Black and Decker have become a cornerstone brand in the competitive DIY/tools market. These things don’t happen by accident, either.
To really rise to the top with this discerning and knowledgeable customer base, you need to provide tools that are user-friendly, highly-effective, powerful, and reliable – all at the same time. Either that, or your brand won’t stick out from the rest.
This is precisely why we were so surprised when we read that quite a few of you were having troubles with your lithium battery chargers. So, we’ve set out to try and fix it.
How Do I Stop My Black and Decker Lithium Battery Charger Flashing Red?
What is most maddening about these sorts of problems for us is that it should all be much simpler. How difficult is it to design something that charges a battery effectively and reliably, especially after you have mastered the complex design of the tool itself?
What makes this a lot more confusing for us is that we simply could not isolate any single factor that could be causing the problem.
But this does not mean that we haven’t found a few ways around this problem. We’ve tested these methods out and noticed that some of them will work for one person while others will work for different people.
Again, there just doesn’t seem to be a single cause for the issue that we can shift the blame onto. Regardless, if you’re as annoyed as we are with your flashing red lithium battery charger, here’s a few tips to help you sort it out.
1. The battery may just be too hot
As always, we’re kicking our guide off with the simplest solution first. That way, you might not have to go all the way to the end when something straightforward could have been mentioned at the start.
Lithium batteries, when they get too hot, simply will not take a charge. Though the flashing red light can also signify other problems, it can also be taken to mean that you need to let the battery cool down a bit before you try to charge it.
Ideally, we would recommend that you wait for at least 30 minutes before trying to charge it. That should be ample time to rule this cause out. If it still won’t charge after that amount of time resting, the problem lies elsewhere. On to the next tip!
2. Your charger may be faulty
The next most likely cause of the issue is that your charger may just be a little faulty. It’s strange to think that a brand as reputable as Black and Decker could make a mistake here, but these things do happen from time to time.
What is most likely happening here is that the battery either isn’t getting exactly the right voltage it needs to charge or the battery itself is warming up way too quickly, triggering the flashing red light.
To rule this out as a cause, we would suggest that you try and connect the lithium battery to another charger, if there is one available to you. Then, if it starts charging as normal, this would indicate that the problem is most certainly with the charger you have bought. In this case, it is likely that you can get a replacement under warranty.
3. An issue with the battery itself
If you are seeing a rapid succession of blinking red lights on the battery, there is a chance that you have simply purchased a faulty one. Unfortunately, the news isn’t good if you have.
There really isn’t anything you can do to repair a lithium battery. Even if you have the option to have it repaired with a professional, we wouldn’t recommend it. Repaired batteries tend to develop all sorts of problems in a relatively rapid timeframe.
The sad fact is that the only logical course of action to take care of a faulty battery is simply to replace it. Before doing so, we would still recommend that you read on and make sure you have tried every other available course of action.
4. Get in touch with customer support
It may seem like it could be a waste of time. But, getting in touch with customer service is always recommended when you encounter problems such as these.
More often than not, they will be able to give you an extra troubleshooting step or two that we may not have been aware of. Alternatively, they may have received authorisation to simply offer replacements.
In any case, your best bet is to write up a detailed ticket that explains everything that you have tried to fix the issue so far. That way, they won’t be advising you to repeat anything you’ve already done, saving time on both sides.
The Last Word
So, there you have it! These are essentially the only tips we could come up with for a problem that seems to have no exact cause. We hope that these steps helped you out and that you either figured it out for yourselves or managed to get a replacement sent out.
