Solved How long an (Energizer's) AAA battery can last?

Hey guys, long time no see eh? :)

So I'm using a wireless mouse with my old laptop (but other than the RJ45 port and internal wireless adapter, the laptop is still good), but recently the mouse was moving (kind of "dancing") on its own. When it's not moving, it just feels "hard/heavy" to actually move the cursor/pointer.

So I changed the battery (from Sony's to Energizer's) and all seem good so far, but I wonder:

1. What could be the problem, since the old battery - as stated by the mouse seller - was brand new. Or was it not actually new? Is there a way I can find that out? I bought the mouse+battery on Jan 6th 2020.

2. How long does an AAA battery last? 3 months? 6 months?

And should I turn off the mouse whenever the laptop screen goes off? I mean, turn the power off - the mouse itself becomes inactive after a few minutes (I think?).

Batteries when removed and left a wee while can occasionally recover a little capacity - which soon is expended when reinserted and used in whatever... This was often the case with old style zinc batteries; and even with some of the early alkalines.

But that extra life was invariably very short.

Personally my approach is that if a battery has had a long period of use - and the device is showing problems... then wiser to replace battery as starting point. If problems persist, then it "may" not be the battery.

I have Logitech bluetooth rodent Mac (and possibly some windows) compatible - but not win-7!!! Occasionally it starts erratic behaviour and replacing the battery sometimes resolves - and sometimes not. Even a full power down/up (full reboot) doesn't always resolve the problem. Leave Mac powered down (switched off) for a while and the problem doesn't reappear...

There are some issues with bluetooth that can result in intermittent problems with devices various. The early blue tooth uses the same frequency as quite a lot of other kit - wifi devices... It may be that the rodent's erratic behaviour may be suffering from interference. As I understand things more recent versions of bluetooth don't suffer from this problem.

Your rodent is also a bluetooth device - how olde, what make/model?

Leakproof batteries are not worth storing once they start to lose power (as you suggest to do). Leakproof batteries "do" leak; be they in effect off the shelf varieties which are not rechargeable, or even rechargeables of a decent age. I have found more than a few (premium brands included) off the shelf non-rechargeable which have leaked whilst left in-situ and the equipment not used...; and one or two rechageables too.

How long can/will a AAA last? Depends a lot on where and how they were stored prior to your purchase...; and also if they're the genuine article...? Not uncommon to find best by dates way off the mark - be it AA, AAA, C, D, and the whole range of mini batterie... Frequently hearing aid batteries vary in terms of life - even though all showing the same best by date...

Button/disk batteries (whatever type) likewise; but not as often in my own limited experience.

Batteries have a pretty good shelf life in general. How long they last in a mouse depends upon the mouse - some will eat them up in a couple of months, some will last a year or so. I always use rechargeable ones.

Sorry, I spoke too soon... 🙊✌ and thanks a lot, I'll consider buying a rechargeable one. 🙂

But for now, I'm just worried that the "moving mouse cursor/point" may happen again - with the new battery.

So if anyone has any thoughts, please do let me know!

Generally an alkaline battery will last longer than a 'heavy duty' battery and a lithium will last longer than an alkaline. My guess is the original battery was some low-quality junker. Most will have a 'best if used by' date on the battery. You may just need to see how long the energizer lasts and then decide what's best. I wouldn't think that turning it off for short periods of time would make much difference but for longer periods--and when the laptop is off--it's probably a good idea to turn the mouse off.

So I checked. The Sony battery's expiry is June 2023, while the Energizer's is Dec 2029.

So what's up with the Sony battery?

Why would it suddenly made the mouse cursor jumping? It can't be that the laptop is picky, no?

If you insert the old battery, does it still jump? Maybe the battery change just resets the mouse circuitry.

I had a few "rechargeable" mice and the internal battery went dead after a few months.
The one I use now (plain Logitech not even a year old) starts to have problems with the mouse buttons; 1 click act as 2 clicks or double click.... I'm looking for a reliable PC mouse but I wonder if that still exists....

If you saw some of the junk batteries that China puts out, it'd pretty well p*ss you off. In a former job I had we would get stuff from them that was "labeled" as Energizer Alkaline batteries with 2019 expiry dates (this was in 2014), and they'd already started to leak.

Hey guys, thanks to @sluc, but before he posted his message, I tried swapping the Energizer battery with the Sony's and the "moving" issue is no longer there!

So I guess the laptop/system was just running out of memory/resources causing the mouse sensor (or whatever is the right term) to not work properly...?

Because back then, as far as I could remember, the laptop had been "on" (never turned off, only went to sleep and sometimes hibernation) for many days... or maybe 1 or 2 weeks.... and there were many Chrome tabs opened, too.. Well, like 12 to 15 in one window, plus some in another window..

Silly me, I should've just tried restarting the laptop! 😀

But then, is that "moving" mouse cursor a normal thing when the system is running out of memory/resources?? Or is it just my laptop? 🤔

And if I may ask further, would it be safe if I just put the other battery somewhere and use it later? Or do I need to store the battery in a specific place?

I mean, on that day the issue started, I later had to force shut down of the laptop (by long-pressing the power button), but I was already using a wired mouse and didn't think of trying again with the "old"/Sony battery.. until today... 😅

Any thoughts on the last two paragraphs in my previous reply?

Thanks everyone. 😘😊

But apparently, there's something not right with the Sony battery or maybe my laptop/mouse just doesn't like that battery after lots of mouse "movement" or after a prolonged use, because the issue occurred again and I'm just going to using the Energizer battery.

Btw, my laptop's trackpad has actually been long not functioning (at all), so I don't know if that may have contributed to the issue.

Cheers!
