Your Bad (or Misinformed) Habits are Killing Your Power Tool Batteries

When asked which power tool brand someone should go with, most pros and experienced DIYers will drive home the importance of battery power, battery life, and availability before they mention special features, speeds, or durability. That’s because, without reliable batteries, the tool extras don’t matter.

1. Leaving Batteries on the Charger

One of the most common ways DIYers kill their batteries’ potential lifespan is by keeping them on the charger. This can cause overcharging, which will result in a drastically shorter usable lifespan. A better course of action is to remove batteries from the charger when they’re ready and store them properly (more on that in a bit).

2. Storing Dead Batteries

On the opposite end of the spectrum from overcharging, putting dead batteries away for long periods will also kill their capacity to hold a charge over time. You can avoid this by swapping to a new battery before the first one dies, or simply charging dead batteries for 20 minutes before storing them.

3. Completely Draining Batteries

If they’re not paying attention, it’s very easy for a DIYer to run a battery down until it’s completely dead, but deep drains aren’t good for modern battery chemistry. Also, with older nickel-cadmium batteries, it was recommended to drain them completely before storage. That’s not the case anymore.

4. Storing Batteries That Are Fully Charged

At this point, it might seem like batteries are the Goldilocks of the tool world, but you should not store batteries fully charged. First, fully charging a battery will shorten its lifespan. Second, a fully charged battery exposed to high temperatures is more likely to degrade or explode.

5. Not Storing Batteries Properly

There is more to storing a battery than simply throwing it in a tool box at 50 percent of its charge. Battery packs are full of electronics, individual energy cells, and wiring. Allowing them to bounce around in the bed of a truck or tossing them from shelf to shelf in a workshop will cause the kind of damage that shortens their lives.

6. Exposing the Battery to Extreme Heat

Extreme temperature are not good for battery packs, and extreme heat is the worst. Temperatures in excess of around 80 degrees Fahrenheit will degrade a battery, with temperatures above 100 or 120 degrees Fahrenheit causing rapid damage. For that reason, it’s best to store batteries in a garage that remains relatively cool during the summer.

How to tell if a battery is charged?

Check the voltage reading on the multimeter. The reading should correspond to the battery’s total voltage (usually indicated on the battery) to indicate that the battery attained a full charge for a well functional battery.

Why is my cordless phone battery overheating?

One of the most emphasized maintenance practices for cordless phone batteries is storing them in a cool, dry place. Exposing the battery to a very high temperature will most likely result in overheating. Excessive charging is also a probable cause. Overheating may cause malfunctioning and, in the long run, compromise the battery’s ability to hold charge efficiently.

How long do batteries last in cordless phones?

Rechargeable batteries in cordless phones are designed to last for up to three years. However, their longevity largely depends on whether or not you handle the battery with care. Proper maintenance practices such as storing the battery at room temperature can go a long way in extending your cordless phone’s battery life. However, the battery tends to rapidly lose its ability to hold a charge without these practices and may last for barely one year.

How long does a cordless phone battery last?

Most cordless phones feature up to 1000 cycles, which can last for about twelve months. It is therefore advisable to replace your cordless phone’s battery after every twelve months.

Why does my phone keep charging?

Having to constantly recharge your phone’s battery within short intervals due to rapid discharge is a sign of a faulty battery. Some cordless phone models use nickel-cadmium (NiCad) batteries, which are prone to memory effects. Due to the memory effect, failure to completely use up your battery before recharging compromises its runtime since the battery becomes unconscious of the unused percentage.

How to keep a cordless phone charged?

You can guarantee effective charge retention by placing your cordless phone in its charging place or cradle. The cordless phones are characterized by a recharge indicator that will help you determine the strength of the battery while the phone is out of the cradle.

Why is my phone battery swollen?

Battery swelling is often a result of overcharging your phone or repeatedly using an incompatible charger. If your cordless phone battery is swollen, it is advisable to avoid using your phone in that state. Fortunately, the problem can be easily resolved by a phone technician.
