Anywhere MX and Eneloops

Anybody here use Eneloops in their Anywhere MX? If so, how much battery life do you get per charge with 1 and 2 batteries?

Mine barely last 3 weeks per charge

 

mine lasted 3 months with 4 hours of on-off use per day, 5 days/week. you sure they were fully charged when you put them in?

 

My batteries definitely didn't last three months in the Anywhere MX. Probably more like 1.5 months, and those were non-rechargeable heavy-duty AA batteries. Are you turning your mouse off when you're not using it?

 

I can't say for sure with the first pair of batteries, but with the second pair I deliberately drained 2 batteries by sticking them into my digital camera and going click-click-click with the flash on until the batteries were completely drained (I actually filled my SD card and had to delete photos and start again before the batteries died ), after which I recharged the batteries overnight and put them into my mouse the next day.

I'm not turning the mouse off. Does it make a big difference if I do?

 

Not sure; the Anywhere MX seems to go into standby faster than the Performance MX I have right now, but I think it does make a difference. If you won't be using the computer for the night or are getting lunch, etc, you should probably switch it off though.

 

Mine barely lasts a month...

If you don't switch the mouse off, it stays in standby. The laser is turned off, but the sensor is still on. Your battery life should be greatly increased by switching the mouse off when not in use.

Also, eneloop is just Sanyo's brand name for their rechargeable batteries. What are the specs of the batteries you are using, how old are they, and how much have you used them?

Either way, in such low-load environments such as a mouse like the Anywhere MX, non-rechargeable AA batteries would generally last longer than rechargeables.

 

I asked about Eneloops because (aside from the fact that they're what I'm actually using in this mouse) as the first low self-discharge NiMH batteries to hit the market and the ones that popularized the concept, they've become kind of an umbrella term for the entire category of low self-discharge rechargable batteries. If anybody's using Duraloops, Rayovac Hybrids, Tenergy Centuras, etc., I'd be happy to hear about their experiences too.

Low-load environments shouldn't be a problem given the short durations we're talking about here. Sanyo claims Eneloops should retain 75% of their charge after 3 years sitting in storage, and real world tests done by extremely patient people have confirmed that those claims are reasonably accurate. Personally, I've had the same Eneloop in my quartz clock for over 18 months now, and it's still going strong.

 

Eneloop is any rechargeable battery made by Sanyo, so that really gives us zero information on the actual batteries you are using. They make / have made more than one AA battery, and age and use also plays a role. So you could expect really low battery life using old, heavily used, low-capacity cells, or you could expect months out of new high capacity cells.

What I mean is that with different loads, the usable capacities of batteries change, so you can't rely on the mAh rating to directly compare.

 

There's only 3 Eneloops - the first generation, the second generation, and the third generation. FWIW, these are second generation batteries that are about a year old, but AFAIK all 3 generations perform similarly and big differences are largely in areas like the total number of charge/discharge cycles, how many years they can hold a charge for, and whether they're pre-charged by fossil fuels or solar power, none of which significantly impact the discharge rate in a mouse.

There's also Eneloop XX batteries, but if I was using those, I would've said so explicitly.

I don't get what you mean. Everyone posting on this thread should be using their batteries in an Anywhere MX mouse.

 

Mine last 3 month or so... but this is due to me ONLY using it when I work, which is only at school or when I need to do some homework/business related things

 

My co-worker uses an Anywhere, he said he charges his only once a month. Pretty amazing ask me, I charge my MX Performance every 2 days, but no matter since can just keep using it while charging. But a month, that's awesome. Though he does say, my Performance MX response and performance is noticeably better than his. Oh well.

 

I use Duracell Procells in mine and I get about a month of usage before they start giving erratic movement or just outright dying, but I don't turn the mouse off unless I remember to (maybe once a week?)

Rechargeable batteries tend to not work well in mice that use AA batteries because most are designed to run off 1.5v, not the 1.2v that rechargable NiMH does.

 

its not the batteries that are the problem, its the darkfield sensor that really uses a lot of power.
compared to my old nano vx mouse which could last for three months of average use on two smaller aaa batteries, the anywhere mx lasts half as long.
of course you could go for non rechareable batteries, and you would get a bit more usage; but for such a power hungry mouse, i dont think thats really adviseable

 

like I said earlier in the thread. I got 3 months, but I also turned it off whenever i walked away from my comp (too easy for people to start ing around with my mouse and mess up my workspace - most people aren't aware of the power switch) and i DEFINITELY did not leave it on during meal breaks.

that is ridiculously poor performance. are you literally moving it for 48 hours in a row? mine lasts roughly 6 weeks (being very conservative here - i've only had to recharge it twice that i recall)
