How to choose the best replacement battery?

There are a lot of things you should keep in mind when making a buying decision. We are making sure you don’t miss any of them while informing you about the reason behind the importance of a particular factor.


The main difference between two batteries is the voltage. Depending on the type of work you are expecting your tool to do, you can choose from a few ranges of voltage.

A battery with 7-12 volts is good for light work only, and for your heavy-duty projects, you will need a battery with 18-36 volts. In between, there are the batteries with 12-18 volts that cover the medium types of work.

The best and most used battery over the years is the 18V battery. But, this has recently changed, after the DeWalt replacement battery with 20V.

Capacity run-time

Battery’s capacity and run-time are something a professional must check on first! You want to get the longest run-time out of your battery and any extra battery life is worth your money. This is why you should consider getting a DeWalt battery. For instance, the 18V XRP Extended run-time Battery pack gives you a 40% more run-time than standard batteries.

Charge times

Of course, the charge time a battery need is very essential for you if you are working a lot and always full of deadlines. Before buying a battery, you should check how long does it take to be fully charged. If you get one of the DeWalt 12V-20V MAX Li-Ion batteries, you should consider buying a 12V MAX – 20V MAX Li-Ion DeWalt charger too. This is the ultimate combo for a short charging time. This charger will make sure you charge your battery within 90 minutes. Plus, it is compatible with every De-Walt 12V-20V MAX Li-Ion battery.


Another factor you should pay attention to is the weight of the battery. You don’t want to hold a heavy tool for a long period, so you should go with as lightweight a battery can be. While making a comparison between some of the DeWalt batteries, we noticed an interesting fact, which is that the DeWalt 20V MAX Li-Ion battery with 5Ah is weighing 1,59lb and the one with 3Ah is just a 0.01lb shy. There is no real difference! This is very important if you need a higher power and don’t want to get a heavier battery.


After taking in consideration the major factors, you should also take a look at the features a battery might have. It could come with or without a LED indicator, a Bluetooth etc. However, you must know that the temperature is highly impacting the performance of the battery. For most of the batteries, 65-90 F is the recommended temperature range. Anything higher or lower than that would significantly impact the lifetime of the battery. And this could result in a permanent damage on the battery and its run-time.

This is one of the reasons why we decided to make this review. Many people are discouraged by the high price of the official replacement batteries. We are aware that they are pretty much expensive and we understand if you are tempted to risk and buy an aftermarket battery. But we are here to make up your mind and don’t let you to make the greatest mistake of your life, when it comes to buying batteries, of course. The aftermarket batteries could explode and physically injure you. These risks are not worth the savings. The tool is also expensive and you shouldn’t risk its lifetime with an aftermarket battery.


This is the first thing the people are asking, when buying a battery. You have to make sure your battery is compatible with your tool. It’s otherwise useless. But we are not worried with this factor so much, because the DeWalt batteries are compatible with almost every DeWalt tool. Especially the DeWalt FlexVolt battery packs! They work in 20V MAX 60V MAX and 120V MAX tools. So, you got nothing to worry about.

Dewalt XR battery compatibility

DeWalt 18v batteries are fully compatible with the whole DeWalt XR range. This translated could mean that if you get two XR batteries that is all you are going to need. The reason behind this is that These batteries have a very fast charging time (under 2 hours) while providing a long usage (more than 3 hours continuous usage). You get to work using one of the batteries, while the other is charging, and when the first one is finished, you have the other prepared to continue the work.

Batteries interchangeable advantages

After pointing out the most important factors for a battery’s performance, we would like to review the interchangeable advantages that make the DeWalt batteries the best. We might have slipped a few hints in the previous section of this review, but this is very important, so we have to be sure you got it right. First of all, the greatest advantage of the DeWalt batteries is that they are all powered by the same battery charger. This is going to save you a lot of money, since you don’t need to buy a charger for each tool individually. Also, if you buy some new tool, this doesn’t mean that you will have to buy new charger. It applies for all, old and new, tools out there. This is an excellent opportunity to power numerous tools with one charger only.

Final Thoughts

Batteries are such an essential part of tool performance. We understand the difficulty you are facing when trying to make up your mind and choose between all the choices out there. Prices can be intimidating and people often risk everything while making some stupid mistakes. That was the reason behind this review and hopefully, we made it clear. Tools are hungry for power and this problem is what DeWalt had in mind when designing and producing the best solutions out there. We recommend that you stick to the branded batteries because the aftermarket ones impose big health risk and possible damages to your tools. Compatibility and power go hand in hand with Dewalt replacement batteries and we cannot stress enough how much satisfied we and all the DeWalt customers are. How can we not be, when all our wishes were heard and they even made the new 60V battery pack backward compatible with their line of 20V Max tools!
