Thanks for the feedback and link. I did a bit more research and found an article on wiki (
Lithium-ion battery - Wikipedia, the free encyclopedia) that explained some things for me. It's fairly tech-y, but has good info about the aging characteristics of Li-Ion batteries.
Since I bought this in China (with a friend who speaks Mandarin), I know it is truly a 2GB MP5. What I don't know is how long they had it in their stock. If it was there for over a year, then the battery already lost 20% of capacity, maybe more. Now, 2 years hence, and capacity has prob'ly dropped to 50% or less. Prob'ly time for a new battery anyway (saw the same thing happen with my cell phone
I have an electronics background, so I can prob'ly use a battery with contact points (instead of wires) and solder (carefully!!) to the contacts.
In my unit, length and width aren't critical. However, thickness is. Prob'ly some margin, but not much.
After thinking more about the battery, my belief is that it does say 3.7V on the 2nd line (before the 520mAh). It looks like the "3." never got printed. This area is located right below the "XX" I couldn't read (mentioned in my previous posting), and I can see how the "3." could have been left off.
Thanks again for the help....Steph
