    Hi Guys

    A little confused could you help please.

    Am I being naive by asking this question?
    I was under the impression that when driving the leisure battery is being charged once the starter battery is full.
    Am I wrong? Do I need to hook up every few days to charge the battery?
    If so do I need to install an intelligent charger so that the alternator will charge the leisure battery and keep the charging of both batteries topped up.

    What are any implications to adding another battery or batteries.
    I have an Autocruise Starblazer XL with a 110amh battery I was going to replace this and buy 2 new 110amh batteries for a good battery bank so if I'm wildcamping I would have the freedom to stay away for 4/5 days without hookup.

    Yes I know one good battery will last a while!!

    Thanks in advance.

    Gary

    Am I wrong? Do I need to hook up every few days to charge the battery? no, there are many alternatives, drive (Alternator), solar, wind, generator
    If so do I need to install an intelligent charger so that the alternator will charge the leisure battery and keep the charging of both batteries topped up. the alternator will only charge 1 battery at a time, regardless, you will need an isolating switch which basically switches the charging current /cycle from 1 battery to another, or an automatic charging relay, this is still the same, it only detects when one battery is charged and then switches to the other

    What are any implications to adding another battery or batteries. none, unless you are trying to charge them together? but the above still applies, and be sure you go + to + and - to - otherwise you will have 24 volts and become a lorry!!! connecting live battery to dead battery is simple other than you need a jump lead to connect the live battery to the dead battery, easier than disconnecting and reconnecting, expecially in the dark, when 'I see dead people' are out, whooahhhhhhhh
    I have an Autocruise Starblazer XL with a 110amh battery I was going to replace this and buy 2 new 110amh batteries for a good battery bank so if I'm wildcamping I would have the freedom to stay away for 4/5 days without hookup. what are you powering up? wattage? search on the forum, for usage etc, from what I learnt in 1 week, using standard items, fridge, lights, TV, hot water etc, you will get about 6 hours max on a battery with 120amp, to recharge said battery, you need to keep moving, or install a solar panel etc?

    that's my quick intake on understanding, now for the barrage of corrections, and then I will learn something else Gaz:thumb:

    Hi, firstly you need to check if your lb is getting charged from the engine :Smile: if not the simplest way is to fit a relay to charge it when engine runs.Engine on and alternator runs switches relay on charging lb :Smile: Adding another lb will double your off grid time.
    I only have 1 x 110amphr lb but this lasts 3 to 4 days easy :thumb: everything 12v inc tv/dvd etc.If you find you are running low a trip to shops etc, tops up the battery:BigGrin: edit forgot to say relay costs aprox a tenner
