I've modified and repaired a lot of batteries before, never had any problems. The one time out of dozens of modifications I had problems the battery got super hot and I pulled it before it caught on fire.
Yeah so 2.2 ah = 2200 mah. The standard oqo battery pack is 4500 mah. That's crazy that a huge ass lead acid battery is less mah than a tiny lithium ion laptop battery. Hmm
So I guess I'll go with the battery packs. 2 of these are what is in a standard oqo pack.

So 12 volts per hour is 3 times higher than the lith ions. So it would if I could hook it up directly last 3 times as long. Probably even with the conversion through the power supply my guess is that it might still last 2 times as long which would be like 5 or 6 hours.
I trained as an aircraft and power supply technician. We learned all about batteries, how to recondition them and such. The only thing I'm shaky on is how the recharging circuits in laptops, and specifically the oqo works, and how it senses how much capacity a battery has. I'm not sure that it matters. I've repaired batteries on pda's before and put in larger capacity batteries and at least in those pdas the recharging circuit didn't seem to notice.
I know there are double capacity batteries for instance for the oqo that do exactly what I want to do, they just stack 4 cells instead of 2 into the battery, but the question is if it's a different pcb running those batteries.
