Lithium Battery Habitation

Lithium Batteries Caravan or Motorhome

Fancy a better quality leisure / habitation battery?

If you are based in the South West, we supply and fit Lithium Batteries, read on for key information.

Leisure Batteries come in many different shapes & sizes.

Physical size is important, double check the battery location, your new battery will need to fit into the space provided in your caravan or motorhome. Lithium batteries can be fitted on their side, space isn’t usually an issue.

Amp Hours (Ah), this is the rating a battery is given, which indicates how long your battery will last, based on your power consumption. In theory a 100 Ah will deliver 1 Amp for 100 Hours.

A key factor often missed is gases given off during charging. This is important when the battery is located inside the habitation area of your caravan or motorhome. Your leisure battery should be located in a sealed unit, which is vented to the outside. If it is not vented externally, risks include:

  1. Risk of explosion / fire, gases are flammable.
  2. Risk to your health, gases are poisonous.

Cycle Times (CT). This is how many times your battery can run low and be recharged. Think of this as your Return on Investment (ROI), how many recharges will you get for the purchase price of the battery.

Changing. Leisure Batteries are usually charge in one of three ways:

  1. From the engine’s alternator when you are driving.
  2. From a charger connected to a 230v mains hook-up.
  3. From solar panels.

Leisure Batteries discharge (run flat) through using on-board 12v devices inside lights is the obvious example, but don’t forget, most appliances (fridge, heater, cooker) need 12v to run the PCB control panel and ignite the LPG.
