Replacing CR1620 lithium battery for Ultramax OB24

For consumers with the Brita Ultramax (OB24), the one with a digital memo. Here's how you can modify the battery housing for replacement.

Important: It is best to take pictures along the way so you know where the parts go during re-assembly.

I attached photos along on bottom of page for easy viewing.

1.) Remove the battery housing unit from the cover. It is easier if you unclip the small cover off from the larger (main) cover to do this. Carefully pry along the edges with a butter knife until the housing is raised up enough for you to pull if off with your fingers.

2.) Turn the housing upside-down (LCD reader faced down). Now carefully cut/slicing along the topside outer edges of the battery unit with a razor blade. Make sure it is cut evenly so that it can be reused as a 'cover'.

3.) After it is cut and exposed, tap the internals out of the clear plastic housing so you can get access to the battery. Stick something thin (such as the newly cut plastic cover) through the battery lever and push the CR1620 battery out. Replace battery, put everything back into its plastic housing.

4. After everything is reassembled with its new battery, put the (cut) plastic cover piece back, hold gently and wrap some clear packing tape such as 3M. You'll have to measure the tapes and cut them to fit. Secure the top portions with tape, then wrap along the sides to secure the rests.

how can i separate the two parts of the reservoir to wash it without breaking it?

I just figured out how to separate the two parts of the Brita Ultramax water reservoir so they can be cleaned!!!
Empty the Brita of water. Whatever water is not removed through the spigot will drain out if you turn the filter upside down. Then let the two parts air dry for an hour or so. Now hold the two parts between the thumbs and middle fingers on each end, press your middle fingers against your thumbs. Then slide your middle fingers up, and the white part lifts out of the clear bottom! Yay!! Now the clear reservoir can be CLEANED!!
