Drill batteries are a crucial component of any power tool kit, as they allow for cordless movement and increased convenience during various projects. However, just like any rechargeable battery, drill batteries can sometimes fail to charge, leaving us frustrated and wondering if they can be brought back to life. In this article, we will explore some effective techniques and strategies for reviving a drill battery that fails to charge. Read on to find out how to potentially extend the lifespan of your battery and save yourself the trouble and cost of replacing it.
Understanding the Common Causes of Battery Failure
1. Age and Wear:
Over time, drill batteries can exhaust their useful life and succumb to wear and tear. As batteries age, they gradually lose their capacity to hold and store energy efficiently, resulting in decreased charging capability and eventual failure.
2. Memory Effect:
Memory effect is a phenomenon that can cause drill batteries to falsely perceive a lower capacity or charge level than they actually have. This occurs when batteries are consistently recharged before they are entirely depleted. Over time, the battery “learns” to adapt to the shortened charging cycle, resulting in a reduced usable capacity.
3. Over-Discharge:
Allowing a drill battery to discharge completely before recharging can damage its cells and lead to charging issues. Over-discharge occurs when the battery is drained beyond a certain threshold, causing irreversible damage and potential failure to charge.
Techniques for Reviving a Non-Charging Drill Battery
1. Physical Inspection:
Before attempting any revival techniques, thoroughly inspect the battery for any signs of physical damage or corrosion. Look for cracked or swollen casings, loose connections, or any visual indications that may have contributed to the charging failure. If any of these issues are present, it may be best to replace the battery.
2. Deep Discharge/Reconditioning:
When faced with memory effect or over-discharge, deep discharge and reconditioning can often help restore a non-charging drill battery. To do this, fully deplete the battery’s charge by using the drill until it stops working. Once discharged, leave the battery untouched for 24 hours, and then attempt to recharge it fully using the appropriate charger. Repeat this process several times, which can help reset the battery’s memory and potentially restore its charging capability.
3. Freezing Method:
The freezing method is a more drastic approach to revive a non-charging drill battery, but it can yield successful results for certain battery types. Wrap the battery in a plastic bag or wrap it with cling film, ensuring a tight seal, and then place it in the freezer for 12-24 hours. Afterward, thaw the battery to room temperature and allow any condensation to evaporate. Attempt to recharge the battery using the appropriate charger. Freezing can help break down crystalline formations that may have developed within the battery, potentially restoring its charging capabilities.
4. Safe Handling and Charging Practices:
Preventative measures can go a long way in prolonging the life of your drill battery. Avoid over-discharging the battery whenever possible and follow manufacturer instructions for proper charging and storage. Ensure you are using the correct charger that is compatible with your specific drill battery to reduce any potential damage.
While reviving a drill battery that fails to charge is not always possible, attempting these techniques can sometimes yield positive results. By understanding the potential causes of battery failure and implementing safe handling and charging practices, you can prolong the lifespan of your batteries and mitigate the need for frequent replacements. Remember, if all else fails, it may be best to invest in a new battery to ensure optimal performance and reliability during your projects.
