Astra a bit lumpy after battery swap, ECU remap????

My astra 1.6 auto 52 plate was a bit sticky at starting on the cold mornings, and the battery measured 12.21 v after standing overnight..

Popped into Halfords for a new battery, and they used a Draper memory saver.. Unfortnately it lost the clock, when I tried to start it was difficult catch amd both the engine warning light and the emissions warning light was stuck on. The engine warning light cleared after a couple of mins the emissions warning light was a little more persistant.

Am I right in thinking the ECU needs to learn the car again, is there a correct proceedure? It is driveable and the emssion warning light has gone out. How can I prevent these kind of problems next time?

Thanks

some cars retain the info others can take several miles before they remap themselfs , in that time they can perform like a bag of spanners

Its usually two "driving cycles" - gets up to temp, used throughout the rev range at light and high throttle, cools down. Some require more. Some define driving cycle as something a bit more complex, but I'd give it a couple of days decent driving. The "memory saver" is just another battery used in parallel to stop the loss of power - I'd worry about the competency of halfrauds if they cannot apply a battery the correct way to save the memory.

They probably did, but it's the same one they've been using for years and it's internal battery has had it...
