battery is not what a Leaf needs. Seems a lithium of some sort would do great.
Another site said the DC/DC converter can put out as much as 120amps. The
brakes and other systems that run on the 12v system might need a boost if the
battery fails and braking is very important. After finding out that the lead
battery is under charged I suspect an undercharged lithium battery might fair
much better and for longer. Lawrence Rhodes
I don't "buy" it, Lawrence. Too many of his comments are just opinions;
not facts. Just a few glaring points:
- A 12v battery *will* reach full charge at 13.0v; it just takes a long
time (like a week or so).
- He ignores temperature compensation. The Leaf does temperature
compensate its charging.
- He ignores aging. The older the battery, the lower its basic charging
voltage.
- 14.4v will easily fully charge a 12v battery. Remember, if it's
holding the battery at around 13.0v, it's already close to full; so it
takes very little time at 14.4v to finish the job.
