    Default Maintaining my dual battery

    Hi All,With the current petrol price, I have a little run around for work and back, And now the bakkie is standing at least a week at a time,I saw this Sunday that my second battery is not holding charge, and even main battery goes a bit more flat than usual.So here is the thinking: Get one of these Midas chargers, .8/4 Amp DC Smart Battery ChargerProduct Code: PSA004Category: Battery ChargersBrand: Pro Useradd a brad Harrison plug between main battery and dual battery , and when bakkie is standing, just unplug brad Harrison and plug the charger into the dual battery.Any thoughts on this?

    Just connect the PSA to the aux battery. Donít bother disconnection the main battery.

    Depending on your system this may keep both batterie nicely charged.

    I drive around 800km per month unless I have a long trip away - so I connect the charger to my aux battery in the engine bay once a month for 24 hours - would this suffice? The rest of the time it's connected to my battery box and keeps the 3rd battery on charge since it's only used for long trips

    Let's see if I have this correct.

    Bakkie - main battery
    Bakkie - Aux battery in engine compartment.
    Bakkie/Storage place - 3rd battery in battery box.

    Where does the battery box live, because we now have effectively two aux battery systems.

    Just a question. Why connect to the aux battery and not the crank battery? I would have thought connecting the charger to the crank battery will charge it first and then the normal dc/dc system will kick in and charge the aux battery as if the power comes from the alternator.

    Prado engine bay - Starter battery
    Prado engine bay - 2nd crank battery with NL solonoid
    Battery box with AGM goes behind the front passanger seat, in the foot-hold. (that is removed from the car and only put in the Prado when I do a long trip) with WRND and takes my solar.

    I got the battery box before I got the Prado - and the Prado came with 2 engine bay batteries. Brand new solonoid and battery, so a waste to remove I imagine.

    so the 2nd battery is the one I charge once a month with the charger- and the question is - is once a month sufficient?

    I have a BX-1 and BX - 2. Have had them for 7 years and they are both in continuous use. BX- 1 on my workbench and the other in my vehicle. The BX - 2 is essentially on all the time as I only use my vehicle for trips and the occasional local trip. Never had a moments hassle

    I have a Benton BX2 connected to my cruiser, at times it stands more than a month, I just connect to main battery and it keeps both main and aux batteries full, never had a problem with the BX2 or BX1 for that matter - BX1 now 10 years old and still going strong

    Dont know why I have a problem then with the BX2's then.
    Bought BX1's from a forum member not too long ago so they are newish and working ok.
    But the BX2's have all packed up.
    Am now trying out my new 20amp Victron blue smart and all is good so far.
