Poynt GoDaddy Terminal: Battery Swelling Diagnostic... | terminalfaults.org

Technical Background:

Lithium-ion battery swelling is caused by gas generation due to electrolyte decomposition. This process is accelerated by overcharging, deep discharging, excessive heat, physical damage, or manufacturing defects. The internal resistance of the battery increases as it degrades, leading to heat generation during charging/discharging. Cold temperatures (-30°C) can increase internal resistance and reduce battery capacity, exacerbating the effects of degradation.

Symptoms:

Observed swelling of the terminal's battery. This indicates potential internal cell degradation and gas production.

Possible Causes:

Overcharging: Continuous charging after the battery is fully charged.
Deep Discharging: Allowing the battery to repeatedly drain to very low voltage levels.
Excessive Heat Exposure: Although -30°C is not excessive heat, prior heat exposure could have damaged the battery.
Manufacturing Defect: A pre-existing flaw in the battery cell construction.
Age of Battery: Degradation of battery chemistry over time.
Incompatible Charger: Using a charger with incorrect voltage or current specifications.

Solution:

1

Immediately disconnect the terminal from its power source using Safe Handling procedures (unplug the power adapter).
2

Remove the terminal from service to prevent further use.
3

Document the issue with photographs and detailed notes for warranty claims.
4

Contact Poynt or GoDaddy support for a replacement terminal or battery service, adhering to their return merchandise authorization (RMA) process.
5

Store the affected terminal in a fire-resistant container in a well-ventilated area away from flammable materials until proper disposal can be arranged.
6

Follow local regulations for disposal of lithium-ion batteries; do not dispose of it in regular trash.
7

Examine the power adapter for damage or incorrect voltage/current ratings.

Safety Warning:

Swollen lithium-ion batteries pose a fire hazard. The battery can rupture and release flammable gases. Avoid applying pressure to the battery or exposing it to heat or open flames. Static discharge (ESD) is heightened in -30°C weather, so ground yourself before handling the terminal. If the battery is actively smoking or emitting fumes, evacuate the area and contact emergency services. Do not attempt to extinguish a lithium-ion battery fire with water; use a Class D fire extinguisher (for metal fires).

Prevention:

Avoid leaving the terminal plugged in continuously after it reaches full charge.,Prevent the battery from being deeply discharged; recharge when the battery level is moderately low.,Ensure the terminal is used within its specified operating temperature range.,Only use the manufacturer-supplied power adapter or a certified compatible charger.,Implement a battery health monitoring system (if available) to track battery performance.,Periodically inspect the battery compartment (externally) for any signs of swelling or damage.,Train staff on proper charging and handling procedures.

Expert Tip:

Check the power adapter's output voltage and current against the terminal's requirements. A mismatched power adapter is a common cause of battery problems. Some USB-PD chargers may negotiate the wrong voltage, causing the battery to swell. Also, verify the integrity of the charging cable, replacing it if damage is observed.
