Wireless mouse WM126 draining battery too fast!

Hi all,

I have a Dell WM126 wireless mouse with 1 AA battery. I use it every working day in combination with a Dell docking station and Dell laptop. I turn the mouse off during nights/weekends, but still I have to replace the battery every 1-2 months! This is not normal right??!
My colleague has exactly the same hardware setup and she has been using the same battery for 12 months! 

What is wrong with my mouse, and does this problem fall under warranty?

Apparently the warranty period has passed. Although I've had this problem from the very start, so within the warranty period, it's my fault to only contact you now. Is there anything I can do to extend the battery lifespan?

I'm also getting the same issue.

I purchased the mouse on 13 Feb 2020 and currently, this is the third battery I'm using.

When my first battery which comes inbuilt, drained off within the first month, I thought maybe the batteries were old.

Then I added a long-lasting Duracell battery, even that drained off today within 40-45 days.

Earlier I had a Lenovo Mouse whose battery use to last for more than 8 months for the same usage.

I still had a valid warranty but can't go out as everything is closed due to Covid19 lockdown.

Fortunately, I had a spare battery, which I'm using right now.

If this issue continues, I guess I will be spending more on batteries than the mouse price itself in the next 1 year.

Was there any solution to the issue, i have been facing this issue since the time i have bought the mouse. The battery drains within couple of weeks. I use it only for 8 hours and turn the mouse off after use. more over i have tried to check the warranty of my mouse but the 18 digits SN number starts with CN doesn't exist in the support website.

I have also the same issue. I have purchased it through amazon. I have also informed it to merchant but as the lockdown was going on I am not able to give it back to merchant and now the warranty is over. I am facing this issue from begining.

I am facing same issue with my WM118 wireless mouse. It is consuming one battery per week. fed up with replacing battery. Please help!

I have also bought a Dell WM126 mouse last year from amazon and I have changed dozens of batteries till now. I generally use Duracell batteries, they are well known for lasting longer. Is there any way for resolving this high battery drainage issue or I should buy a better mouse?
