in series and some, like this one, even charge in series. Thus with a multimeter, find the polarity of the battery you want to charge and the approximate voltage (I.e. if you have a 24 volt battery and it has 4 terminals and per two terminals you find that they are 10 volts each when low on charge then one can assume that you have 2 sets of 12 volt batteries in a series) then just get some alligator clips and clip them to another power source or power adapter of the same voltage and then sawpt them between the series. One time I really needed a device and I forgot the charger and I did this by connecting the alligator clips to my car for 30 mins then I swapped them to the other terminals for 30 mins too and it got me out of trouble. Just be really careful not to overcharge. Hope this helps.

on top of the batteries there is what looks like a flip up handle - if you flip it up you will see the inlet for the plug, you just plug in the charger and align the pins and plug it in. When fully charged do the other battery.. I bought a second charger so I can charge both at once. But I don't think I would invest that much again. I have a broken bike in my garage. Have had to replace the back rim which is not cheap and the new rim broke within a few weeks -- if you can sell it do so - they are not built with strong enough back rim and spokes

I don't trust Makita's battery technology. I had one that failed and then they were awkward about replacing it , do I gave up. I would describe my use of the battery as normal. At the prices they charge, Mskita should be ashamed of themselves.

no do not leave them on the charger it will burn up you fan this is a big problem Makita really messed up wont buy there tools any more going to dewalt

The charge I have for the Li-ion battery is a UC 18YGL and says Li-ion right on the charger. I have chargers for Hitachi Ni-Cd batteries UC 18YK and it won't charge the Lithium battery even though they both work in the tools.
