Are Dewalt batteries fully charged when I buy them?
While Dewalt batteries are typically shipped with a partial charge, they are not fully charged upon purchase. Most manufacturers, including Dewalt, prefer to ship batteries in a state that preserves their lifespan and performance. Therefore, you might find that your new Dewalt battery is around 30-60% charged when you first unwrap it.
To ensure optimal performance, it is recommended to charge the battery fully before your first use. This practice helps calibrate the battery and can extend its longevity. Always check the provided charge indicator on the battery, if available, for a better understanding of its current charge status.
How can I check the charge level of my Dewalt battery?
Dewalt batteries often come equipped with a charge level indicator, which can be a useful tool for gauging how much power is left. Typically, this indicator is a series of lights that will illuminate based on the remaining charge. You can press a button on the battery to see how many lights are lit, giving you a quick visual representation of its charge level.
If your battery does not have an indicator, or if you want to be doubly sure of its charge, you can simply install it into a compatible Dewalt charger. Most chargers show the charging status, including whether the battery is fully charged or still requiring some charging time.
What should I do if my Dewalt battery doesn’t hold a charge?
If your Dewalt battery is not holding a charge, first check if there are any visible signs of damage, such as cracks or leaks. If the battery appears undamaged, try charging it again using a Dewalt charger that is known to work properly with other batteries. Sometimes, the battery may simply need a little more time to charge, especially if it was deeply discharged.
If the battery still fails to hold a charge after several attempts, it could indicate a deeper issue, potentially requiring battery replacement. In such cases, referring to the warranty or contacting Dewalt customer service for guidance on troubleshooting or replacement options may be the next best step.
