If you are in the market for a deep cycle battery charger then continue reading.
What exactly is a deep cycle battery?
A deep cycle battery is very different from other batteries because they are specially designed because they can be run down all the way and fully recharged with minimum loss of capacity. This is why a car battery is a poor investment for marine applications because a car battery will lose capacity once it is used and recharged. A deep-cycle battery will also outlast a car battery by 2-4 hours. Of course the life of your deep-cycle battery will be determined by the storage, frequency of use and climate conditions.
There doesn’t seem to be a large selection of deep cycle battery chargers on the market. So you should really read plenty of reviews on them before purchasing them. You should also only purchase from a reputable store that will allow you to return it if it doesn’t work out well.
