dm-15cc battery life
Message #1 Posted by David Griffith on 27 Nov 2012, 1:56 a.m.

Does anyone have any figures on the battery life of the dm-15cc? I have one from the first run that I last played with maybe in March. Today I pulled it out and found the battery apparently dead. I'm not sure if it is dead or something else happened because my multitester is nowhere to be found.

Adding a capacitor might fix this:

Hi David,

I have a DM-15CC of second batch. I measured its current draw after updating the firmware to DM15CC_MEM1B_V10.
I hope this helps you.

Regards,
Lyuka

Lyuka, can you do the same for the 20b/30 (original firmware) as well as the WP 34S firmware? I'd like to see how well I did my power saving job.

Hi Marcus,

Yes, I'd like to do that when I got a 20b/30.
There must has come the time to start using the WP 34S to me ;-)
