The search has begun , for a true 3000mAh battery :
Two batteries arr better than one !
1, Ultracell 3000 , was first charged then discharged at 500mAh resulting in 698mAh capacity , a disappointing and fraudulent 2302mAh short of the advertised mark
2, GooP 3000 , charged + discharged at 500mAh resulting in 734mAh capacity , a disapointing and fraudulent 2266mAh short of the advertised mark
Well , it would appear that anyone buying either of these batteries are going to be defrauded by a whopping 75% + on the promised 3000mAh capacity .
Obviously neither battery is the Grail of AA batteries! so the search will continue .
i’ve got some, and that capacity is nearly accurate at 500ma discharge (>2500) but they cheated - they’re the biggest AAs i’ve ever seen and won’t fit in some things
Well , a few Dollars to prove one way or another - some are prepared to do this others not .
As for the epic fail - its not about anything but putting the proof out there ! Evidence / fact / truth ! something sorely missing in the world .
So its a community service [ flashlight community ] .
I think those two batteries cost all of $2.50 , so now if some one does a search , they may find the true capacity of these batteries and move on the the next rip . [ such is life ]
And I think I have mentioned this battery crap to Ebay , but ? Probably to much $ involved for the truth to get in the way .
So perhaps this means this thread is concluded, if a mainstream manufacturer pushing the envelop has to make the batteries almost too big to fit the appliances, then 3000 mAh is not doable yet.
I will be looking forward to you results. Ive used plenty of there 2200mAh with no issues at all except with three kids I dont have any left. I will have to stash these ones.
I have some Sanyo Harmolattice batteries that were just over (and under) 2500mAh. I don’t recall if I ever did a break in cycle on them though.
I made a webform you input the batteries and values and it pops out on the spreadsheet, I was going to make it public for everyone here to put their results too but I kind of lost interest.
I'll be interested in seeing your results for the Sanyo 2700. After a couple years, I have nothing good to say about them except that I think the wrapper looks rather snazzy.
When this thread was started i thought there might be such a battery out there, but by the time of the post you quoted i realized that there is little chance of it currently. If a real manufacturer has claimed such a capacity and your testing their batteries, then i will revise my opinion to may possibly exist.
I do hope someday there is 3000 mAH and more, NiMH has a better lifetime then Lithium.
