How to enhance Cordless Drill battery life?

To enhance the cordless drill battery life, you need to take the following measures.

Regularly use battery

This fact is true with almost all batteries lack of usage decreases the battery life. If you rarely use your cordless drill, you may need to keep it plugged in or completely recharge the battery before going on a project.

Keep Battery Fully Charged

If you want to use the cordless drill for longer hours, try to keep it fully charged. Most batteries last longer if we recharge them before they reach below 70% capacity. But that’s not the case with every battery, and if you hold a NiCd battery, you need to completely discharge them once a week to increase their average battery life.

Keep Battery Cool and Dry

If you want to enhance the cordless drill battery life, try to store it in a cool and dry place. But never attempt to store them in the freezer as it can damage the batteries.

Use Right Cordless Drill Settings

This is the most important way to enhance cordless drill battery life. Be sure to use the right tool settings to accomplish your job. Keep in mind that the higher torque settings consume more battery and, as a result, can affect the overall battery life.

Protect it Properly

Another way to enhance the cordless drill battery life is to gently handle it. Keep in mind that the damaged or cracked batteries have lower battery life. If you want to enhance the battery life, try to store the cordless drill battery in a cushioned bag or original carrying case. And always use the plastic cap to prevent any short-circuiting and to protect the battery terminal from moisture or breakage.

Can you leave a drill battery plugged in all the time?

The quick answer to this question is “NO.” Keeping the drill battery plugged in all the time can severely damage the battery and shorten its life.

Almost all the cordless drills come with an instructions booklet to teach the users how to perfectly charge the battery and how much time you can keep plugged in while charging or working. If the tool instructions allow you to store the battery on the charger, never forget to remove it once the battery is fully charged.

If your cordless drill has a Lithium-Ion battery, don’t charge or discharge it completely to maintain the effective battery life. When your Li-ion battery is fully charged, the degradation can be worst.

You can keep the battery plugged in if the charger has an indicator to let you know that battery is full. And some high-end cordless drill batteries are there, which auto-disconnect the charging once the battery is filled.

Overall, keeping the battery on charging without any automatic shutdown options can badly affect the cordless drill battery run time in a way or two. In actuality, leaving the battery plugged in can significantly degrade the battery backup, and hence you will find your battery less operative.
