    Dual Battery Volt Issue

    Howdy,

    I bought a Traxide dual battery DT90 and fitted it 1 year ago. I bought 2x Exide Orbital 34DC AGM battery's which only have 50 AH each. I have been noticing that the auxiliary battery has not been lasting as long as it did 1 year ago. I bought the 2 battery's brand new at the same time 1 year ago as well.

    I had the battery's tested today by Battery World and they told me that the cranking and the aux battery are only holding 12.40 volts each I am really only using the aux battery for a fridge when camping at this stage. Best I can work out it uses 4.5 amps. When not camping, the aux battery is not connected to the fridge or anything else and left connected to the cranking battery. With only 12.40 volts, I am not getting the fully use of the battery.

    Do you think the battery's could be faulty at all? They were on sale for $250 each when I picked them up. I am yet to call the shop I bought them from but do you think it is a battery fault and worth asking for replacements under warranty or is it likely that the 12.40 volts were caused by me and not a battery fault?

    I did ask Battery World and the said that as the CCA is fine it was doubtful that I could claim under warranty. I would hope they are telling the complete truth and not just saying that in the hopes I buy new battery's through them.... I would have thought the the battery's might have lasted a bit longer than 1 year?

    So, I am seeking a second opinion. What are your thoughts?

    Hi Scotty, are you driving much and when you drive, is it short or long drives?

    Usually short trips, about 15 minutes around town. I live too close to work! about once a week I will do a 40 minute drive each way. In about 1 month my drive time will go up to 30 minutes drive to work and 30 back. Defender is my daily drive.

    Too many short drive I suspect.

    try putting a battery charger on every night for a week and see if this recovers you batteries.

    My defer doesn’t get garages, I found a decent sized solar panel on the roof really helps.

    Yeah same here. Defender is too big to fit into the garage at home. I would like a permanent fixed solar on the roof and I think it may be my next buy. I have a folding one but it would likely get stolen where I live.....

    Hi again Scotty and solar charging is always better than anything else.


    For just keeping your batteries topped up and in good condition, you do not need a large solar panel.


    A 10w panel mounted inside next to a window, will easily look after your batteries.


    You just need to remember to park in a direction that allows the panel to face the sun.
