Power tech motormover

[Redlac]

Hi all
Just purchased an elddis aurora van fitted with the above motor mover, I took my leisure battery from my old van and fitted it to this one, It was showing 12.2volts so had a problem with the motor mover cutting out. I recharged the battery and it was reading 12.8volts, Imoved the van about 3 yards and noticed the voltage dropped again to 12.2 volts, would this indicate the battery is faulty now. Also I have purchased a new 70ah leisure battery recommended for the van (not fitted yet) but have read I need a 110ah one. Can anyone shed any light on this for me.
Thank You

If you have mover fitted 110 amp is the one as mover pull voltage down quite a bit.

Did you mean Powertouch motor mover?
If so the manual for mine says:
'A 110-Ampere hour battery is recommended for optimum operation of the Powrtouch Evolution. Smaller batteries may be utilised but mover performance may be reduced.'
I can confirm that mine works OK with a 78ah car battery.

How quickly after coming off charge did the battery show 12.8v? To get an accurate reading it needs to be off charge for at LEAST 30 minutes before taking a reading
Was that voltage on the caravans built in meter, or a multi-meter. Caravan meters are notoriously inaccurate.
Try it with your brand new battery, it will be more than enough unless you have to use your mover for an inordinately long distance.
If it works fine then your old battery is clearly "an ex battery, its has ceased to be, it is no more, it's dead mate!"

I've used a 70Ah car battery on my 1200kg van to move it 30m up the driveway which is sloped at 25% in places. It had no problems.

Provided you always use the EHU when on site ( and at home before you leave) that should keep the battery (70 or 110Ah ) fully charged, and that should not cause any problems with the mover.

We always use a 110Ah for our motor mover on our last caravan with no problems

Given you have 70AH battery I suggest use it and see how it performances. You won't break anything.
