What type of charger do I need?

You’ll find automatic chargers are the most convenient. Just plug in and it’ll do its thing. Manual chargers need more attention. The difference is in price: automatic chargers cost more than manual chargers.

To work out what size charger to buy, you need to know:

  1. Battery capacity
  2. How often you’ll charge (charging interval)

If you take out the RV on the weekend, or only a few seasons a year, a charger with an output current rating 10-14% of the battery’s rated 20 hour capacity will be enough.

When you need the battery recharged within 8-10 hours, a three stage, automatic charger, rated at 0% of the battery capacity may be needed.

Can't speak highly enough about the customer service I have just received. There was nothing too hard and absolutely prompt professional service. The cost great, and would recommend to anyone. I was stressed out and I was at a lost what to do but one phone call and nothing was too hard. Thank you Fast Fit and thank you Roger - Rose Baker


What charge rate should I look out for when choosing a charger?

Battery chargers are typically rated by their start rate - the rate measured in amperes (amps) the charger will supply at the start of the charge cycle.

When you’re choosing a charger, pick one between 10-14% of the battery’s 20 hour AH capacity.

For example: A battery with a 20-hour capacity rating of 225 AH will use a charger rated between 23-30 amps (for multiple battery charging, use the AH rating of the entire bank).

Charges with lower ratings can be used. But keep in mind this will increase the charging time.

Battery chargers: Tips and tricks

Charging a battery takes time. So plan extra time into your schedule when you set up your caravan or 4x4 battery bank.

For a flat battery (fully depleted), the battery will charge up quickly at first. It will then slow down. For an idea of how long it may take, 80% of your battery will be charged up in 20% of the total time it will take to completely charge your battery.

To cut down on charging time

If you are short on time, charge a few lower capacity batteries in parallel instead of one large battery of the same capacity. These will charge in less time than it would take to charge the large battery.
