Will I fry my batteries if I leave the charger plugged in over long periods of non-use (like storage)?
No. Minn Kota's on-board chargers float the battery voltage between 13.2V and 13.5V in the "maintenance" stage (3rd stage). This will allow you to keep your battery charger plugged in for long periods of time without "boiling the battery dry." Note: It is important to check the electrolyte level approximately every 30 days. Batteries should be filled after charging and the electrolyte level should be even in all cells and below the fill well in each cell. If the battery plates are exposed before charging, then add just enough water to cover the plates. If the battery is overfilled before charging, then it may overflow during charging.
Are Minn Kota chargers waterproof?
Yes. But they should not be operated while immersed.
Do I need to disconnect the 24-volt connection when using Minn Kota chargers?
No, the jumpers can remain in place. The same holds true for a 36V connection.
Can I charge two batteries on one charger bank?
Yes, but it is not recommended. It takes double the amount of time to charge two batteries and the charger may get hot.
Can the charger be mounted in any position?
Yes.
Can I extend the charger output leads?
Yes. A terminal block is recommended, but a soldered splice covered with heat shrink will also work.
Can I leave my Minn Kota charger plugged in all the time?
Yes, but the electrolyte level should be checked every 30 days.
What size fuses are used on Minn Kota chargers?
If the fuse holder is black, then a 30 amp AGC 32V automotive fuse should be used. Recently, all chargers have changed to a yellow fuse holder which uses a 30 amp AGX 32V automotive fuse. An AGC can be used but may not fit as well as the AGX.
Can I connect two charger banks to one battery?
Yes, this will charge the battery almost twice as fast. However, the water in the battery is more likely to evaporate with higher charging currents. Thus, the electrolyte level should be checked more often. The maximum safe charging current on a regular battery is 20 amps.
How warm do Minn Kota chargers get?
They may get warm in an enclosed area. The maximum recommended room temperature is 122° F. If the charger seems to get "hot", try opening a hatch to help cool the charger.
What is the warranty on Minn Kota chargers?
All of the chargers have a full three-year warranty.
