Batteroo testing
<< < (8/127) > >>
EEVblog:
I've started testing a single AAA MP3 player,  a Creative MuVo TX supposed to be 11hours on alkaline.
Forgot to plug headphones in  :palm: Oh well, still a good test. Started the test again with headphones.
All same batch Duracell Ultra's and all batteries are numbered on camera.
Hard to find products around the home and lab with AAA's and a short run time conducive to testing.
Once the Batteriser arrives I'll repeat the test with the Batteriser on a new cell and then slip the currently discharged cell into the Batteriser and see how much longer it runs for.
Have not tested this player for dropout voltage yet.

As I've mentioned in the other thread Dave, you have the world's bestest Batteroo testing equipment, PROBES!

Hmmm but then again I think the sleeves going your way was AAA wasn't it...

Would be real simple and easy to see to test the three condition of:
1) Run Probes on regular batteries until he stops or shows sign of starting to stop (if that makes sense hmmm)
2) The above, with Batteroo in from the start
3) Grab batteries from 1) and shove it up Bob (errrr I mean PROBES') backside

Anyway, waiting with anticipation !

Right, if they use AAA, usually it is for low powered devices like remote controls etc. And testing it with an Apple keyboard could need a few months. Maybe that's the reason they chose this for their promotion video? Joe Sixpack doesn't do methodically side-by-side tests, but just sees the low battery warning and then is happy if it is full again when he puts on the sleeve, even if it might have run longer without the sleeves. Quiescent current would be interesting, too, because this could make Batteroo unusable for low power devices. BTW, the latest Apple "magic" wireless keyboard uses integrated rechargeable batteries, as many other devices nowadays.

A device with a motor would be perfect. I couldn't find a female test person who wants to demonstrate the kind of device on camera Wayne tested last ("really, only for science"  ;D ), but I found another toy, with one AAA battery (Battery Powered Engine):



I glued the tracks with double-sided tape to the pertinax board, for same test conditions for each test (they are a bit loose otherwise and the train can even derail), and will do a test without and with Batteroo on camera with a fresh pack of batteries and with a timer until it stops (already tested it off camera, it does just stop after a few hours).

Yes three AAA's only.
I'll pick up some AAA to AA converters tomorrow from Jaycar

This is exactly how I've setup my product testing spreadsheet.

Bingo. That is what they are counting on. It's up to us engineers to run controlled tests and compile data on a bunch of products to prove what the product actually does.
And at every chance we my point out that the battery gauge in every product is rendered useless.
