Just doing preliminary investigation on the new Prado diesel.

I want to put a 120a Fullriver AGM battery in the back and enquire if anyone else has sited a battery in the back of a Prado.
If so would appreciate details.

Have been informed a 90a AGM will fit under bonnet but prefer the 120a which has served me well in the past.
Had it fitted on top of wheel arch in the old 80 series I had.

Hi Pedro

Here is a picture of the 'FLYER' in a 120 Prado. The Fullriver 120 a/h unit should fit into the 'FLYER' as the case size is quite small. HGL12012A 331x175x239. Your other option is a MRV70 mounted under the bonnet. 105 a/h with 760cca.

Regards

Derek.

Derek,

I'd just like to take this opportunity to give you a pat on the back for your input.

The number of times you get on here to provide some useful info "without" resorting to stuffing your product down the proverbial is really refreshing.

A breath of fresh air methinks, which reminds me that I must pump up the tyres and bugger off into the bush this WE.

Regards

I am now thinking of putting 2nd battery under bonnet.
Derek mentioned an alternative to an AGM for under bonnet but I would prefer an AGM.

Has anyone fitted an AGM larger than 90a under bonnet, or know what size the cradle from Toyota will take?

Hi Peter

Prado's are high up on the list of dynamically unstable vehicles, so I would be cautious about putting any heavy extra load outboard of the axles as it increases their tendency to rollover.

Robin,
Thanks for your input.
Not quite with your statement re "outboard".
Are you saying a second battery in back of Prado ,should be approached with caution, or a second battery anywhere same approach?
I had a 2nd battery in back of 80 series but it was over wheel arch .

If Toyota fit the second battery cradle under bonnet I would think it would be safe in spot selected.
Your further thoughts would be appreciated.

Hi Pedro

4wds tend to tip over more easily than most cars because they are higher and have higher centre of gravity.

This effect is most often noticed when under brakes and turning.

The back of the car tends to rise and swing out leading to an early rollover
in extreme cases.

Any heavy load in the back makes the effect worse, so its best
to leave the very back of the car for light stuff like sleeping bags etc.

Prado's aren't as good as Patrols and Cruisers etc in this respect.

The effect is much less if the weight is put more in the centre of the car,
I.E. between the front and rear axles.

In some catergories of vehicles, like small buses, well documented court
cases have resulted in passengers no longer being allowed to sit more
towards the back than the line of the rear axle.
