How to change the battery in your Clever Logger

Before you begin, you will need:

1. A flat blade

2. A new CR2450 battery
(available from supermarkets etc)

3. A small Phillips head screwdriver

Or just order a replacement here…

Step 1. Buy a new battery

You need a new CR2450 which are readily available from supermarkets and hardware stores…

…or simply order

a replacement here

Step 2. Remove the sticker

Use a flat blade to lift up a corner of the sticker.

Peel it off and set it aside carefully, sticky side up, so that it can be re-used.

Step 3. Remove the four screws

Use a small Phillips head screwdriver to remove the four screws.

Put the screws in a safe place.

Once the four screws are removed, you can open the casing. You may need to use your flat blade to separate the two halves.

Step 4 Remove circuit board

Carefully take out the circuit board. Try not to touch any components.

Step 5. Replace the battery

Slide the old battery out of the slot. It may help to carefully push it from the other side with the screwdriver.

Pay attention to which way up it should be.

Dispose of the old battery thoughtfully.

Pop the new battery into the slot.

Step 6. Replace circuit board

Place the board back into the casing.

It only goes in one way. Do not force it.

Step 7. Close the casing

Close the casing and replace the screws.

Step 8. Replace the sticker

If the sticker is damaged, call us and we can send you a replacement.

(There is an extra label included in the replacement battery kit.)
