Li-Ion and Li-Po Battery Safety & Handling Recommendations

Lithium‑Ion (Li‑Ion) and Lithium‑Polymer (Li‑Po) batteries are widely used due to their high energy density, compact size, and long operating time. While generally safe when used correctly, improper handling, charging, or storage can lead to safety hazards such as overheating, fire, or battery damage. The following recommendations help ensure safe operation and long service life.

Physical and Visual Check

If the instrument or accessory allows physical access to the battery pack, you should inspect it if there is any suspicion of failure or performance degradation, after a shock, drop, impact or overheating event, or after long storage periods. Visually, a bad Li-Ion or Li-Po battery pack is most commonly identified by swelling, puffing or pillowing, losing its flat, rigid shape and may feel squishy. Other warning signs include:

• Any sweet, pungent, or metallic smell, electrolyte leakage, or white powdery residue on the cells or on the walls of the battery compartment.

• Unusual overheating of the battery pack or battery compartment.

• Physical damage like dents or creases, broken or frayed wires.

What to Do if You Suspect that a Battery is Damaged?

Stop using the test set, unplug it from the AC/DC adapter, store it in a non-flammable container, and contact us or our authorized local partner. Provide pictures, serial numbers and thorough description of the symptoms.

• Do not charge damaged or swollen batteries. Discontinue charging immediately if unusual heat, odor, or deformation is observed.

Notes:

• Battery charging and discharging (capacity) performance may be temporarily impacted by exposure to cold weather.

• Battery warranty coverage is typically limited to a maximum of one year, regardless of any extended warranties purchased for the instrument or accessory. For complete details, refer to the official VeEX warranty policy.

Dos and Don'ts

• Replace aging batteries when their usable capacity has noticeably decreased. The overall service life of rechargeable batteries is influenced by environmental conditions and usage patterns. As a guideline, plan to evaluate and typically replace battery packs after approximately three years of operation.

• Always use the AC/DC charger supplied by VeEX for the specific product.
• Inspect batteries regularly for signs of physical damage, swelling, cracking, puncture, or leakage. If damage is suspected, stop using the battery immediately and contact us.
• Avoid short circuits. If you carry or store spare batteries, keep their electrical terminals protected from metal objects, tools, or conductive materials that could bridge contacts and cause overheating or fire.
• Do not store batteries in a fully charged or fully discharged state for prolonged periods. If they will not be used for some time, maintain them at around 40% charge.

• Do not use any battery pack if its plastic enclosure shows signs of impact, shock, cracking, punctures, bulging, or overheating.

• For long-term storage, keep test sets and/or batteries in a fire safe environment or enclosure. Modern Li-Ion and Li-Po batteries are considered safer than ever; however, they are still high-energy components and need to be handled accordingly.

• Avoid purchasing test sets or battery-powered accessories from unverified or informal markets. Instead, contact our authorized local partners for validated product options. If you acquire equipment from secondary or online marketplaces, perform a comprehensive battery inspection and feel free to contact VeEX with the model and serial number. We may be able to confirm the legitimacy of the owner or seller and confirm the age of the test set and its battery pack.

• Do not disassemble or modify Li‑Ion or Li‑Po batteries. Battery packs contain internal protection circuitry and sealed cells that must not be serviced by users.
