Operating Instructions
Initial Charging
For optimal performance, it is recommended to fully charge the battery before its first use. Connect your Aiwa device with the newly installed BORNMIO battery to its original or a compatible charger. The charging indicator on your device will typically show when charging is in progress and when it is complete.
Regular Use and Charging
Charge the battery whenever your device indicates a low power level. Ni-MH batteries do not suffer from a significant "memory effect" like older battery types, but occasional full discharge and recharge cycles can help maintain capacity over time. Avoid completely draining the battery repeatedly, as this can shorten its lifespan.
Maintenance and Care
- Storage: If storing the battery for an extended period, charge it to approximately 50% capacity and store it in a cool, dry place away from direct sunlight. Recharge it every 3-6 months to prevent deep discharge.
- Cleaning: Keep the battery terminals clean and dry. Use a soft, dry cloth to wipe away any dust or debris.
- Temperature: Avoid exposing the battery to extreme temperatures, both hot and cold, as this can degrade performance and lifespan.
- Disposal: Do not dispose of the battery with household waste. Consult your local waste management facility for proper recycling or disposal options for Ni-MH batteries.
