| I used 18650's with tabs (http://www.batteryjunction.com/tenergy-18650-tab-2600.html). I'll check when I get home. |

| Either will work, you just need the ones with the highest capacity. The 18 is 18mm diameter of the cell. You cannot exceed that and still fit within the casing. The 650 is the length of cell in mm. Shorter will work, just means you need more wire to connect them. But shorter also usually equates to less storage capacity. |

| sorry yeah my mistake... been a while... 18500's were sig3.
18650 is the correct size |

| On batteryjunction there are also 18650 with pcb protection. Do I need this circuit or it is already integrated in the pack of my MBP 900c?
On Rich Hawley site's I have not found process to rebuild battery pack of MBP. Is there another link? |

|
| IIRC without pcb protection as the protection circuit will be in the circuit board in the unit.
John
PS protection of running them too low could end up with the 900c just powering with no warning. |

| Battery pack rebuilded. Now it's testing time but everything seems to be all right in fact with the old battery I would have had already 80% of charge after 2 minutes of web surf instead I am still at 100%. I'll let you know. |

I am good for about 2+ hours of constant surfing using my extended battery fully charged.
sh.t 
on extended, i.e the 4400mAh one?
with 2200mAh original (good condition ) I get 3 hrs on wifi, but my wifi is a nice cf wifi and brightness is like 20-30% usually.
PS: email coming your way soon  |

If anyone has the marvell chipset CF wi-fi card (the 11g one that worked on Sig3) could they try that in a PCMCIA converter.
I found the marvell 11g made a considerable increase in the wi-fi browsing time. IIRC almost an extra 45min +
Just interested to know if that is the same on 900C
i have not tested marvell on 900c...
my cf wifi on 900c (in pcmcia slot with adapter ) is senao sl2511  (just got a brand new one recently, wowo! )
as for original survey: 2200mAh good condition batteries: 2.5-3 hr wifi, 4 without, and on hpc2000 add 1 hour due to lower backlight.
4400mAh a bit better than double these times.
I have about 20-30 2200's and quite a few 4400's (about 8? ), i'm sure some of them are not this good. |

| Well, I have bought two 2200 mAh (these are the only one i have found here where I live). should they give me 2-3 hours of web surfing I will be satisfied.
I could have bought from batteryjunction and they have with bigger mAh but not well know brand so I decided to take lower mAh but branded Samsung. Price in the end would have been the same due to shipping cost.

| Well,
it seems to work great. I have done a good job. Now battery duration it is very acceptable.
Does anyone know where can I get extended cells for packe rebulding? BatteryJunction seems to have available.
Anyway, thanks for help given. |
