    Please can I ask your advise reagrding leisure batteries. First of all are they all one size, or can you get bigger ones? In our motorhome ( autotrail ), there are 2 batteries in the compartment, does that mean we have 2 leisure batteries working at the same time , they are connected together. We are finding that the leisure battery is draining really quick , so thinking it or they have had their day and need replacing. A bit confused with it all. Need your valuable help. Cheers

    Your battery charger will determine the size of leisure batteries you can have as it will have a maximum charge capability. Remember if you change your leisure batteries that they can come in different physical sizes, so make sure you buy the rightvsize for the compartment. Lastly, leisure batteries are different to starting batteries as they run a deep cycle with a slow steady output, starting batteries give short sharp boosts of power (cranking amps) to get things started such as big diesel engines.

    There are places that will analyse you batteries before you waste money, as you could have another problem. Good luck!

    Buy yourself a cheap multimeter for around £10 average - you will use it again at some point, so well worth the investment! - and check that the charger is working. You do this by putting the meter across the terminals and measuring the voltage when the battery is standing, and when the battery is being charged.

    Chances are the batteries are old and suffering from a dead cell or two - again, you can remove the batteries and test for this. You need them charged up firstly, then put the meter across - leave the meter on for a few minutes - and if they are failing, you will notice the voltage dropping off rapidly....and this whilst just powering a meter will prove beyond doubt that is is dead.

    Watch battery branding - many leisures are made by the same company, and are rebadged by wholesalers...also many 'smaller power' batteries, are actually bigger ones, as it is now deemed cheaper to make. Bit of a minefield, but you will get through it easy enough.

    Don't forget to take your old ones to the scrap recycling yard, as they will give you a tenner a pop! Hey! It's twenty pounds off the new ones!!:thumb:

    Stage 1: Have you, can you check the fluid level in the batteries ?
    Stage 2: Are the connections nice and clean with no sign of corrosion ?
    Stage 3: Measure battery voltage on charge, needs about 14.5V

    Then you can consider replacement.
