Bad news --- should not go below 9.5 in any case while cranking Quote:
Ok, I do have battery issue. Yesterday it had shown 12.6V, what happened now?

answer is ' surface charge ', connect multimeter , put on headlights for say 15 seconds --- check again . Must show 12.5 at least ( fully charged battery ) Quote:
Sachin suggested driving it around for 30 minutes.

Not recommended ,these things don't work when the battery is so low Quote:
But electrician wondered whether we can use the charging device from the office generator which charges the 100AH battery. But he also wondered whether the 100AH charger will damage the 90AH battery.

dont see a problem here , check the charging voltage & current Quote:
Now, we have connected the charger to the Jeep battery and hopefully it should fully charge in an hour.

dont think so ( wrt full charge ) I would do it for at least 6 hrs Quote:

next time you start check the voltage for 10 minutes at engine mid speed
check following with multi meter
1) Voltage of battery before & after surface charge ( a good battery > after surface charge gone 12 minimum )
2) voltage at cranking ( 9.5 )
3) voltage just after engine starts & then for another 10 minutes ( 12.5 minimum & 14.5 max )
Important : take off the negative wire on battery & check if any wire is not loose wrt alternater
