Battery World looks at best RV power choice with gel, AGM, lead acid batteries

On the road and on the water the effective battery system which is easy to maintain and repair is the best choice.

Peter Couvaras of Battery World is not really stating the obvious when he says that. For example deep cycle gel batteries are technically superior to Absorbed Glass Matt (AGM) batteries.

Both types are sealed, don't vent and suit land and sea. That means they suit Recreational Vehicles (caravans, motorhomes and campervans) and motorboats and yachts, Peter says.

But the gel battery has a narrow charging band and must be set up exactly to specification. So problems in remote areas may be beyond the range of the local fixit options, he says.

Gel is technically superior but is the most "fussy" and has to be charged in a narrow voltage range. This means that the correct battery charger for this task must be mounted in the caravan or Recreational Vehicle which is to use the gel system.

Its popular counterpart the AGM battery is more forgiving in its charging band. Standard chargers do the job and if it goes flat while camping, there are more options for charging it back up, Peter said.

The sealed AGM battery is popular with Battery World shoppers Peter says because it has 80-90 percent of the qualities of the more expensive technically superior gel battery and provides more flexibility.

In the marine environment there are further variables which decide the battery choice. In yachts a gel battery system is best and safest, he says.

In a racing yacht there is no argument, a sealed battery is the only safe and acceptable way to go in an electrically dangerous saltwater environment. Yachts reach high angles or heel and in a worst scenario can roll right over.

Sealed batteries have unique advantages as they will even work upside down and under water, Peter said.

But in stable motor cruisers the working environment is more forgiving and cheaper wet cell lead acid batteries can be used, he said. Both the land and sea environments have common safety requirements.

Batteries must be secured in a safe appropriate location. In the case of wet lead acid cell batteries that is a fully sealed and effectively vented compartment. Peter says that wet lead acid batteries and the gas they vent should be regarded as a health risk and treated accordingly.

This applies in caravans where the battery/ies may be stowed in the caravan boot or in a locker under a lounge seat inside the caravan. Motorhomes tend to have a more varied approach to the location of storing batteries safely.

Peter says battery banks have an equalizing effect. For example if a new battery is introduced separately to a bank of batteries which are three years old then the new battery will take up the profile of the older batteries.

This means that a series of batteries should always be replaced as a unit, Peter said.

Of the three types of batteries, wet cell lead acid batteries are the cheapest.

Gel is the most expensive, and the Absorbed Glass Matt type is middle of the road.

There is a difference in price between various manufacturers, and this is generally reflected in the price. The old adage you get what you pay for applies.

At Battery World, we only supply quality products that are supported by a national warranty Peter Couvaras said.

Solar panels are often used in the camping environment, but $1000 per panel is the price area involved and battery power relates directly to available sunlight.

For caravans and Recreational Vehicles bound north this brings up the matter of shade. Camping in the open is a hot business.

Most people prefer to find shade. Which leads to portable solar panels being used which can be moved to collect sunlight.

Unfortunately this also raised security concerns as the panels are expensive and attractive to thieves.

We find that most people free camp for about three days, Peter said.

The longer-term remote area campers who are really serious get a generator. We are setting up a generator package now with battery pack which provides more reliable power. , he said.

We think 12 volt is the way to go for people on the move in their Recreational Vehicle fit out and the accessories they chose, Peter Couvaras said.
