Scanner Battery Charging Issue – Cause & Permanent Resolution

Overview

The scanner hardware is fully functional. The issue reported is not related to the scanner itself, but specifically to the battery charging process. Even a new scanner can experience the same issue if the battery recharging procedure is not followed correctly.

Root Cause

Our investigation indicates that the issue occurred because the battery was allowed to drain below 5% charge.

When a lithium battery (18650 type) drops below this level:

• Charging behaviour may become unpredictable
• The scanner may appear unresponsive, even though it is functional

Note: The scanner's battery features internal circuit protection, preventing unsafe conditions. However, when deeply discharged, the protection circuit may prevent normal USB charging until the battery is externally recharged or replaced.

Permanent Solution (One-Time Fix)

To permanently resolve this issue, one of the following is required (only once):

Option 1: Replace the Battery

• Purchase a new 18650 lithium battery
• Replace the old battery inside the scanner

Option 2: Recharge Using a Dedicated Battery Charger

• Purchase a 18650 lithium battery charger

• Recharge the existing battery using the charger

  (Note: Chargers are generally more expensive than replacing the battery)

After completing either option, you can continue charging the scanner normally using the provided USB cable.

Recommended Charger Example

An example of a compatible charger:

• POWXS 18650 Battery Charger – LCD Universal Intelligent USB Lithium Battery Charger (AA/AAA compatible)

This is only a reference; similar 18650-compatible chargers will also work.

Payment & Reimbursement

• If you share the purchase link with us, we can request our accounting team to pay directly, so you do not need to cover the cost.
• If your company already has:
  • An 18650 battery charger, or

  • A spare 18650 battery

    You may use that instead.

How to Access the Battery
