Question I have an old NEC battery charger, which list its output as:
Vcc: 13.0V- 0A/1.7/2.8A
VCV: 13.0V - 4.1A/2.4A/0A
Since the alternator output is like 14.2 V 7 unknown amps, can I use this with a timer to keep the battery of a classic car charged over the winter - if connected through a timer that limits on time to 5-30 minutes a day?
Answer Sorry, but that won't quite work. To fully charge a car battery, it has been traditionally agreed that a voltage of 13.7V is required. But to complicate matters, there are now many types of chemistry for car batteries, resulting in several different voltage requirements. If you want to see a quick description of this, look at this webpage:
