Storage Tips for Power Tool Batteries
Store batteries in cool, dry places.
Proper storage is one of the most important actions you can take to extend the life of your power tool battery. High temperatures and moisture are the top culprits that cause battery damage. Storing your battery in a hot or humid place can degrade its internal parts. This reduces capacity and shortens battery life.
Understanding Temperature Limits for Different Batteries
- Lead-acid batteries
You can charge and discharge it between -4°F and 122°F. At 0°F, a lead-acid battery may only provide half of its capacity. - NiCd and NiMH batteries
You can charge it between 32°F and 113°F and discharge it between -4°F and 149°F. - Li-ion batteries
You can charge it between 32°F and 113°F and discharge it between -4°F and 140°F. - Alkaline batteries
The recommended operating temperature range is between -18°C and 55°C.
In general, most batteries perform best between 59°F and 95°F (15°C and 35°C). Temperatures below this range can reduce a battery’s capacity and power output. Temperatures above 25°C (77°F) can raise capacity. But, they also increase self-discharge and shorten battery life.
Batteries can experience major problems at temperature extremes, such as below 40°F (4°C) or above 100°F (38°C). A fully discharged battery can freeze at under 40°F (4°C). So, it needs charging right away.
Batteries that are poorly made may fail to withstand the heat and high discharge rate. They could be permanently damaged.
How Moisture Can Damage Your Battery
Moisture is another factor that can wreak havoc on your power tool batteries. Moisture can rust and corrode the battery’s internal parts. This can cause malfunctions or total failure. Always store your power tool battery in a dry place, away from damp areas like basements or outdoor sheds. Consider using silica gel packets or dehumidifiers in humid storage areas.
Remove Batteries During Storage
If you’re not using your power tool for an extended period, it’s best to remove the battery. Storing the battery inside the tool can strain both. This is especially important when storing your tool for the winter months or when you’re not using it for weeks.
Utilize Storage Mode or Maintain a 40-50% Charge Level
If you store your power tool battery for over a month, use storage mode (if it has it) or keep a 40-50% charge. Keeping the battery at full charge or letting it die can damage it. Maintain the battery at a partial charge. It will stay healthy. This will avoid issues when you need to use it again.
How to Use Storage Mode Effectively
Most modern lithium-ion batteries come with a built-in storage mode. This feature will keep the charge at 40-50%. It prevents overcharging and deep discharging, which can shorten the battery’s lifespan. If your battery doesn’t have this feature, it is up to you to monitor and maintain the proper charge level.
Monitoring Charge Levels During Storage
If you don’t have a storage mode option, regularly check the charge level every few months. Recharge your battery to the 40-50% range if necessary. This will keep the battery’s cells in a healthy state and help maintain its performance over time.
Avoid Common Battery Usage Mistakes
Choosing the Right Battery for the Job
One of the most common mistakes is using a low-power battery (e.g., 2.0 Ah or 4.0 Ah) for high-power tools that demand more energy. An underpowered battery can cause frequent recharges and overuse. This will quickly wear out the battery. When possible, choose a battery with a higher amp-hour (Ah) rating to match the power demands of the tool.
Use the Right Charge
Another key to extending your power tool battery is using the right charger and methods to charge it.
Avoid Overcharging
Avoid leaving your battery on the charger once it’s fully charged. Overcharging can generate heat. This harms the battery’s cells and shortens its lifespan. Most modern chargers shut off when the battery is full. Still, it’s a good habit to unplug the battery when it’s fully charged.
Don’t Deplete Fully
Do not let lithium-ion batteries fully discharge before recharging. It can cause stress on the battery’s cells, reducing its overall lifespan. Instead, recharge your battery when it reaches about 20-30% to maintain its health.
Avoid Frequent Short Charges
Frequent short charges may be less harmful than deep discharges. But, they can still impact the battery’s performance. Always aim to recharge the battery to a full charge when possible.
Use the Correct Charger for Your Battery Type
Always use the charger designed for your specific battery type. Using the wrong charger can result in improper charging and may even damage the battery. If in doubt, check the manufacturer’s recommendations for the charger and battery.
Avoid Overheating the Battery
Overheating is one of the quickest ways to degrade a power tool battery. To avoid overheating, always use the battery within the recommended temperature range. If the battery becomes too hot during use, take a break and let it cool down before continuing.
Underusing or Overusing the Battery
Underusing and overusing your power tool battery can both cause harm. Using the battery only for brief periods may shorten its lifespan. It may not reach its longest lifespan if you don’t fully deplete it. However, overusing it for long periods can strain the cells. Balance your usage to avoid both extremes.
Match the Task to the Battery
Different tasks require different levels of power. Match your tool’s task with the appropriate battery to avoid unnecessary strain. If you’re using a high-power tool, opt for a higher-capacity battery.
Advanced Battery Care Tips for Professionals
Over time, batteries can become out of sync with your power tool. Battery calibration is the process of fully charging and discharging the battery. It ensures the tool’s power settings match the battery’s actual capacity. Calibrating your battery can help. It ensures your tool works well and the battery stays in sync.
Battery Reconditioning: Is it possible to recondition batteries?
Battery reconditioning revives a battery that has lost some capacity. Reconditioning techniques can improve a battery’s efficiency and lifespan. They may not restore it to its original performance, though. However, if someone damages a battery or it becomes very worn, reconditioning may not work.
Using Smart Chargers
Smart chargers are an investment worth considering for professionals. These chargers automatically detect the battery’s charge level. They adjust the charging rate to prevent overcharging and heat buildup. They can alert you to battery issues that need attention.
Frequently Asked Questions (FAQs)
- Can I use a non-brand charger for my tool batteries?
It’s always recommended to use the charger that comes with your power tool. Some generic chargers may work, but they could damage the battery or shorten its life.
- It is not possible to remove the adverb.
Lithium-ion batteries don’t need full discharges. In fact, it’s best to recharge your battery when it reaches 20-30% capacity to preserve its life.
- Is it safe to charge batteries overnight?
It’s generally safe to charge your battery overnight. Just ensure the charger shuts off when it’s fully charged. But, it’s still a good practice to avoid leaving the battery on the charger for extended periods.
- What’s the average lifespan of a power tool battery?
A lithium-ion battery lasts about 2 to 3 years, or 500 to 1,000 charge cycles, depending on usage and care.
- Can I leave my battery on the charger?
It’s best not to leave the battery on the charger once it’s fully charged. Overcharging can lead to overheating and damage.
- Can you recondition an old or dead battery in a cordless drill?
In some cases, technicians can recondition old or dead batteries. We perform a series of full charge and discharge cycles to do this. However, this may not always restore full functionality.
- Can I store my power tool battery in the garage during the winter?
Storing batteries in extreme temperatures is not recommended. Store your power tool batteries in a cool, dry place to maintain optimal performance.
