Practical Advice

When jump-starting, always ensure proper connection by attaching the positive clamp first to the positive battery terminal, and then the negative clamp to a grounded metal surface away from the battery’s negative terminal. Limit cranking to a few seconds at a time, allowing the jump starter to recover between attempts. Keep your jump starter charged regularly to ensure it’s ready when you need it most.
