Frequently Asked Questions (FAQs)

1. What is the difference between a deep cycle battery and a car battery?

To achieve a large amount of current, a car battery uses thin plates in order to increase its surface area. A deep cycle battery is designed to provide a steady amount of current over a long period of time. A deep cycle battery can provide a surge when needed, but nothing like the surge a car battery can.

2. Can you charge a deep cycle battery with a car alternator?

Most vehicle alternators will never properly and fully charge up a Deep Cycle battery so invest in a good charger or a solar arrangement with a charge controller/regulator with at least a three stage charging control (many chargers are now 6 or 7 stage affairs).

3. What is the advantage of a deep cycle battery?

Advantages: Lighter and smaller than flooded lead-acid batteries for the same capacity. No regular maintenance or topping-up required. Low internal resistance allows very fast charging, with reduced energy loss.
