Dremel lite 7760 is a handheld rotary tool that runs on a battery. The best part of this tool is that it’s portable and you can take your craft project anywhere with it. But what if the machine isn’t charging anymore? Well, that’s the concern we are dealing with in this article.
Now the question is, why is the Dremel Lite 7760 not charging? Usually, the problem is either with the charger or the battery. But we’re not looking for a clear answer here and it’s not even that easy. It’s important to figure out exactly where the problem might be and we need to be as specific as possible.
In this article, I’ll discuss the possible reasons why you might be facing this issue with your Dremel Lite 7760. Not just figuring out the problem, my purpose is to cover the possible solutions, and discuss whether the problem is even fixable or not!
So, let’s start!
Why My Dremel Lite 7760 Not Charging?
Considering the common issues that frequently cause this problem, there can be 5 to 8 answers. Sometimes it’s a basic issue that you feel silly for not noticing earlier and sometimes it can be really serious and cost you some bucks. Check out here which issue is causing the problem in your case and what you can do –
Battery Capacity Fade
Dremel Lite 7760 uses a 4V secondary Li-ion battery. Unlike primary batteries, secondary cells can be recharged. However, it does have a limited lifespan. A lithium-ion battery usually has a lifespan of about 3 years (maximum) or about 300-500 charge cycles. After that, the capacity starts to fade.
In theory, a rechargeable battery is supposed to last for a lifetime. But the lithium ions in the battery start decaying for certain reasons. This lithium loss is usually the main reason behind capacity fade. So, if your battery has already lasted more than 2 years, the capacity fade is the possible reason why it’s not charging anymore.
Solution: If that’s the case, you don’t have much to do. Your battery has done its duty and now it is time to get a new one.See if you are new in woodworking: How to Carve Wood for Beginners
The reason why your Dremel Lite 7760 is not charging can be because the charger is out of order. The charger needs to do its job in order to power up the machine again. So, before you reach the conclusion that the battery is the main culprit, make sure to check the charger with a multimeter.
The charger of the Dremel Lite 7760 comes with a USB cable and an adapter. The possibility is high that the issue is not with the whole charger and just the cable or the adapter. So, try using a different cable with the adapter and vice versa — just to be sure!
Solution: If only the cable or adapter is faulty, you can look for spares in the market or order them on Amazon. Better not to use a different adapter or cable if you can find one that’s meant for this tool. If the whole charger is out of order then buying a new one might just be the only solution

Clogged Terminals and Faulty Pins
The positive and negative terminals of the battery need to have a solid connection with the dedicated pins to establish a connection between the charger and the battery. But sometimes the terminals become dirty and in some cases rusty, which interferes with the connection.
In many cases, the reason behind this ‘not charging’ issue is the faulty terminals. If a pin is broken or damaged, it won’t be able to secure a solid connection. Unnecessary pressure while inserting the battery and misplacement can be the reason why the pin is damaged.
Solution: Use alcohol and cotton swabs to clean the terminals and pins. Don’t use water as it can cause a short circuit or even worse. If a pin is broken then take it to a technician. A technician might be able to make it work again but that won’t be sustainable.

The Battery & Charger Is Not Properly Connected
As I said earlier, the reason behind the whole fuss can be just a silly one. Sometimes the reason your rotary tool is not charging is that the connection between your charger and the battery is not right. It can happen when you’re trying to insert the battery in a rush.
Solution: Make sure that you hear a ‘click’ sound when you insert the battery into the case. Also, check if the USB cable is properly inserted into the adapter and whether the charger pins are only halfway through.

Are you sure that the outlet you’re using is working properly? If electricity isn’t passing through the outlet, it won’t be able to charge the machine. And sometimes even if you can detect electricity in that line, maybe it’s not enough to charge the Dremel Lite 7760.
Solution: Try using a different outlet and see if the machine is charging again. If your rotary tool is charging with a different outlet then the problem is obviously with the outlet.

May Be The Battery Is Dead
If your battery is dead, it surely won’t charge! Capacity fade and dead battery are completely two different things. Capacity fade is more like dying of old age while a dead battery is similar to an untimely death in an accident! Your battery can go out of order for a lot of reasons.
Temperatures, power surges, and short circuits are usually the factors that cause this problem. The battery can also get seriously damaged if you drop it on the ground.
Solution: There is nothing you can do about a dead battery. ‘Jump start’ can be a solution but it will rather have serious effects on a small-size battery such as the one in Dremel rotary tool.
