[QUOTE="audioholic, post: 4138552, member: 549629"] The diagrams are midleading for more than one reason. Its an 'example graph' that people take as a specific test, which leads to many false conclusions. Yes, if the car is brand new so the battery is as well, you aren't likely going to see people recommending a new batt. But how often does that situation occur? Its much more often a used car, an old batt, etc. The idea of recommending upgrading the batt before the alt is simple, make the current system as efficienct as possible before worrying about upgrading the power source. Its the same idea as upgrading the big-3, to ensure your charging system is as efficient as possible to handle and maintain the greater load on it than it was originally designed to handle. If the batt is new, no prolly dont need to bother 'upgrading'... but I think you are saying you see this situation here alot, people saying to 'upgrade' an already new batt. That is not what is meant by saying to 'upgrade' your batt first. When we answer questions here, we sometimes have to assume to reader will use some common judgement and realize if his batt is already new, the 'upgrade your battery before your alt' comment doesn't really apply. Unless the system is excessively large. Running a large stereo thru a relatively small batt, even with a huge alternator to create the power, will cook that poor little batt. Ive seen it, hell Ive done it.
