Just to add to this - I have done a little research on
what is available in the UK
OEM G1 Battery is – Panasonic DMW-BLB13
E – 7.2v – 1250mAh - 9.0Wh – Li-ion – Made in China –
notice the E on the end of the reference
PRICES
OEM replacements seem to range from £55 to £100 - some with, ........ some without the
E
after market range from £14 to £30 – and most are marked 1300mAh, (not 1250 as the OEM one is), - I have not seen any with the E - all I have seen are marked 13 NOT 13E
All are made in China
Question: Maybe most of the aftermarket ones DO NOT work with Firmware version 1.2 and above – some vendors clearly state that their batteries ONLY work with firmware 1.1 or earlier
Can anyone comment – is the E to do with firmware 1.2 upgrade
Does anyone know the difference?
Amazon list a few
The battery sites on the web have them
The crafty ads do not let you see the spec side of the Battery
If you look at the comments
here
which I do not quite understand in relative to what they are selling, it seems to state what has happened
