Stuck reboot loop Iphine 4s

I change the iphone 4s battery with a new one by iFixit, switch on the phone and all was ok. After few minutes the phone automatically reboot.

I try to make hard reset , but the phone after few time from the start still reboot.

All is ok wifi and mobile connection works.

I put back the original one battery and all wroks correctly.

How I do to put the new one and make the phone works.

I try switch off the mobile with the new one and charge it all the night long, switch on and the perentage was 95% not 100%.

Help me please.

Thanks in advance.
