Dual Battery System For 98 Discovery

**OldDisco98** · 15th June 2007, 09:14 PM

Guys

I don't get on here this often and no doubt your guys have mulled over this type of question before therefore if any one can direct me to the right thread / direction / pictures / instructions I'd be most grateful.

Currently putting in a dual battery system in the disco 98. yet..... the air pickup pipe is smack in the way of the new battery, what have you guys done to overcome this problem, not looking to put the a snorkel on, have had suggestions of fitting a "pod " type configuration.

Suprislying I noticed a great difference just running without the pickup pipe tested over about known hills etc, the old girl did pretty good, though I not sure if it’s the right thing to do ….??

Any help, direction greatly appreciated.

Thanks

Noel

You don not say if its a diesel or petrol. If a diesel a snorkel will be a must. Your only other option is to run the air box pick up from the back of the air box a la snorkl layout and have it feed in from somewhere else to get cold air.

If its diesel get a snorkel.......... (later)

I have a 94 Tdi and have fitted a second battery. Like you, I was concerned about the restriction that it might cause to the air box but I have noticed no effect on performance at all. A snorkel is a good idea and something I will fit at some stage.

Judging by the air box description, I think he is talking 98 Disco. A 98 Defender does not have this issue as the second battery can go where the original is under the seat. A 98 (I had a 97) has a second battery cradle on the passenger side usually hindered by air box intake from guard and jack/chaocks in there. Remove jack and chocks, reposition air box intake, preferablly with addition of snorkel, make up bracket to move power steering resevoir slightly and a large battery will fit straight in.

I'd figured that too for the same reasons!

a second 12 in battery wont fit under the pas seat in my 98 Defender due to all the air con fuses and wiring etc. just a hassle to shift it all I put mine in an aluminium box in the pas wheel arch

I have one of the last 98 petrol Discos. It has a dual Optima battery instalation and a Mantec snorkel that required some clever thinking to get right.
The trumpet can be removed from the airbox without any issues. IIRC it can be pulled out from the airbox by hand, keep it to one side incase you want to sell the car as standard later.
You'll have to relocate the coil, amp, jack and power steering fluid reservoir. None of the above is difficult and only the PS bottle will need a bracket fabricating. Be sure to keep the coil within reach of the king lead....this way you can use an original LR item without having to find an extra long one.

To get the snorkel to fit is a bit more of a pig though. The new 2nd battery will block the air intake of the box and you'll to go in through the side. I used the under arch air intake from a P38 Rangie and grafted it through the inner wing. The finished job looks like factory and I'm very happy with it.
Pictures can be posted if needed later.

The above may not be true with other brands of snorkel....mines a Mantec one. I don't like the forward facing leech as is Safari etc.

Regards.
