| + | [title] Test the compatibility of the new battery |
|---|---|
| + | [* black] To make sure that the battery will not be damaged by the recharging of the lamp measure the new battery voltage and the voltage delivered when the crank is spinned. |
| + | [* black] Attach a capacitor to the terminals of the old battery. Mount the gears and the crank. After spinning the crank a few times measure the voltage of the capacitor with a multimeter. |
| + | [* black] Measure the voltage supplied by the new battery or read the datasheet of the battery. This voltage should be roughly the same as delivered by the crank. |
