How does a battery selector switch work?
Your system works something like this: the battery you’ve selected powers all of your 12-volt DC systems — engine ignition, lights, electronics, stereo, etc. The alternator will charge your battery back through the switch, so the battery you’re using underway will be constantly recharged while the engine is running.
What is a dual battery switch?
Using a Dual Circuit Plus battery switch prevents the possibility of draining the engine batteries with house loads. In effect, the engine battery is left with only one purpose, to start and run the engine. When the switch is turned to COMBINE, the alternators will charge both the engine and the house batteries.
How does Perko switch work?
The Perko Single Battery Disconnect Switch permits the battery to be shut off from the electrical system when the vessel is not in use. They can also serve as an emergency main disconnect switch in the event of an electrical problem.
Where do you mount a battery switch?
Just in front of the battery and behind the seat. That way you just have to pull the seat to access the switch. That way it’s close to the motor and doesn’t add too much extra wire. Remember that you need at least #2 battery lead.
How do I charge batteries with Perko switch?
Just put the Pos (+) wire from the charger to the “C” (common) terminal of the Perko and run the switch in “Both”. This is the same s the alternator charging. Just make sure the Neg (-) of the charger goes to the engine or the neg (-) of the main/starting battery.
Can you run two alternators one battery?
You can run two batteries on the same alternator. Alternators protect against excessive current drain and aren’t affected by multiple batteries. In the process, the power level in both batteries remains equal. The alternator registers these two batteries as a single large battery and charges them the same.
Does Perko switch both batteries?
This means you are charging both batteries at the same time. Now if you want to sit and listen to the stereo with the boat off move the perko switch to position “1”. This isolates your 2 batteries leaving your starting battery fully charged for when you start.
Is it OK to charge batteries in parallel?
When charging batteries in parallel, you aren’t charging the voltage of the batteries, but, rather, the amp-hour capacity of the batteries. In parallel, batteries have an increased AH capacity even when voltage is the same across each battery.
Can I charge two batteries at the same time?
9. Two Batteries in Parallel, One Charger. Batteries connected in series strings can also be recharged by a single charger having the same nominal charging voltage output as the nominal battery pack voltage.
