[QUOTE="d0dja, post: 1020289, member: 2244"] IMHO points 1 and 2 they're talking kak. Why can a modern alternator not fully charge a battery? If the alternator can push the terminal voltage over 13 or so volts, the battery will charge. IF it can take charge ... but the problem is most likely with the battery. And it seems modern batteries last 2-3 years tops, then they're toast. The days of a working ten year old battery are very much over. But those battery centres sound like they're seriously just making up stuff based on barely understood concepts. Note: speaking as an elec eng with general understanding of the topic, not as a battery specialist [/QUOTE]
