Understanding Intermittent Charging in Power Tools

Ever plugged in your drill or saw only to find the battery charging light blinking like a confused traffic signal? Intermittent charging isn''t just annoying – it''s a productivity killer. Let''s break down why this happens and how to solve it.

Top 5 Causes of Tool Battery Charging Issues

• Dirty Contacts: 62% of charging failures stem from oxidized terminals (2023 PowerTool Maintenance Report).
• Thermal Runaway: Batteries stop charging when internal temps exceed 45°C.
• Adapter Mismatch: Using 18V chargers with 20V batteries reduces efficiency by 40%.
• Cell Imbalance: Common in Li-ion packs over 2 years old.
• Software Glitches: 1 in 5 "smart" batteries require firmware updates annually.

"Modern battery management systems can reduce charging errors by up to 80% compared to traditional methods." – Energy Storage Technology Journal
