Q2: What is the difference between a backpack battery and a standard plug-in battery? (What is the difference between a backpack battery and a standard plug-in battery?)
> A: Backpack batteries offer significantly larger capacity for extended runtime and are worn on the back to reduce arm weight, ideal for long working sessions.
> *(Backpack batteries have a larger capacity, providing extended battery life, and through the backpack design, they reduce the weight on the arms, making them very suitable for long-duration, high-intensity work.)*

Q3: How should I store the battery when not in use? (How should the battery be stored when not in use?)
> A: We recommend storing the battery in a cool, dry place and keeping it charged at around 50% if not used for a long period to prolong its lifespan.
