[QUOTE="shizzzon, post: 8640177, member: 590338"] The context they are telling you this is in this context- If you have a single starting battery and a single alternator (doesn't matter it's size, stock or larger..), having the battery with loose connections or POOR performance DUE to age of battery will increase resistance at the battery. Since everything is connected to the battery, the battery must be in good condition and connected tight. Having one or both of these conditions go sour forces the alternator to ramp the voltage up to "bleed" through the resistance so the battery finally sees the voltage it suppose to see. The downside to this is since everything is connected to the battery, electrical will flow through all the wires in use past the battery at the maximum output voltage the alternator is set to at that time. Meaning.. if you are reading 17v somewhere else, then that means the regulator is outputting that high of voltage just to overcome some issue at the battery. This is pretty serious. This isn't a voltage spike you should keep allowing. Adding a new battery of course will help eliminate the spikes.. But without attempting to re-secure your connections at the starting battery OR replacing it altogether, adding additional batteries will only temporarily solve the issue until the new battery(ies) bleed into the starting battery for whatever reason eventually damaging either the alternator from overworking it or never fully charging the newly added batteries. The notion your starting battery is too small isn't the correct answer but it's CAPACITY that is available may not be enough BECAUSE of other factors or it could be very well too small altogether because the car is requesting simply too much capacity from it during a cycle before recharge therefore concluding it's capacity is too small.
