How does a split charge relay work?

A split charge relay kit uses a heavy-duty make-or-break relay switch to connect the leisure battery to the starter battery. The switch is activated when it receives a current greater than 12V whilst the engine is running.

How long does a split charge relay take to charge a leisure battery?

The alternator provides 70A so the battery bank will take a little less than an hour to fully recharge.

Does electric hook up charge leisure battery?

If you use mains hook-up, the leisure battery will be being charged by the on-board charger, and in most caravans and motorhomes this is not a very sophisticated system. It can actually damage the battery, this time by over-charging it, causing gassing and drying out of the battery.

Can you run an inverter off a leisure battery?

Inverters connect to a 12V DC supply and convert it to a 230V AC output. They allow mains appliances to be run from a leisure battery or Caravan 12 volt supply. They’re great if you’re wild camping or likely to be using sites that don’t always have a mains hook-up but they do have limitations.

How do you connect two leisure batteries together?

To join batteries in parallel, use a jumper wire to connect both the positive terminals, and another jumper wire to connect both the negative terminals of both batteries to each other. Negative to negative and positive to positive. You CAN connect your load to ONE of the batteries, and it will drain both equally.

What should a 12 volt leisure battery read when fully charged?

12V or lower An alternative method of checking the charge level of a battery is using a hydrometer to measure the electrolytes in the cells. The reading should be between 1.1 (discharged) and 1.28 (fully charged).

How do you know when a leisure battery is fully charged?

If you are looking at the control panel straight after plugging in the EHU, then yes, a fully charged battery will register 14.3 volts with a current of 5 amps or so. But if the batteries are already full (charged by the alternator) and the charger senses this, the current will fall back to around 0.5 amp very quickly.

Does 240v hook up charge leisure battery?

For those who spend any time on campgrounds with a main power supply, an AC hook up (240v or 110v) is a perfect way of recharging leisure batteries. With the right set up, you can basically plug in the camper to a mains supply.

Do you need a battery isolator with a DC-DC charger?

We recommend DC to DC chargers over isolators because they protect the vehicle’s alternator, and maximize the battery’s lifespan. DC to DC chargers provide a multi-stage charge to the house battery and push more charge current than an isolator.
