Trolling Motor Battery Life Calculator

Battery amperage hour rating and a motor s amperage or watt draw.

Trolling motor battery life calculator.

The guy told me that this battery would be more than adequate for my motor. Use a calculator like this one to determine the wire gauge you should be using. Calculating your marine or deep cycle s battery s life is not as difficult as you think it is. How to calculate battery life.

Battery life calculator so if you have a 24 lb thrust motor and your battery size is 33ah you can go at high speed for 1 2 hours or about 72 minutes. This unit measures how long a battery can maintain a consistent amperage output. Using a motor on lower speeds will increase battery life. However this is only true for 12v powered trolling motors.

Using a motor in strong currents winds or heavy loads will shorten the battery life. A better estimate of this runtime can be achieved by dividing the max amp draw in half and using that answer in the equation. Then divide the battery s amperage hour with its amperage draw. But normal lifespan expectations for trolling motor batteries are as follows.

You just have to take note of your marine battery s amperage hour rating and amperage draw. Essentially they more power your trolling motor draws and the. Using a variable speed motor helps to regulate the speed of the trolling motor. A trolling motor battery life is something that manufacturers do not really offer a warranty for since it.

It s either a deep cycle or dual purpose battery with deep cycle capabilities. Marine batteries are rated by amperage hours. Please note that a larger trolling motor doesn t translate to a longer boat. So it ll run various power hungry devices as needed on a boat while the battery still holds a charge.

After the 72 minutes your battery will still have about 10ah left in it but if you want it to last you will need to stop motoring and charge it back up as soon as you get home. A bigger boat length would require a higher voltage battery say 24v or 36v. Marine agm deep cycle batteries 4 to 7 years wet or flooded batteries 1 to 6 years gel batteries 2 to 5 years. The amperage draw of a trolling motor increases as the speed of the trolling motor.

Greetings i went out today for the first time with my new 57 lb. If you need seriously long run time for your smaller boat it may make sense to buy a 24v or 36v motor. Buy a larger motor. Larger 24v and 36v multi battery trolling motors are able to provide the same thrust as smaller motors with less amperage draw which results in longer run times.

Trolling motor batteries may last between about 2 6 years depending. Thrust trolling motor and a brand new duracell ultra sli24hmdp rv marine battery i purchased at batteries and bulbs.
