don’t. We don’t recommend it, and here’s

why: only the surface area of the battery plates

can be quick charged. A lower current charges

the battery more uniformly. That means better

performance. Also, excessive charging rates

increase the chance of overheating, which can

mean battery damage.

The rule of thumb is to charge a new battery for three to five

hours at a rate equal to 1/10 of its rated capacity. But

there are a lot of exceptions to that rule, as this table shows:
