When to Call a Professional

Professional help is also needed if the battery was submerged in saltwater or contaminated liquids.

Frequently Asked Questions

How long does it take for a wet DeWalt battery to dry completely?
Allow 24-48 hours for complete air drying in a warm, dry location. Heavy moisture exposure may require up to 72 hours. Using desiccants like silica gel can reduce drying time to 24 hours.
Can I use a hair dryer to speed up drying my DeWalt battery?
No, never use hair dryers, ovens, or direct heat sources. Excessive heat can damage the battery cells, cause swelling, or create safety hazards. Room temperature air drying is the safest method.
Will my DeWalt battery warranty cover water damage?
DeWalt warranties typically do not cover water damage or moisture exposure, as this is considered misuse. However, if the moisture exposure was due to a manufacturing defect in the housing, contact DeWalt customer service to discuss your specific situation.
Is it safe to use a DeWalt battery that got wet but seems to work?
Only use the battery if it's completely dry and passes all safety checks. Even if it appears to work, internal moisture can cause corrosion, reduced performance, or safety issues over time. When in doubt, have it inspected professionally.
What should I do if my DeWalt battery was submerged in saltwater?
Saltwater exposure requires immediate professional attention. Rinse with distilled water, dry thoroughly, but expect the battery to need replacement. Salt causes rapid corrosion and can make the battery unsafe to use.
