@Robertb,
Yes it does seem a bit erratic at best the battery gage, After doing the battery disconnect charge I got about 750 odd page turns and still had a fully battery, I then charged using usb with out battery disconnect and only got 435 page turns before the battery showed one bar less. It does seem strange that some ppl can go 2000 odd page turns and still show full charge

. I am going to buy another battery off you just to have as a spare and also to see if I get more millage out of it

Thanks for your input Robertb
