Which Caravan Battery is best for me ?
Over the years we have had many customers call in at our
West Yorkshire depot here in Halifax, looking to replace their battery, for the
caravan. We have all sorts of people and types of people who share in the
outdoor life and enjoy caravaning, either for their holidays or just a weekend
away. These days caravan

We very often have customers attending with a car battery,
and say that they have used it for four or five years without any problems. In
this case I try to match the old battery as best that I can, because I know
that they are happy with that car battery and it is no use confusing the issue.
Others come to us with a leisure battery and want to upgrade to a larger size
amps. We have no problem with that as long as the leisure battery fits into their
battery compartment. The usual upgrade is from a 85 1mp battery to an 110 amp
battery. I think this is because that the price has dropped to an acceptable
level for people to afford, due to competition from the internet.
12 volt Car Batteries
In general the two types of caravan batteries are of
different construction internally. They certainly look the same, indeed not too
long ago narrow boat owners used a bank of 644 truck batteries to power their
boats, both as a starter battery and a storage battery for their electricity
needs. But the main difference is inside the battery in the lead alloy plates.
The car battery is used mainly for starting your car, and so the plates are perforated
with small holes. This gives the battery a larger surface area to give the
battery a high boost when starting a car. As I have said though some people do
use car batteries and have done for years, so why change? Car batteries give out a high current of
around 200 amps over a short time period as you start the engine. This drains
the battery to a low level of charge especially in cold winter weather, but
this huge power loss is replaced immediately by the cars alternator and so the
battery never becomes fully discharged. It is known as having a shallow cycle
of discharge and charge and the car battery is so designed for that purpose.
12 volt flooded lead acid leisure batteries
When we start to talk about the leisure battery we have some
sub categories to look at. The first one is the battery that we all know as a
leisure battery because it tells us on the label? It is as simple as that. Over
the past ten years the leisure industry has grown at a very fast rate. We can
all see the large number of caravans and camper vans on their way to a holiday
destination, whenever we are traveling. This means that the

The battery industry is no different. Manufacturers such as
Johnson Controls have come up with better storage cells inside the leisure
battery as compared with the humble car batteries. The cells in the leisure
battery are now much thicker and so will hold more storage charge. These
batteries are now used in the majority of these vehicles used for holiday
purposes. The 110 amp leisure battery is a prime example, although the 115 amp
battery is now becoming more popular because of the electric caravan movers now
in use.
The leisure battery does not have to do such a job as the
car battery, (but just to confuse matters I know that some 4X4 owners are now
fitting 110 amp leisure batteries to their vehicle, as a starter battery and to
operate things like winches and they have proved to be very successful). The
leisure battery is designed to supply a much lower current to power the light s
and other electrical equipment, including the TV and water pumps. This type of
battery has a larger and deeper cycle than the humble car battery. In simple terms
the battery will drain more and then charge back up again using bigger cycles.
If a car battery is discharged below 80% then the solution that covers the
cells will break down and fall to the base of the battery, causing it to short
out and then battery will have to be replaced, it will not recover.
12 volt AGM sealed lead acid batteries
These are the next step up to the flooded lead acid
batteries. They are probably the best choice battery to use. The batteries are
sealed and can even be used on their sides, it will make no difference. These
batteries are also a true deep cycle battery. They will take a heavy discharge
and totally recover when charged. These are the batteries that I would
recommend. The only drawback is the price; they are much more expensive than a
standard leisure battery. But will probably last five or six years, perhaps
twice longer than the free flow lead acid leisure battery. The AGM battery is
also more suitable to be used with solar panels, something that is becoming
more popular amongst caravan enthusiasts all over the world.
