The amount of time required to charge a Norsk Lithium ice-fishing battery depends primarily on two factors.
First, the battery’s capacity, expressed in Amp Hours. Second, the output of the charger, expressed in Amps.
The time it takes to charge a battery comes down to how many amp hours need to be put back into the battery and how many amps of output coming from the charger.
“If a 20 Amp Hour battery has been discharged 50%, 10 Amp Hours need to be replaced. If the charger being used to recharge the battery outputs 2 Amps, the battery in question will be fully recharged in 5 hours.” – James Holst
The larger the lithium battery’s capacity, the longer it will take the battery to charge. Here are the charge times you can anticipate.
