1.Battery Terminologies to know before going ahead
The amount of electromotive force needed to move one ampere of electric current through a wired circuit. It is also known as potential difference.
The measure of electric current through the electric circuit is known as ampere or amps.
Amp Hour- Ah
The measure of the battery’s electrical storage capacity is calculated by multiplying the amount of electric current (ampere) by discharge time (hours).
The amount of total electric power stored in the battery is known as watt; multiply ampere by volt to calculate it.
The total number of times a battery can charge or discharge before its capacity is reduced to 80% of its original rate.
2.Things to note when choosing a fish finder battery
There are many features to consider when choosing a fish finder battery as they mainly depend on your needs and requirements, but some essential features are a must to consider, which are listed below:
