Cordless Drill Battery Won’t Hold Charge-Overcharging,Resetting and Checking
The thought of knowing that your cordless drill battery can no longer retain any charges when charged can be quite frustrating. As such, some people quickly get rid of their battery and think of how to get another one.
Are you facing the same problem? You don’t need to throw your battery away so soon. There are measures you can take to make the battery useful again. On this post, you will be learning everything you need to know regarding a cordless drill battery that is unable to hold any charges.
Can you overcharge a cordless drill battery?Many people complain about their cordless drill batteries not charging or working after they charge the battery. But after a careful observation, it has been discovered that some of these owners are the ones killing the batteries themselves without them knowing. That brings us to the question above – is it permitted to overcharge a cordless drill battery?
Overcharging any kind of rechargeable battery is only a systematic way to bring the battery to its early grave. Cordless drill batteries fall into the category of rechargeable batteries, so they are not exempted from this general principle.
It is always specified that you disconnect your rechargeable battery from its charging source whenever you are done. Failure to do so will keep weakening the battery, and reducing its lifespan by an incredible percentage. So you should never leave your drill tool’s battery charging when you know you don’t need any charge.
There are a select number of cases where a rechargeable battery is made to charge for longer even after when it has become full just so the battery will gain its energy capacity back. Battery experts call it deep cycle charging. In most cases, this sort of charging will have to be undertaken every once in a while.
Therefore, if it has been specified that your battery should be put through such charging conditions once in a while, then you can conveniently do so. But if you have not seen anything as such in your users’ manual, then do not attempt to do any sort of long charging or leaving the battery connected to the charging source forever.
Simply put, it is unwise to overcharge a cordless drill battery all the time. It is only helping to reduce the power of the charge, and render the battery useless overtime.
How do you reset a cordless drill battery?After confirming that your cordless drill battery is bad or dead, you don’t have to throw it away just like that. Just because it has refused to charge that does not mean it is of no good. You can actually use it again if you know how to reset it.
So if you are asking yourself how this can be done, don’t break a sweat because that is what you are going to be learning on this post.
Why the cordless drill battery is not charging is because it does not have any single charge inside it. It is completely flat. Therefore, if you want to reset the battery, first you need to get a battery that works fine. Get 2 pair of scissors or any conductor that can help you connect the terminals of the two batteries together.
Before we proceed with what to do, I don’t have to tell you that you ought to be extremely careful when doing this. If you do it wrongly, you may not get the results you seek.
Confirm the positive terminals of both batteries, and use the pair of scissors to link the two of them. As I emphasized earlier, you can also use any other form of conductor to link them. Do the same for the negative terminals (both the negative and positive terminals have to be linked simultaneously).
Hold the scissors in place in the form of an ‘X’ for a couple of minutes. 2-3 minutes will be great. By then, some charges would have been transferred to the supposed dead battery. Connect it back to your cordless drill tool and you would notice it working.
When it starts working, turn it off and charge it properly before using. If you use the only the little charges that have entered via the transfer, you are going to kill the battery again.
How do you know if your cordless drill battery is bad?Now, we have been told that if our battery refuses to charge, we can actually take steps to help revive it. While that is true for most cases, you must understand that there is always an end-of-the-road for every battery. In other words, at a point your battery will become bad. No matter how much you to try to revive it at that point, it will not work. So, how can you identify that point so that you don’t waste your time trying to reset the battery?
Follow these steps to find out if your cord drill battery is okay or not;
Connect the battery to the charger and have it plugged to a normal charging point. Leave it for at least 60mins.
After charging it, connect the multi-meter leads to the positive and negative terminals of the battery respectively.
Your goal is to read the voltage that is showing on the meter.
When you see the multi-meter voltage reading a value that is lesser than what the battery is rated at, just know that the battery is done and dusted with.
You should be making arrangements to replace your battery when its voltage drops below its rated value.
ConclusionWhen you plug your cordless drill battery for charging and you notice it’s not charging, it is not the end of the world. You don’t have to give up on the battery just yet or throw it away. We’ve been able to understand via this post that you can reset yours if it is not charging. And we also talked about how your cordless drill battery can get bad and become useless. Learn how to identify a bad battery so you don’t waste quality time trying to revive it.
