Review: Book Digital Co. SmartBook G138 (Flashback)

What cells does the Smartbook normally come with? 2200 or 2000? If i put new batteries in will they need to be calibrated somehow? 1960 seems a bit low, so i'm not sure if i should do it yet.

I believe C:amie offered you a superb deal on a new cells - suggest you take advantage of that if you can.

Trouble is C:Amie appeared to be in a bit of a hurry, and i have no money for the time being. If the offer is still available C:Amie would you accept cash via post?

mine came with two Samsung IRC 18650, one 2200 and the other 2000. they are marked Samsung SDI
IRC 18650-22,IRC 18650-20.

S/F,
CEYA!

no need to reprogram battery.

but if it indeed comes with a 2000 and a 2200 mAh cell..... well, dont expect it to last long! crazy!!

Cmonex, It did indeed come like that or I wouldn't have said it.

Maybe that is what is happening to his G138.

chazco,
Did you take the plastic off yet?

Not yet... possibly later.

I'm having trouble searching the forum... can anyone explain (pictures even better) how you open a Jornada battery (the 728 one). I'm going to put the cells from that into it.

Weird how your device has a mix and match in it. You certainly wont be getting the benefit of the 2200 one
Chazco's has two Samsung ICR18650-22's in it.

Unfortuantely when Chazco approached me re new cells, I had already sent the order through and it was too late to ammend. I will however make him the priority if I have and spare after my various projects.

To get into a Jornada battery, effectively you have a vacuum moulded casing sealed around two cells and a charge circuit. the charge circuit is in the extrusion region where the pins are. The only way you can get into it is with a sharp stanley knife and a LOT of very careful cutting. Scratch up the charge circuit and it'll never work again and impact the cell significantly with a sharp steel blade and bad time will be had by all.

I think i'll leave it then... sounds too risky. (just found the video of the exploding Dell laptop)

If C:Amie can spare some cells then i'll send the pack to him. If not i'll probably HPC:Bay it (its no use without power)

btw... its now down to just 43%

Just thought i'd post this in case its any use:

GPRS Speed Test Results
I found a PAYG solution that offers unlimited GPRS in the UK (works out at £30 a month, but can be turned on/off on a daily basis), and i've taken the chance to run some of the speed test pages (normally expensive over GPRS) to see how the G138 handles it.

Note: All tests were on mains power and performed around mid-day.

From a suburban location, on a stationary surface:
Maximum Speed: 82Kbps
Average Speed: 49Kbps

From a rural location, on a stationary surface:
Maximum Speed: 52Kbps
Average Speed: 27Kbps

From a moving vehicle (powered by an inverter), held roughly level:
Maximum Speed: 32Kbps
Average Speed: 12Kbps

Those speeds would seem to be GPRS 8 speeds, which is quite good.

I'd really like to be able to use this speed, so am hoping C:Amie will have some spare cells. If not i'll try to find some and see if he can fit them

Whatever happens Chazco, I'll make up the new battery for you, no charge. Don't worry there

The GPRS information is very interesting, thanks for taking the time to test and to post. I guess you're really free now

Thanks, was hoping for that


No problem

I was working on getting you some batteries.


S/F,
CEYA!

I've been looking at cells but will wait until C:Amie knows for certain

Any idea when you'll know if you have some spare cells C:Amie?
