We use 3 types of batteries in our electric tugs, divided into wet (traction), maintenance-free and lithium batteries. Each type of battery has its advantages and disadvantages. Wet batteries, for example, have a lot of capacity, can withstand deep discharges, have a long lifespan but must be regularly topped up with demineralized water.
Maintenance-free batteries have the advantage that they do not need to be topped up and are therefore maintenance-free. The disadvantage is that these batteries are less able to withstand deep discharges and have a shorter lifespan than wet batteries.
Lithium batteries are increasingly being used in our electric tugs because they are becoming more and more interesting in terms of price compared to traditional batteries. Lithium batteries are maintenance-free, have a very long lifespan and can be charged in the meantime. The disadvantage is that lithium batteries are relatively expensive to purchase compared to traditional batteries, although the return on investment is high.
