Charging A Deep Cycle Battery
There are many variables that affect how well, or how long, your battery will last. You should let it deep discharge and should keep it charged to a full capacity at all times. Also, make sure that the fluid never drops low enough to expose the plates. However, one of the best things you could ever do for your battery is to learn how to properly charge it. By charging a deep cycle battery the right way, you could end up with a battery that lasts beyond your expectations.

The Right Way to Charge a Marine Battery
Allowing a marine battery to charge slowly is one of the best way to increase performance and longevity. Many of the new marine battery chargers use a three step charge. The first step provides a bulk charge, the second is the absorbing charge, and the third is geared toward battery charge floating, which simply ensures that it does not gradually lose the charge. If you have a battery charger that is able to charge in all three stages, your battery will charge up faster and more fully. This, in turn will increase the battery life and usability.
How Often Should You Charge A Marine Battery?
When it comes to charging a marine battery that is new, you should charge before it is discharged 20%. This will allow the battery to finish building up the plates that will allow it to hold a charge longer. As the battery ages, you can let it drop slightly more, but you should strive to never allow it to drop below 50%, especially since it does not normally take very long to recharge a battery. However, the length of time it will take for you when charging deep cycle battery depends on the charger you have and the battery rating itself. Some may take just a couple hours and others may take much longer.
Which Charger Works Best For Marine Batteries?
Charging marine batteries is not difficult if you have a good charger to work with. If you need a charger that is ideal for AGM battery charging, you should consider a smart charger. Although pricey, it may save you money in the long run. If you do not want a smart charger, you still have options.
