FM-05: 套装BATTERY无法开始或完成充电

V20battery电池包在室温下放入批准的充电器时无法开始充电或无法完成充电。充电器可能无指示或无限期保持充电状态。

• Battery is not fully seated in the charger
• Outlet or charger has no power or blocked ventilation
• Battery is outside the permitted temperature range
• Battery or charger has internally failed

1. Charging starts and completes normally, or reciprocal testing conclusively identifies the external battery, charger, or service endpoint.

1. Let the battery and charger reach room temperature, then seat the pack fully and observe the charger indication.
2. Cross-test a known-good V20 battery in the original charger and the original battery in a known-good approved V20 charger.
3. Replace only the proven failed external counterpart or use authorized service; never open the battery or charger.
4. Remove the battery from the charger and inspect the pack, charger, cord, and contacts for liquid, swelling, cracks, melting, burning, or impact damage.
5. Prove the outlet, plug in the charger directly, keep its vents clear, and dry-clean only accessible contacts.
