Batteries don’t just differ in terms of their voltage, energy capacity, and other electrical ratings. Different basic battery designs are also more suited to particular kinds of duty than others. This means that even two batteries that look the same in terms of numeric specifications can easily be far different within.
Many of the larger batteries sold in Australia today, for example, are designed mostly for starting cars and personal trucks. This means being able to crank a starter motor quickly, sending an intense jolt of electricity for a couple of seconds to turn over a powerful, fist-sized motor that puts a much larger one into motion.
A battery of this kind will therefore be designed to deliver a lot of current quickly and reliably. In order to achieve that goal, sacrifices of other kinds will be made, with designers specifically giving up other potential advantages in the process.
In the case of the average car battery, this means a battery design that is not especially adept at giving up the whole amount of energy within. Instead, a car battery will normally be designed to dish out just a fraction of its overall capacity and to do that reliably, over and over again.
A starter battery that is run down too deeply and then recharged, in fact, will suffer a severely shortened lifetime because of it. Most car batteries will hold up the best if they are not regularly drawn down beyond eighty percent of their ultimate capacity, with every charging cycle that goes beyond that cutting down on longevity.
On the other hand, there are batteries that are designed to withstand this kind of usage with no issues at all. Often referred to as a “marine battery” or a deep cycle battery, a battery of this sort can be safely tapped of almost all of its power before recharging. While every battery will suffer some shortening of lifetime from recharging, a battery of this kind will hold up to these cycles far more ably than those meant for regular use in personal vehicles will.
Because these two kinds of batteries are so fundamentally different, picking the right one for a given application is important. The kind of Battery Supplier Brisbane residents have access to will invariably stock products of both kinds, so that any particular application can be accommodated. In some cases, as with recreational vehicles that use one battery for starting and another for powering appliances and the like, both sorts of batteries will even be needed.
