Hi,2001 Boxster 2.7,been on battery tender ( C-tek ( for 5 months ) charger & cables getting very warm so disconnected it. Tried starting car,it did struggle but managed to start ,but then the alarm started going off. Is this a sign the battery has had it? Not been run for a while. Question if so how do I change the battery without setting the alarm off as its incredibly loud?
Thanks
Thanks
