Power Tool Battery Life Review

If you have bought any type of cordless tool, including a cordless drill, then the most important part of that will be the battery. There may be plenty of features on your drill, but without a reliable battery to power it up, the drill is pretty useless.

There is no doubt that cordless drills are a great thing to have as they just make everything that much easier to do. If you look after the power tool battery properly, then it will last for several years, before it needs replaced.

Types of Cordless Drill Batteries

if you would like to find out about the different types of batteries available for your cordless drill, then please click here to read a detailed article on the choices available. This particular article is about how to look after them and help extend their useful life.

We all know that these batteries are not cheap, so we will want to maximise their life span.

A typical stand alone battery costs on average around $40 so these are not cheap. By taking just a little care you can easily add a year of life to your battery, and at the end of the day, that will save you money.

General Care of Cordless Batteries

It may sound obvious to keep your battery charged, but unless the drill is being used regularly, then most people forget about it until the next time they need to use it.

That is not a good thing in terms of ensuring a long life. Batteries need to be charged and used regularly as that will help keep them functioning to their maximum capacity. Ideally a battery will charge best when it is around 70% of its capacity.

The Complete Discharge Theory

You may have read that you should not charge a battery until it is fully discharged. That is not actually true. You only need to do that about once a month and at all other times you can charge it as and when you may need to use it.

Always allow your battery to FULLY charge – When you do have to give it a quick charge, then leave it plugged in until it is fully and completely charged.

There is often a strong temptation to stop the charging, especially if you are in a hurry to finish a job, but it is strongly advisable to wait a few minutes and make sure the cordless drill battery is 100% charged. That practise alone will really add a lot of life to your battery pack.

It is why we here at Tool and Go recommend always having 2 batteries. You can be using one and allow the other spare battery to fully charge. If you are someone who uses power tools every day, I am guessing you already have worked out that having two batteries is just a great idea.

Lithium-Ion batteries should in theory work forever because they work on the movement of ions. However, like any product, their general treatment and care, temperatures and aging process will also have an impact on these type of batteries.

Storing Your Cordless Drill Battery

Like any battery the life of it can be maintained if the battery is stored in a dry environment. I have seen many batteries left in cold damp garages or workshops, and not looked at for weeks, maybe even months. That is not a good thing to do at all.

If possible store your batteries in a cool dry place. if you got a bag or a case with your cordless drill, then it only takes a few seconds to pop the battery back in there and it will keep it safe.

If you plan on storing your battery away for a few weeks or months, then the ideal charge should be around 40% as at this charge, the drill battery will last longer.

Should you remove the battery from the drill when not in use?

This is a question that we are asked all of the time. We look at many manuals on a weekly basis, and we have tried removing the battery and also leaving it in the drill. We have not found anything that makes a recommendation either way. Our testing has also shown that there was no difference either way by leaving it in place, or taking it out and storing it in a separate place.
