Which battery must I buy for prs-500 replacement?
After 2year, battery time is shorter than before.
I am planning to replace my battery to new one.
When I read the previous articles, there are no specific information for battery model number.
I just found these.
Are these ok for prs-500?
Is it possible to replace with bigger capacity?
If you already tried some battery, please tell me model number or link.

Do you have the physical dimensions of the old cell? The physical fit should be the only issue. I assume those Powerizer cells have protection circuits on them -- they look like it and they wouldn't be able to sell them retail without them. I'm sorry, I don't have the dimensions of the standard battery. You could take it apart and measure it, and then find a replacement that was the same size or smaller. Also note the lead arrangement.
Any capacity should be chargeable, depending on the end-of-charge algorithm. The better battery-charger chips monitor terminal current so they will accurately charge any capacity cell. The not-as-good chips charge for a certain amount of time (usually 3 hours) and then cut off regardless of the current.
If you do increase the capacity and the charge time does not increase somewhat proportionally, just pull it off the charger and then plug it back in for a second session to "top it off" (in case the charger is one of those time-delay charger may not leave enough time for a full charge the first time).
Do not try to install a cell that doesn't fit, and be careful not to puncture the capsule while you're attaching and installing it. Use minimal heat with a low-wattage soldering iron. If you damage the Lithium Ion battery, overheating and fire could result later on with charging or discharging. Do not install a cell if it has damage to the capsule.
Modern LiPoly construction and composition minimizes the risks, but do take care when handling these cells. Dispose of the old one properly at a recycling center or a store that receives LiIon cells for recycling.
You proceed at your own risk. I offer advice without any guarantee or warranty.
I've worked quite a bit with these cells and charging chips so let me know if you have any questions.

A few days ago I found pdf document on the net
"Sony Reader PRS500 Service Manual"
It might come handy when you try to disassemble the Reader.
Just put the above name of document into google, download the six rar files, unpack and of you go ...

Could someone with an Amazon account please go and inform the people on the Amazon Kindle board that you don't have to throw your reader away when you need a new battery So tired of the misinformation about Sony's on there.

What one could do to make battery last longer? I think the battery is good to recharge 1000 times, that's 1000 weeks if recharge weekly, isn't it? Oh, that's like 20 years, I know, too good to be true
