- a Panasonic CR1220 battery, or equivalent.
- a Pozidriv PZ00, or similarly sized, phillips screw driver.
- a bowl
This is where the bowl comes in. You want to unscrew the screws in a dish, or a tray. This is because they are about the same size as a pencil lead tip.
And if you drop them on carpet, you’ll waste time trying to find them. Drop the screws onto a tiled floor, and they’ll bounce and bounce and bounce away.
Gently lever the battery out, and place the new battery in.
Put the screws back in, and you’re done.
