1. Cut the ball into 2 halves with a knife. 2. Connect the battery, switch and the buzzer. Battery and buzzer should have terminals â€“ advantageous and poor. Make certain to attach the matching terminals. Now to the one wire connect the switch. 3. Place both the battery and buzzer together with the connected cord within the ball.
Every lead-acid battery is provided with datasheet for standard charge current and discharges current. Typically a 12V lead-acid battery which is applicable for the automotive application could be ranged from 100Ah to 350Ah. This rating is defined as the discharge rating with an 8 hour timing period.
