Cycling rechargeable batteries, often referred to as reconditioning, involves completely discharging and then fully recharging them to potentially improve their performance and lifespan.
Understanding Battery Cycling
The idea behind cycling is to help "reset" the battery's chemistry, potentially reducing the memory effect (though this is less of an issue with modern battery types like Lithium-ion). This process can sometimes help restore capacity or balance the battery's cells.
Steps to Cycle Rechargeable Batteries
Here's how to cycle rechargeable batteries, based on the reference provided:
-
Discharge Completely: Use the battery in a device until it is fully discharged. This means using it in a device like a camera, toy, or torch until the device no longer functions due to low battery. Note: Avoid forced deep discharge (e.g., short-circuiting) as this can damage the battery.
-
Recharge Fully: Once fully discharged, recharge the battery completely. Use a standard charger and avoid ultra-fast chargers, as they can generate excessive heat that could degrade the battery.
Why Cycle Batteries?
- Recondition Battery: Cycling can sometimes help recondition rechargeable batteries.
- Improve Performance: It can help improve battery performance.
- Extend Lifespan: Cycling might extend the battery lifespan.
Important Considerations:
-
Battery Type: Cycling is more beneficial for older Nickel-Cadmium (NiCd) or Nickel-Metal Hydride (NiMH) batteries that are prone to the memory effect. Modern Lithium-ion (Li-ion) batteries generally don't benefit much from cycling, and excessive cycling can actually reduce their lifespan.
-
Frequency: Don't overdo it. Cycling Li-ion batteries too often can actually reduce their lifespan. A cycle every few months is generally sufficient if you suspect a performance issue.
-
Charger Quality: Always use a high-quality charger designed for the specific battery type. Poor-quality chargers can damage batteries.
-
Heat: Avoid extreme temperatures during both discharge and recharge. Excessive heat can negatively impact battery lifespan.
By following these steps, you can effectively cycle your rechargeable batteries to potentially improve their performance and longevity.
