Electric Trolling Motor Battery

Electric trolling motor battery Selection is very important ,it directly influence the power of trolling motors . POER recommends to use 12 volt deep cycle marine batteries or battery system  to operate trolling motors. Firstly ,let us know more about the car batteries and deep cycle marine batteries .

Car Batteries

      Car batteries are designed to provide a maximum amount of current in short bursts. These batteries are designed this way to provide the needed current to turn over the cars engine. Then when the motor starts the alternator takes over and provides power for the car. With this type of system a car battery may never be drained more than 20% of it's total capacity. When used this way a car battery can last for years. Not to get too technical but a car battery uses thin plates in order to increase it’s surface area and provide power. 

Deep Cycle Marine Batteries 

      Where car batteries are designed to provide short bursts of current a marine battery is designed to provide a steady amount of current over a long period of time. A deep cycle battery can provide a surge when you need it but not near the surge a car battery can. Deep cycle batteries are designed to be "Deeply Discharged" over and over again. Please catch this! Deep discharge of a car battery over and over will ruin the battery quickly!  Marine deep cycle batteries can withstand several 100 total discharge/recharge cycles. While a car battery is not designed to be completely discharged. So how do I choose the right type of deep cell marine battery to meet my need?

Choosing The Right Battery
      

      This can be a fairly simple process if you haven't added additional aftermarket electrical equipment to your boat since you bought it. If everything is status quo and your current batteries were meeting your needs then replace them with the same Amp Hour rated deep cell battery. But, if you have added additional equipment your minimum Amp Hour requirement will naturally increase. This is where you need to discuss your current needs with a trained battery technician.
