New TDV6 battery?

[John_D4]

My 5 or 6yo RAA battery is on the way out. Which battery are people using as a replacement?

This will just wind up another favourites thread. I'll start :

I like Supercharge MF88H.

If the OP did a search on here,all will be revealed.[biggrin]

Previously I had a silver one but couldn’t afford a silver one this time, so I went with boring black. Black seems to work just as well as silver to my surprise.

The OP didn’t think of that…sorry [emoji20]

I did and no disrespect to Brad and his choice but I went with the SSB SS88Ti. It went in today.

About how much?

Keep the receipt, I've had a couple under warranty

Lots because of where I live.

4WD Extreme on eBay will send to you.

Always do keep my invoices. See what happens over the next three years...

Any thoughts on using lithium as a starting battery?

(Obviously you’d need a dcdc and a triggering solenoid which all makes it sound too hard.)

Hi John and unfortunately, you can not use a lithium battery as a cranking battery in any vehicle, not just Land Rovers, with SMART alternators.

There is a lot of outright B/S being used to con people into fitting lithium cranking batteries in any vehicle.

If you own a current Australian Spec Toyota, because they do not have SMART alternators, you can use lithium cranking batteries.

But just about every other make is now using SMART alternators.

I can give you more specific info on this subject if you require it.


Now to your setup. Correct me if I am wrong but I think you want to have a lithium cranking battery that is charged via a DC/DC while the motor is running but is linked to the starter motor just long enough for when you start your motor.

There are a number of problems with this.

First and foremost, you must NEVER run an alternator without having a battery connected to it.

The alternator not only charges the battery but it uses the battery as a massive spike suppressor and if you take the battery out of the circuit while the alternator is running, you can damage quite a bit of your vehicle’s electronics and in the old days, you could even damage the alternators rectifier.

Next, even if you could run the alternator without a battery, and only use the battery to start your motor, you would need a massive solenoid to be able to get enough current to start the motor. For example, have a look at the size of the starter motor solenoid on your vehicle.

Thanks Tim, that all makes sense. A friend mentioned Lithium to me not long ago, but it sounds like it’s but for me.

I think that I’ve settled on the SSB SS88TI as my starting battery.

Not like a magneto (or is it a generator I forget) on a motorbike, I had one that'd occasionally blow the main fuse and just keep running headlights and everything else, I wouldn't even know till I switched it off and tried to restart it.
