Buyer’s Guide

There are many factors and features in a cordless drill battery that you should keep in mind while making a buying decision. And for that reason, we have listed those factors so that you don’t neglect any of them while conveying imformation about the reason behind the importance of a particular aspect. 

  • Voltage

Voltage is the essential feature that can distinguish between any two batteries, and also it depends on the kind 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 recommended for light projects, and on the other side of you are dealing with a heavy-duty task, then go for a battery that has at least 18-36 Volts. In between, there are also batteries with 12-18 volts that covers the medium types of task.

  • Weight

Another essential factor that you should not neglect is the weight of the battery. You would definitely not want to hold a massive tool in your hand because it is quite uncomfortable, so we would suggest you to go for a lightweight battery as possible. While having the survey, we have noticed a pretty interesting fact: many cordless drills batteries with 5Ah weighing 1,59lb and the other one with 3Ah is just a 0.01lb shy. There is no proper difference, but you have to be very careful and select very technically because, for sure, you need a higher power and don’t want to get a more massive battery as well.

  • Capacity run time

If you are a professional, then the battery’s capacity is something you should not forget to check. Everyone wants their battery to have the longest run time, and believe us, extra battery life worth your money, and we would recommend you consider a DeWalt battery for this purpose. For instance, the 18V XRP Extended runtime Battery pack gives you 40% more runtime than any other standard batteries.

  • Features

After going through all the main points of a battery that you should consider, don’t forget to look at the features a battery might have. Battery with rich features would surely go a long way. You should know that many batteries come with an LED indicator and Bluetooth. Most importantly, it would help if you were equipped enough because the temperature is highly impacting your battery’s performance. For many of the batteries, 65-90 F is the recommended range of temperature. Anything lower or higher than that would significantly impact the lifetime of the battery. And this could even result in permanent damage to the battery and its runtime. 

  • Compatibility

This is usually the first query that pops into a buyer’s mind when buying the battery. You have to be sure that the battery you are planning to purchase is entirely compatible with your cordless drill; otherwise, it is useless to get a replacement. This seems to be quite a crucial factor, but we have still listed this in the last because nowadays when technology has made such advancements, you should not worry about this factor compared to the other. Almost all of the batteries are compatible we practically every tool. So, you got nothing to worry about, but still, this doesn’t mean that you should neglect this. 

Last but not least

Batteries are an indeed essential part of any power tool, and we can completely relate to the effort you are making when trying to make up your mind and choose between all the choices out there. That was the main reason behind this review, and hopefully, we made it clear.

Moreover, we suggest you stick to the branded batteries because the aftermarket ones impose a significant health risk and some possible damage to your tools.

Hopefully, you have found the machine of your dreams. If not, at least you must be equipped with all the necessary information about replacement batteries and are ready to implement that while visiting a market. 

Happy Shopping!!
