I just changed battery, due to the old one was totally flat a 6 year old battery.
I wasnt sure what to get went down to local car store and picked up a 350 CCA heavy duty brand battery.
Put it in started up the car it was fine, left it running for a while until the temp needle was in the middle turn the car off.
15mins later wanted to go down the shop so i start the car up again, the idle drop until the car stall, the only way to hold idle is to press the gas pedal.

Was the battery i replaced the wrong type causing this to happen? or should i drive it around a bit when at stoping lights put my foot on the gas pedal to stop it from stalling and hope it would go away?

Thanks

 

this sounds like another fuel pressure or fuel pump/filter issue. i dont see a batt being the issue here

 

It could be just re-learning the fuel trims since the battery was disconnected. This can cause stalling for just a few drive cycles after changing the battery. Give it a few drive cycles and see if it settles down.

However..............I believe you are going to have other issues eventually as 350CCA is not enough in my opinion. Most people I know of are running at least 640CCA. Anybody know what the spec truly is? I forget....but I think it's 525?????????
I'm running with a 720CCA battery

 

750CCA for mine

 

350 is tiny... but the symptoms sound like fuel trims being reset.

 

Just drive it around a few times the ECU will relearn the tune.

Butt... I would return it as 350 CCa is too small.

 

What, CCA Rating should i get? it might fix this issues.

 

650 or better.

 

600CCA or better is enough.

350 CCA is WAY too low, even for non-freezing climates.

Just mind you, a healthy car should NOT stall, even when the battery has been unplugged. BUT ! the Factory ECU tune is pretty good at "masking" these symptoms AFTER a few drive cycles.

 

It may clear up in a few drives. Fuel trims, as stated. And also the battery may be accepting a strong charge, depending on how long it was sitting. The alternator can put a decent drag on the engine in such a case, but a long drive should charge things up fully.

In any case I'd double-check the battery connections to make sure they're clean and tight. A loose terminal clamp can cause these symptoms.

If none of this helps, worst-case your alternator may not be charging the battery and you'll end up with another flat battery.

 

This battery is below min spec. This is not some 1st gen Rx7 without power stuff all Rx8 are power window & locks and what not. Take it back like people say and get min spec battery. Then buy cleaning tool & spray for your terminals. Sometimes oil and crap get on the contact.

 

baking soda and water works just as good as any electrical cleaner on terminals.
