How often should I have my RV electrics & brakes serviced?

Highway Auto Caravan Servicing recommend two types of service. These being the first service and the annual service. The first service is carried out in the first 12 months or when the caravan or trailer reaches 1000-2000 kilometres. This may be a basic service, but it is an important one.

Once that milestone is reached it’s essential to schedule annual services for your RV. As the name suggest, the annual service should be carried out yearly, or every 10,000 kilometres, whichever comes first. These services are thorough and help prevent more significant damage or delays while you’re on holiday. Don’t be tempted to skip the annual service if you haven’t taken your RV out for a while, even when not in use there is deterioration happening in various underbody areas as well as braking systems.

Caravan & RV Multiple Battery Systems

How many batteries do I need?

Batteries can be damaged if they are overly discharged on a frequent basis. Common lead acid AGM batteries have a rated cycle life of 500 at 50 per cent depth of discharge (DOD) and more than 1200 at 25 per cent DOD. This means, theoretically, when a battery bank is doubled in size, it will reduce the DOD from 50 per cent to 25 per cent and the lifespan of the batteries will extend more than twice! So what do we get? A battery system that costs less money in the long term and is also larger in capacity to operate more items for longer.

Rule of thumb: If a battery bank goes down to below 12V quite often, it’s time to consider increasing the capacity of the whole bank.

Defining the amount of energy available in a battery is a complex task. There are many things to consider to accurately monitor the state of your batteries; battery age, discharge current and temperature all influence the actual battery capacity.

Highway Auto Caravan Servicing have the latest battery analysis equipment to accurately calculate your battery condition and remaining life.

Your Vehicle Alternator Can Charge Multiple Batteries.

Will the alternator fully charge all batteries?

The limitation is that a battery below a remaining 20 per cent charge is effectively dead. Further, it may have a life of only months if discharged repeatedly below about 40 per cent remaining charge. Battery makers typically quote 50 per cent. Thus, if a battery is charged only to 80 per cent and discharged to 40 per cent, only 40 per cent of its nominal capacity is available for use. Batteries in caravans may not even reach 65 per cent charge. However, If managed correctly some of these limitations can be resolved.

What is The Best Method of Charging Caravan Battery Banks?

First consideration is to ensure that all positive poles are common and therefore all negative poles will be common. Voltage measured at the termination of the battery bank should be in the region of 12.5 to 14.5 volts.

The next consideration is to have the correct connection protocol to the vehicle battery and this involves a switching process to isolate the vehicle battery when the engine is not running. Otherwise the caravan electrical load could flatten the vehicle battery.

Next, be aware that the vehicle alternator will charge the fittest battery in the bank first and down the line it goes. If one or more of the battery bank are degraded or close to end of life then they may not receive any charge at all. It is good policy to have all batteries tested for condition and life expectancy before assembling a bank of batteries. Theory has it that all batteries will be charged, yes but only strong serviceable batteries will obey that theory. Battery Changing Management System Tap Here
