Re: battery chargers
A deep cycle battery will last longer when using a slow charger rate rather than a fast charge like most chargers for regular batteries. The fast charge causes extra heat on the plates in turn causing faster plate corrosion on the positive plates. The 20% rule should be used when charging a deep cycle battery. Choose a charger where the maximum current (in amps) is less than 20% of the Ah rating. For example, an Interstate SRM-27 is rated at approximately 100 Ah, so a 20-amp charger should be the maximum. Also, it is best to use a charger that is adequate to recharge the battery within 10-12 hours
