    Default Replacement auxiliary battery

    Hi guys

    After my previous escapade with the Ranger's auxiliary battery being kaput, I think it's best to replace it altogether.
    The battery won't be put to hard use, maybe a total of 20 days or so a year - only to keep the fridge running at night/ when the bakkie isn't running.

    The trick is however, the Ranger's battery box can only fit an 84Ah (max) battery - the battery box is about 280mm in length. So this limits me to smaller batteries.
    What battery would be a good one to look at?

    Hi there.

    Yes if anyone can give a simple answer to this seemingly very complicated and perhaps controversial topic, that would be great. Also planning installing a second battery in Prado 150 engine bay.

    Lusted for a Landy but the Pajero was sexier and bigger in the right departments, just like my Missus.

    Most of these list are overseas and don't list vehicles like the Ranger, BT-50 etc. Also the older batteries jumped from 276 to the next size of 314mm. Best to contact a place like Battery Centre for the code. My list indicates the maximum as 75Ah for size 276.

    Another list indicates a 659PP but that battery is 314mm long.

    No problems. Frontrunner makes the bracket, it fits in behind the driver side headlight. An 80 AH Deltec fits in there or a Discover 105 AH battery.

    We used a C-tek charger but there are other options.

    The Ranger is an XL-Plus, so it comes factory fitted with the auxiliary battery, with a switching solenoid to charge it with.
    That's precisely the problem why the battery box only supports ~280mm - being a factory thing. I checked now and it comes out with an 80Ah.

    If there is space, get a bracket made for maybe a 105ah battery.

    Alternatively, you can:

    1. Move the battery to the back with the necessary cables/battery box etc. using the same charging system, cables should be thick enough to counter voltage drop because of the distance.

    2. Move the battery to the back and get a DC-DC/solar controller system. Now you can add solar panels.

    3. Keep the smaller battery up front and add a bigger battery in the back with a DC-DC/solar controller system. Now you can add solar panels. Best for peace of mind.

    Thank you DC Polokwane.
    It's for my dad's bakkie, so I am just trying to get it working acceptably without incurring too much of a cost for him.
    I got a quote from batteriesonline now.... Varta Deep Cycle - AGM - 85Ah - 2 Year Warranty @ R4780. <-- ouch.

    I am looking for a Ranger for myself now and will do the #2 for myself then.

    I have seen that a lot of the blokes in Austria put their second batteries behind their rear seats, Patriot Campers (Australia) built an overland Ranger and they show the battery and charging system. Could be something for you to look at for the Ranger as it tickled my interest. IF you want to watch the build process it is interesting or just forward to 18:26 where they show the battery system (see the link below).

    Coincidentally I've recently found and started watching all of Patriot Campers' videos... they've got some great content.
