SR41.....
so 4.5V, 25-32 mAh. it won't last 20 seconds before it dead reckons to dim mode.
but I want one! XD
Testing with fresh batteries, it went from 75mA to 50 mA during the 2 mins. Of continous test. After that, it was dropping with a quicker rate. I've been using the prototype since June, with shorter bursts...but it still lights up quite well. What do you base your estimates on, if you don't mnd me asking? By the way, they are 1.55V each, so it would be 4.65 Volts. I'm basing this data on tests I've ran yesterday with Maxell SR41W high drain batteries. There are other SR41W equivalents, and I have tried 4 different kind, including Varta, Renata, Energizer....none of them had the performance of this specific one....this is the priciest though, but at least, it's pricey for a reason. If you buy one, you can test it out yourself!
