Leisure batteries. Noice. But what size do you get?

Firstly, my apologies for the sound quality on this video. The old mic has been sacked and replaced by Dido Harding. I couldn't think of anybody better for the job.

This is the second in my fascinating series of videos about the exciting world of leisure batteries. In the last video, we looked at the types of battery commonly available for your motor-home. In this one I take you through (in exhausting detail) how you go about choosing a battery with the right capacity (expressed in Amp hours, or Ah) for the type of motor-homing you do, i.e., mostly hooked up, always wild camping, or somewhere in-between.

In the video, I explain that to get to an estimate of the size of battery you need, you will have to list all your accessories that draw 12 volts, what current they draw and how long they are in use for each day (roughly).

To help you do this, I have prepared a sheet for you to fill in, which will automatically calculate the minimum size battery suitable for your power usage. You can access and download it here:

If you're a bit geeky like me, then here are some electrical formulae:

Power (W) = Volts (V) x Amps (A)
Amps (A) = Power (W) / Volts (V)
Amp hours (Ah) = Amps (A) x hours (h)
Amps (A) = Volts (V) / Resistance (Ohms)

Thanks for watching!
