Battery change on a Brita Elemaris water jug filter

Fri, Apr 24, 2015 2-minute read

I own the Brita Elemaris water jug. Very happy with it as it’s slimline and fits neatly in the fridge. Could be a bit bigger, but hey, couldn’t most things.

The mini LCD readout on the top is pretty useful for knowing when to change the filter. I actually run it through twice, but nevertheless it’s good to know when it’s time to change. The readout is supposed to last 5 years and is not user serviceable. Well, I’m sad to report that it won’t last 5 years but fortunately it is is user serviceable. I’m sure they only tell you it’s not serviceable to get you to buy a new one, and although the jug is pretty cheap nowadays, I didn’t feel like splashing out £15 to replace a £2 battery.

It’s remarkably easy to do. You’ll need:

a) A couple of small flathead screwdrivers (the type you might find in a computer repair toolkit)
b) A CR2032 battery

  1. Pop the readout unit (with the white stalk) out of the jug lid
  2. Around three sides of the clear plastic unit, you’ll see tabs. One end doesn’t have tabs. Using the flathead screwdriver, gently pop the clear plastic up
  3. When you’ve done all three sides, gently release the whole bit from the far end
  4. Using both screwdrivers, release the little PCB from the holder
  5. Gently release the battery cage from the PCB
  6. Swap the battery
  7. Follow the steps in reverse to put it back together

Job done. Press and hold the reset button and all should be right again.
