Keep away from children. Review ALL of the additional risks, requirements, recommendations and responsibilities. This potential is aggravated if batteries are damaged, contain an undetected factory defect, are used or stored at temperature extremes, or are approaching the end of their useful life.
See useful life Ideally, batteries should be recharged within 24 hours of a full discharge. The BMS protects the battery from overcharging, high self- discharge or imbalanced charging of the cells, any of which can present the possibility of fire during recharging. Lithium-Ion polymer battery chargers provide a specific charging voltage and microprocessor current and voltage control. Charging should be performed in a fire-safe area, away from children or pets.
For maximum safety, a metal trashcan with lid placed on a non-flammable surface is suggested. Never charge batteries unattended, or where objects such as carpet, furniture, wood or vinyl floors, curtains or other flammable objects are present. Do not attempt to charge a battery that is swollen or bulging. Use only supplied charging cables and connections. Defective batteries have a significant thermal risk and deteriorated mechanical integrity Damaged batteries can go undetected due to prompt voltage recovery and insignificant local temperature increase Example: My cell phone still charges, Laptops getting slightly warm to the touch The battery may be swollen, bloated with cracks, leaking, or have corrosion or burn marks.
Handling Damaged Lithium Batteries. Do not use damaged batteries. If currently installed, remove from device. If you are unable to remove the device safely and easily, keep the battery in the device and recycle the entire unit. To recycle a damaged battery, purchase one of our DDR kits. Do not put a damaged battery in the trash; this is a common cause of fires in garbage trucks and recycling facilities.
Remove damaged batteries from use and send for reclamation. Thermal Runaway. How it Happens. Faulty cell design Cell manufacturing flaws External abuse of cells Inefficient battery-pack design Poor protection design Inadequate charger or charging system design.
Common Damage Types. There are three common damage types that lead to lithium battery failures:. Mechanical Thermal Electric abuse. Avoid mechanical, thermal, and electric abuse:. Early Failure Symptoms. Change in charging efficiency, charging and discharging cycle inefficiency Battery heating during charging, particularly near the end of charging Charging capacity is higher than discharge capacity beyond the typical charge efficiency losses.
Recycling Lithium Batteries. Li Batteries are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would. If a Li Battery completely discharges the battery is ruined. A Li battery pack must have an onboard computer to manage the battery.
This makes Li Batteries more expensive than they already are. Has a recent catastrophe affected you? Get In Touch. Share Facebook Twitter LinkedIn. Print or Download Print Download. Learn More About Michael J. Back to the Knowledge Center.
If they touch other metal surfaces, you may have a short circuit situation. Your single-use, alkaline batteries — think AAA, AA and 9-volts — have occasionally caused fires as well.
If you're unsure which battery you're working with, tape up the ends just in case. Many recycling plants have special certifications in reusing or disposing of electronic waste, which include data security procedures, said Plummer.
