To ensure optimal performance and longevity for your BC-4S replacement battery, follow these key charging practices:

Avoid letting the battery become fully drained before recharging, as exhaustive discharge can significantly shorten its lifespan. Instead, it's recommended to connect your device to power when the battery level drops below 20%. Furthermore, always charge the battery in a dry environment. Crucially, pay close attention to temperature, especially avoiding high heat during charging, as this is the single biggest threat to your battery's long-term health. By charging proactively and keeping it cool and dry, you can maximize the life of your BC-4S battery.

For Optimal Long-Term Storage of Your BC-4S Keyboard Battery:

If your BC-4S battery will be unused for an extended period, follow these steps to preserve its health and longevity:

1. Prepare the Charge Level: Before storing, ensure the battery is charged or discharged to approximately 40% capacity.

2. Choose the Right Environment: Place the battery in a dry and cool location.

3. Mind the Temperature: The ideal storage temperature range is between 15°C and 25°C (59°F and 77°F). Temperatures outside this range, whether too high or too low, can significantly accelerate battery aging.

4. Perform Monthly Maintenance: To maintain the battery's health during storage, fully charge and then fully discharge it at least once every month.

5. Return to Storage: After each monthly cycle, recharge or discharge the battery back to around 40% before returning it to its cool, dry storage place.

Adhering to these storage guidelines will help maximize your BC-4S battery's lifespan and performance when you need it again.
