Powertech 5 in 1 manual
Its handy for looking up the charge time which is 34 hours (or 48 hours if its the first charge).
The jump start instructions are also important as they remind you that the black negative cable must never be connected to the battery. Instead, first connect the red positive cable to the positive terminal on the car battery, then clamp the black negative cable to a non moving metal part of the vehicle. When disconnecting do it in the reverse order by disconnecting the black negative terminal first, and then disconnect the red negative terminal.
Its best to read the manual before you attempt any connections you are not sure about.
