Re: Ultimate AA battery shoot out
If you're doing multiple tests why not use an accepted, STANDARDIZED methodology for one of those tests?
It's fine and even desirable to do other tests but it's irresponsible and dishonest to claim cells do or do not make their rated capacities, as you have done in other threads, based upon a methodology of your own creation when the factory rated capacities are based upon an accepted STANDARD which is in use industry wide.
Who is charging at 5A? Why?
Again, your posts are misleading using the term 'real' since you aren't using the 'real' standard for battery capacity measurement.
Real: 'You keep using that word; I do not think it means what you think it means.'
cause i prefer to use more heavy tests, that can help more who do a heavy use of batteries, like us of CPF that load batts at 4-5A, use several batts in series, use fast chargers etc. my test will se also how batts will degrade with different uses, like charge at 5A instead of 1.5A, overdischarge vs. partial discharge, discharge at 4A instead of 1A or 400mA
first comments after few charges:
ansmann 2850: arrived discharged, aren't real 2850 but around 2400-2500 at 1A of load, they can't handle 4A of load with decent voltage drop
ansmann max-e: arrived charged around 77% of capacity, are real 2000mAh and take quite well 4A of discharge
delkin ready to use: arrived at 25% of capacity, are only in the 1400-1500 range of capacity, 3 of 4 handle quite well 4A of discharge while one suffer much more
