    Hi I am looking for some advice, I have a Gulfstream friendship rv, it’s very large around size of a large coach and I have 2 battery’s for engine starting and 2 battery’s to run electrical items inside, my starter battery’s are dead and need replaced, I tried using starter/ leisure battery’s but they didn’t last long. Can anyone recommend what battery’s I should use?

    Hello, You obviously know that AGM batteries are very intolerant of anything but the precise charge program and that they like a higher 14.7v charge rate than most chargers can give?
    Did you realise that not one Caravan or Motorhome charger unit currently fitted has an AGM charge profile so that an AGM fitment will result in it being slow to charge, with short life. Especially if the Caravan/Motorhome has one of the common fixed 13.8v chargers?
    We are seeing AGM batteries that have failed and damaged the charger in a very short space of time.
    Websites warn against the fitment of an AGM battery in a van that did not have it as original equipment.
    Around 10% of the failed AGM batteries we have seen have exploded as a result of being charged with a none AGM optimised charger.

    You have not mentioned Elecsol batteries which are in my mind one of the best value units you can buy. I had a 130ah Elecsol battery in my motorhome for 5yrs. I sold the motorhome with the battery performing perfectly well. I used it 50/50 wild camping and on electricity and it never let me down.
    At present I have the same make and capacity of battery which I have used for 3yrs now with no problems.
    Elecsol are slightly more expensive but in this case, you do get what you pay for.
    Aparently the Elecsol battery technology is carbon fibre which maintains its voltage level to a far lower level of discharge, thereby giving you the theoretically capacity of a battery 33% larger.
    I must point out that I have absolutely no connection with Elecsol but am bemused at the fact that they have not previously been mentioned in this article.

      Hi Dave, Elecsol wasn’t one of the batteries we mentioned, but we welcome feedback from readers, so many thanks for the recommendation! If anyone wants further information, please click here.

    I have an 2002 Autosleeper Polensa with a monstrous size battery which is now dead so is it possible to say just what battery I should look for?

    • Lucie @ Caravan Guard says:

      Hi Brian,

      I passed your comment to Auto-Sleeper, they say that any battery size will work on the Polensa but as standard they always fit a 105ah to their models. If you bought the motorhome second-hand, it may be that the previous owner installed a larger battery.

      I hope this helps.

      Many thanks

    Your article does explain some important things, thank you, and although I don’t expect you to recommend one battery manufacturer over another, it would be very helpful to have a list of manufacturers, and the names of their products if different from their trading name, that provide all the information you say we need to make an informed choice rather than leave us to try to find what could be a small needle.

    • Lucie @ Caravan Guard says:

      Hi John,

      Thanks for your comment.

      Which product you choose very much depends on the style of camper you have and your camping lifestyle. Lots of wild camping requires a better battery. Motorhomes with compressor fridges and diesel heaters require much more Ah capacity and more durable batteries.

      There are hundreds of different leisure batteries of various sizes and durability, dimensions and terminals available, and all with Life Cycle figures for 50% DOD published or provided in writing by the purveyors.

      For example picking a typical 100ish ampere hour battery, Platinum/Oldham/Tungstone/Crompton brands with Marine plus, Leisure plus, Leisure plus sealed, are all quoted at 120 cycles.

      • Platinum AGM and Pro-Golf quote 500 cycles.
      • Trojan Deep cycle 27TMH-AP quote 600 cycles.
      • Trojan Gel 31GEL-UT is 1000 cycles
      • Trojan AGM 31AGMOD-ST is 1000 cycles
      • Trojan Deep Cycle Industrial claim 2800 cycles
      • Banner on request via their web site provided figures for their products as well
      • Banner Energy Bull claim 270 cycles
      • Banner Running Bull AGM claim 360 cycles
      • Banner Traction Bull Block GEL claim 900 cycles
      • Sonnenschein GEL GF 12 105 V claim 1100 cycles
      • Sonnenschein GEL GF 12 094 Y claim 720 cycles
      • EXIDE DUAL Marine claim 280 cycles
      • EXIDE DUAL AGM Marine claim 750
      • EXIDE EQUIPMENT GEL claim 910 cycles
      • NDS =GREEN POWER AGM claim 500 cycles.

      It’s important to carefully measure up the space you have to ensure that the chosen battery will fit. Always ensure that battery fumes have an escape path to the outside, frequently using a little pipe connected to the battery gassing manifold and fed through a hole in the floor. And secure batteries properly so that they cannot become dislodged in the event of a vehicle roll over.

      Many thanks

        Thank you for your reply, yes, I should have stated what sort of situation I would be using a battery. I can only have a non gasing type because the battery is under the passengers seat in my motor home with no venting to the outside and I prefer wild camping so it must take deep cycles (?). kind regards

    After having many disappointments when caravan nine with poor battery life,I have used a big,heavy forklift truck battery for 6yrs now with my MOTORHOME.No problems whatsoever but found it best to restrict TV usage when wilding.

  8. Dave says:

    Have you considered offering a discount on Motorhome Insurance if a Dash Cam is fitted and operating at all times when driving.?

    • Lucie @ Caravan Guard says:

      Hi Dave, we have yes. It’s one of the safety and security devices we may look to offer a discount on in the future.
      We’ll keep you posted on the blog with any latest developments.

      Many thanks
