Now, plug the charger into an electrical outlet, but only charge the battery for five or six seconds. Type keyword s to search. Today's Top Stories.
Top Stories from Years of 'Popular Mechanics'. Every Single Aircraft Carrier in the World. What you said about Lithium and the complexities, it makes me think that perhaps Samsung need to rethink about their Note 7 and why they cannot get it right.
You might have some ideas for them to consider. Previous post. Next post. Skip to content Your cordless drill can deliver good performance for many years if you use it and treat it with care. Never buy another replacement battery. Learn how to bring back any battery back to life and and make it work like new again.
In order to do this: Charge the drill fully. Discharge it completely under zero load, i. People usually accomplish this by taping the trigger in an ON position.
Charge the battery fully again. Reconditioning requires the battery to be completely discharged to a voltage of 1V per cell. This kind of discharge is the most easily performed by following the deep discharge method described above for removing memory effect.
Battery reconditioning devices are available in the market for reasonable prices. If you can find one, a reconditioning charger is a good investment if you use cordless drills and other battery powered tools. Check your user manual. The charger that came with your drill may already have the reconditioning function in it. Caution: Do not perform manual deep discharges too often. It also causes stress to a healthy battery.
A completely drained lithium-ion battery cannot be recharged by the charger. Sign in Sign up. We've sent you an email with a link to update your password. No account yet? Create an Account Login. Menu Categories. Enegitech Power Tools. Power Tool Accesories.

Using another battery: For example, your 18V impact driver with a Makita 18V lithium-ion battery has stopped working. With the help of an AC adapter for example an old phone charger : You can fix a dead lithium-ion battery up in few minutes. I replaced the internal batteries with ones that were a higher quality and longer lasting!
Others have suggested zapping NiCad batteries with high current It's also only a short term solution. This is a safer method with a guaranteed outcome, and a great upgrade. If you're on a very tight budget and have shorted NiCd cells, you can isolate the bad cells with a multimeter and just replace the bad individual cells.
SUPPLIES REQUIRED: 1 Soldering equipment 2 Small heat shrink tubing optional, if your battery pack requires splicing 3 Large heat shrink tubing optional, if your battery pack has a temp sensor 4 Correct screwdriver bits for disassembling the battery case 5 New replacement batteries see step 2 for help In theory this can be done to just about any item that uses rechargeable batteries, but results may vary depending on many factors.
Do not attempt this unless you are confident soldering and working with high power electrical circuitry - many of these batteries pack a mean punch, especially when assembled! NOTE: they carry enough current to weld in some cases. In this example I will be using the battery from a Craftsman Professional 9. NOTE: This was the first time I've used a very old camera and I did not realize that the pictures were not great until after the project was over Whether or not your battery can be used for this depends on two things: 1 How easy your battery pack is to open up 2 How ambitious you are in opening up your battery pack I have seen three basic types of battery cases so far: BASIC SCREWS: The easiest are assembled with standard screws A cheap security bit set at Ace Hardware contained the bits I needed.
I suggest that you do not attempt to open one of these up unless you could see a way to get it apart cleanly, were desperate to upgrade, or about to throw it in the trash You may be able to re-assemble without any signs that you've taken it apart, or you may damage the case beyond repair There are a few things you need to know about the battery: 1 Size 2 Capacity 3 Type 4 Voltage I was lucky to have Panasonic batteries that were labeled with an item.
Using that item I was able to find all the details about the battery. You may not be so lucky! If you get stuck, see below for how you can find out your information.
If you have any doubts just use a battery with the same specs, however, you don't have to replace the battery with an identical replacement and you can easily upgrade in many cases. If you can't find the details, you can measure the battery and determine the size by searching online based on measurements.
I could have taken out the spacer and used a full size, but I was not desperate for more capacity and I liked the idea of saving money! Capacity: If you are unsure, get the same. However, you can easily upgrade here! This is a measurement of how much energy the battery can store not how fast the energy is released In my case, a mah battery would last twice as long as the mah battery. The more mah, the more money you will spend. Because I was fairly happy with the performance and I didn't want to spend a lot of money, I went with a nice compromise - a mild upgrade of mah.
However, if I was willing to spend more, I could have purchased batteries with more than three times the original capacity! If you don't know your current capacity, there are ways to calculate it based on the output of your charger and the amount of time your batteries take to charge My batteries were NiCad, which have an undesirable property of having something called 'memory' Otherwise, they are a very good battery for use in Power Tools because they can charge fast and are powerful.
NiCad batteries can't handle nearly the same capacity as NiMh, but they don't last as long. In short, I felt that NiMh was a good choice for my application You should consider your situation and determine if switching battery types is an upgrade for you.
If in doubt, replace your batteries with the same type. In effect what I've done is made the drill 'weaker' in exchange for longer battery life. I overlooked that I do occasionally use this for a heavy-duty job. I still get by, but the battery needs to be fully charged or it really struggles to finish the job.
In conclusion, if I really was using this only for smaller jobs the NiMh would be great, but being able to power through heavier jobs is something that I realize now I took for granted. It's like an economy car with a weak engine
