The adapter is designed to cope with 1 amp, and not a load 2 1/2 times that, so the short answer is 'no'. Likely to generate a lot of heat, might work for a while but personally I wouldn't risk it...

no, voltage of your adapter will drop due to excessive load, and it will harm your adapter.

(from title i thought that you want to use a 12v lead acid battery instead of 12v rail of psu to power your rig)
