is it normal for a cordless drill to emit a burning smell after buying a new battery?
i have a 19 volt craftsman cordless drill which i have had for about 4 years. the original batteries needed replacing so i just bought a new craftsman 19 volt battery for replacement. however, when i used the drill recently after about 15 minutes it started to emit a slight burning smell (no smoke) from the drill. i was not using the drill as often when the original batteries weakened, but when i did there was no smell. could it be that the increased power from the new battery is causing it to burn off dust that could have settled inside the drill or is there a possible problem with the drill itself?
i'm a tradesman and have used many power tools to me your craftsman cordless drill seem to be biting the dust, because of the internal components are not made to last.
i own a dewalt xrp 510 unit watts like this one http://www.dewalt.com.au/powertools/productdetails/catno/dc920ka/

one day at work i was asked to drill some 25 3/8' holes into a concrete slab to take dyna bolts,i was working on a union site where if i used a power cord it needed to be off the ground for safety reasons on hook, i had a hammer drill to do this with a power cord but couldn't be hassled with finding a power point getting stands to keep the lead off the ground and so on.

so i just used the dewalt, while drilling these holes the drill got so hot i had to stop 3 times to let the drill cool down before i could touch it again, no burnt smell and the drill never missed a beat that day or after. (the drill was still working 100%, it was me that couldn't take it being that hot)

i asked a power tool service guy once what's the difference between expensive power tool and the rest, he told me the better power tools have metal parts which can't burn out or melt which gives you the burnt plastic smell, 

to answer your question i'd say the new battery is working the drill harder than it can take, if the battery was faulty i doubt your drill would even work imo.
the clutch might be smelly, but is it slipping or doing anything else untoward. clutches are a regularly reported problem on one-tonne utes, which suggests most are borderline in capacity. if there is a problem with the functioning of the clutch, approach mazda again about replacing it. if there isn't a problem think about replacing the clutch with a heavy-duty one that's more capable of handling your towing needs. Hello,  
  
Put in new batteries and try again.  
  
If new batteries did not solve the problem, the next thing to check would be the battery terminal.  
  
If
 the battery terminal is rusty, the battery power won't contact and the 
calculator won't turn on. So, use a flat small screw drive to scratch 
the battery terminal so that there would be contact.  
  
If the above
 is not the problem, the next to check would be the wire connecting the 
battery terminal to the the calculator's main board. There is a wire 
between the battery terminal and the calculator board. When the battery 
is inserted, the power from the battery goes from the terminal to the 
board through this wire. There is a possibility that this wire is cut 
in-between or is loosing contact. In this case, you need to get a small 
screw driver and carefully disassemble the calculator in order to check 
the wire.  
  
If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.  
  
If non of the above helps, then it means the calculator is dead and needs a replacement.  
  
Regards. i have a bunch of (unfortunately) amazon anker brand aaa and aa rechargeable batteries. i don’t own a charger because i’ve always just used my roommates’ chargers. my current roommate has a charger that works, because she plays instruments and needs it for things like portable amps i think? i will a… the grease that is their may be thick. get your hair dryer out and warm the total parts that rises and falls when you move your lever.  

continue to move the lever while you're heating the parts. you should notice a big change. try to clean off any old grease. after you do this use some good synthetic oil on the moving parts. never stick anything into a toaster that isn't meant to go in there – you’ll be risking a severe electric shock or fire.


make sure you clean out the crumb tray frequently. this will help keep your toaster working properly and prevent fire.


if you notice an odd smell or any sparking, unplug the toaster immediately and contact the retailer and/or manufacturer.


always store the toaster away from the sink or any liquids that could spill on it.


when the toaster is unplugged and cooled down, wipe the toaster down with a soft dry cloth, but never use water or any sort of cleaner inside it.


if it’s cracked or damaged in any way, stop using it and either contact the retailer and/or manufacturer or buy a new one.


always turn off the toaster at the socket when not in use. If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all.  

OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time.  
If the battery drops to an unacceptable charge level then the battery needs to be replaced hi [@tino52](/u/tino52)

however, there might be other factors that don’t show easily - e.g. radio noise like other wifi or bluetooth devices, badly filtered appliances, quality of your power supply, external circuitry, …

i agree with this, it could be any of a number of things. you are c… From Kitchen Aid they only come on a new motor. I am a Kitchen Aid service agent and I remove them from burnt out motors and keep them. Look for a service agent near you and see if they can help you out. I have no idea where you are, I'm in New Zealand. there are so many things that can cause rough idle, can you give more information? did the car recently overheat? is there any fluids leaking on the engine? are you getting any smoke or steam from the exhaust? when checking for steam, remember to wait until the engine has run for awhile as condensation can build up in your exhaust during the night. if you cannot tell if it is smoke or steam, hold a blank sheet of paper behind the tail pipe, if it is oil smoke, then oil dots will show up on the paper.

some things you can do and check;
check the spark plug wires, make sure they are tightly connected and not chaffed, broken or burnt.
check your pcv valve for excessive oil or clogging, (it will be in a rubber housing or hose leading from your valve cover to your throttle body/carburetor)
i don't know the engine setup in that model, but if you have a distributor cap, check it for cracks and wear, also check the rotary cap.
check all rubber vacuum hoses on the engine for cracking.
if you can afford it, change the spark plugs, plug wires, rotor and rotary cap, these parts all need to be changed over time and your car is getting older now. mercury cell is a type of primary battery. in primary batteries, the charging reaction occurs only once and after it has been used over a period of time, the battery becomes dead and cannot be reused. mercury cell is more advantageous than dry cell because dry cell has a very short life span due to the conversion of zinc to zinc chloride that makes the zinc casing porous. due to this porous casing, the substance inside the cell leaks out and corrodes the metal, reducing the lifetime of the cell. while, in the case of mercury cell, the overall reaction does not involve formation of any ion in the solution whose concentration can change during its life time.
