Not with batteries. The simple truth is they are not efficient devices, as they need energy to produce energy. What needs to happen is make what uses batteries much more efficient, that would reflect to longer lasting batteries.
Thanks for the views. I am going to generalise a little:
For modern P-cars from say, 993 and on most people will want matching numbers, straight, even preferably Australian delivered. However, back before the 964 many P cars were mixed and matched as prices were not unobtainium like what the current market dictates. So like everything it is horses for courses. If you want to track the vehicle and accept that it is a thrasher, then one may not mind the checkered history. However, if the car is something that you have worked many years to earn, then you probably want to have the straightest example your budget allows for.
Mostly specialized forums are solid places to dig around for information before laying down the money, so thanks for the views.
