Samsung 1200 mobile shows charging paused for battery durabiity, when i connect with charger

SOURCE: my phone wont charge

check your charger first, if charger is ok then check the charging connector on the phone, clean it with a toothbrush and solvent cleaners.

First clean the charging port.

SOURCE: charging

i think the solution to this problem is to let your cellphone go dead
my friend told me today that my d900i was overcharged so thats why it wouldnt charge throught the power outlet
let the battery cell die and than charge it
see if this helps ( i have to try it too , just waiting for my cell to go dead lol)

SOURCE: my battery on my samsung g600 keeps going flat,

send the phone away for a warranty repair thats if its still in the 12 months warranty. sounds like the phone. since your phone is working with the charger in it, that points to the battery but if you bought a new one then it has to be the phone unless you are very unlucky in getting 2 dysfunctional batteries. But the best way around this is to send it away under warranty

SOURCE: I keep getting "charging paused. a battery to hot

You might need a new battery. I have a new phone with my old phone's battery and I'm still having that problem. To get it to charge, I usually take the battery out and put in back in. It usually only charges normally for a few days before happening again though.
