AM i missing some thing ? , changing out the battery as was getting a few low battery warnings , so bought a new amg battery to replace the old 6 year one it was also an amg , disconected the old one got it out , put in new one hooked it up , nothing car wont start , i had checked the voltage before i put it in reading was 12.8 volts what am i doing wrong ?

 

Does it have enough CCA? AGM battery probably doesn't matter much in terms of chemistry to start, you just need the specifications to match.

 

Yes specs seem to match , iam at a loss unless it needs to be programmed in as its stop start

 

All fixed , in my haste had forgoton to re conect a black lead to battery a senior moment. blush

 

Hey still a good cheap fix anyway!!

Even though you successfully installed your new AGM battery, odds are that it's not fully charged. Many batteries sit on retailers' shelves for month's slowly discharging.

Because I don't drive enough every day, I keep both of my Jags on CTEK battery maintainers to prevent electrical gremlins.

 

yes thanks saved about $80 bucks

 

yes well aware but thanks had took a reading prior to install battery gave 12.8volts so all good , will be hooked up tomorrow to charger as installing new rear discs , and put car into service mode via isoft code reader to keep voltage up
