Why Won't My Battery Charge? Common Fixes

Battery Won't Charge — Start Here

A WorCraft 20V battery that won't charge is usually caused by one of a handful of common issues — most of which you can resolve on the job without sending anything in for service. Work through these checks in order before contacting support.

Check 1: Charger Connection

  • Make sure the charger is fully plugged into a working outlet. Test the outlet with another device.
  • Reseat the battery pack in the charger — press it down firmly until it clicks. A loose connection is the most common cause of a "no charge" symptom.
  • Check the charger indicator light. If it's solid red, the pack is charging. If it's flashing or off entirely, continue below.

Check 2: Battery Temperature

WorCraft 20V batteries have a built-in thermal protection circuit. If the pack is too hot (just pulled from heavy use) or too cold (stored in a cold vehicle overnight), the charger will not begin charging until the pack reaches a safe temperature range of approximately [X]°F to [X]°F.

  • Too hot: Let the pack cool at room temperature for 15–30 minutes, then retry.
  • Too cold: Bring the pack indoors and let it warm to room temperature before charging.

Check 3: Battery Contact Condition

Inspect the battery terminals and charger contacts for dust, debris, or corrosion — especially common in stone and tile fab environments. Wipe contacts with a dry cloth. Do not use water or solvents on battery contacts.

Check 4: Deep Discharge

A battery that has been fully depleted and left discharged for an extended period may enter a protection state that prevents normal charging. If the charger shows no response after 5 minutes, try a different WorCraft charger if available. If the pack still won't charge, it may need replacement.

Check 5: Charger or Battery Fault

If the charger indicator flashes in an error pattern (see your charger manual for flash codes), either the charger or battery has detected a fault. Try a known-good battery in the same charger, and a known-good charger with the problem battery, to isolate which component has failed.

FAQs

Q: Can I charge a Makita battery with my WorCraft charger?
A: No — the WorCraft charger is only compatible with WorCraft 20V battery packs. Charge Makita packs with a Makita charger.

Q: My battery charges but drains immediately — is it dead?
A: A pack that charges but loses power quickly has likely reached end of life or suffered cell damage from heat or deep discharge. Contact WorCraft support to check warranty coverage. See warranty info.
