Battery Replacement

Can anyone measure the voltage of the battery with a simple voltimeter-tester? DC.

Look for the battery that is mentioned here (US473850A8T) and is sold like 3.7 volts.

It is possible that it accepts voltages from 3.7 - 5.2 for charge , or the Sony has an internal stabilizer IC to reduce the voltage from the charger (5.2 volts).

All pages to buy this battery are in chinese with register.


Here Sony Li-Polymer [ 3.7V ] batteries :

I think is only to drop the yellow tape from PRS battery and sold 2 wires (red-black) with conector from old to new battery.

But the problem is to identify the correct model of battery and buy it in chinese.


Battery from PRS-505 may be not equal to the PRS-500 as I see in this photos :

I can read only US32xxxxxxH

And I cannot find none battery with similar reference.

Although may be the same as 500 with another manufacturer , ru ?

Measures from 500 are : (50mm x 37mm x 4.7mm)

Here batteries from sony clie 3.7 volts looks similar:

Why not open your 505 and have a go at a volt meter and see what the battery is like?

Then why do you plan on purchasing a replacement battery even before you got the reader?
Its battery is fairly good and will last 1 year at least (it should last longer of course).
Also before you buy a replacement I would recommend to get the reader and have a look at it and then decide whether you are good enough to replace the battery because the reader was not designed to have a replaceable battery, it means to replace it is not a trivial process.
