Thread: Battery failure!! After 13 months!!

I hate to say it, but your new one will probably last less than 12 months. 13.9 volts is not enough, needs to be between 14.2 and 14.4! Check this link out.

I also noted the battery terminals are the same as the ones I've had to replace on my Rangie. Tightened as much as possible and I could still move the positive one.

First thing I do when I buy a P38 is ADD an aditional earth lead from the alternator braket to the chassis and an another power lead from the alternator output direct to the battery positive.

that's a really interesting link ytt105. I'll be doing some tests to check out mine tonight.
Its probably been discussed before somewhere, however, can anyone "highly" recommend a certain battery for a P38?

Had exactly the same problem with my Nissan Patrol (now gone thank god). The alternator went while it was still under warranty. So they fixed the alternator and fitetd a brand new Century battery. 14 months later the new battery dropped a cell and it was out of warranty. Maybe it's something with the manufacture of Century batteries?

Yep, I almost know the RR.net electrical sticky by heart I should have said that the 13.9 was at idle, and with the broken battery. Broken batteries cause a load. It is 14.2 this morning at idle with the new battery.

Thanks. I have become increasingly suspicious about these dinosaurs. They are really getting tarnished and assuming that process is also going on on the inside, its time to replace. This is an area we shouldnt skimp on.

Me too. The blue lead in the pic is an additional big earth from neg batt to alternator/block mount. My RR already has a direct connection from Alt to Batt pos - where did your original charging cable go via?

I fitted ADDITIONAL leads to both negative and positive. Leave the originals there, after cleaning all the contacts of course.

14.2 is good, but still do all the test in the link.

Yes, additional. I mentioned that I added an additional cable in the previous post. The original remains. I will be upgrading the original charging cable with a significantly larger gauge and replacing the aging terminals before they cause additional problems.

Hi Glen
Supercharge batteries at Willawong have a good range and provide a hefty AULRO discount...well they did 12m ago!!
cheers

The optima yellow top batteries is another one. I bought one about six month ago and have been really happy with the performance. If you can stretch the budget a little, they're worth every penny. Not only are they a cranking battery, but a deep cycle one too, no maintenance required, so no notorious acid spills when off roading. Plus they're vibration resistant.
