For these applications, you'd need to upgrade to a larger alternator like the Mean Green.īTW, Redarc is an AUS dual-battery isolators and is another choice besides IBS and National Luna. Keep in mind that our trucks' Denso alternator is rated to 100A. This would also apply if you carry multiple aux batteries in an offroad trailer that can be charged using the FJ's alternator. For marine applications where there is a bank of aux batteries (more than one), then the answer would be yes.

With regards to your second question on whether there is limit on the battery size (capacity measured in Amps-hours or A-hr), I'd say no for automotive applications as we typically only install one aux battery. Engine start usually takes a second or two so the 400A intermittent rating on the NL isolator may be sufficient a winch can draw up to 1,000A peak and may be used for more than 5 seconds at a time so the 400A would be inadequate as the solenoid overheats and fails. If you do not plan to combine both batteries while using your winch or to start your engine using the aux battery if the starter battery is dead, then the 85A rating of the National Luna would be more than sufficient to handle the current required to charge the aux battery when in the combine mode (engine running). Well, that depends on how you would like to set up your dual battery system. So, to get to your question: "Is higher better?". For the NL isolator, 85A is the max continuous current that the solenoid can handle without damage the 400A peak or intermittent is the max current that the solenoid can withstand without damage for a few seconds.

This isolator is rated at 85A continuous and 400A peak (intermittent).

Let's use the National Luna Intelligent solenoid as an example.

There are typically two ratings: continuous and intermittent. ) is the current-carrying capability of the relay or solenoid, expressed in Amps (A). The current rating provided by the various manufacturers (IBS, National Luna, Hellroaring. The combine function is usually accomplished by using a relay or solenoid. The isolate function prevents the starter battery from being accidentally drained flat when accessories are used when the engine is not running. Combine: the starter battery is combined with the aux battery when the engine is running so that both batteries are charged by the alternator. Isolate: the starter or primary battery is isolated from the aux or secondary battery when the engine is not running andĢ. Dual-battery isolators are designed to perform two functions automatically:ġ.
