If your Li-ion batteries are approaching the end of their lifespan, they can pose hazards within your workplace. Although this type of battery is renowned for its longer lifespan compared to other batteries, such as lead acid batteries, there is a limit to the number of charging and discharging cycles they can safely undergo. If your batteries have been extensively used, it is advisable to establish an inspection and disposal system to remove your aged batteries from daily usage.

Aged batteries are more susceptible to deterioration and damage, which can result in issues such as overheating and battery fires.

Given the increased prevalence of this battery type in both workplaces and households, there are numerous environmentally-friendly recycling options available throughout local. It is recommended that you consult your local recycling organization to determine the most suitable method for recycling your end-of-life lithium-ion batteries.

By opting to recycle, you will not only reduce the amount of waste in landfills, but you will also enhance workplace safety by retiring your aged batteries.

Don’t Store Batteries For Long Periods Of Time

Lithium-ion products, being rechargeable batteries, are designed to undergo regular charging and discharging. It is generally advised by manufacturers to avoid leaving the batteries unused for extended periods. Therefore, if your batteries have remained untouched for approximately 6 months, it is crucial that your staff inspects and checks them before reintroducing them into rotation. It is recommended that you assess the charge status of the battery before deciding whether to dispose of it or recharge it once again.

Li-ion batteries are renowned for their extended lifespans. However, similar to any battery, their operational capacity is limited, and they will gradually lose efficiency or become completely unusable over prolonged periods.

To preserve the lifespan and effectiveness of your battery, it is advisable to schedule routine inspections to monitor the charge status and establish a regular cycle of charging and discharging. This practice will contribute to maintaining your battery in optimal working condition and ensuring its peak performance.
