100 series TD cranking battery

1,i was told by toyota warranty would be void if any related problems arose due to only one crank battery regardless of capacity?so i stayed safe and installed 3rd tray with gel cell to drive fridge etc and replaced both mains with optimas and in 3 years no problems.cheers Paul

I have split my batteries with OL dual battery system , put in athe largest cranking Battery I could get , works fine

Mate of mine did this a couple of years ago and still going fine..

Obviously the surf is a little different to the 100 series, however the 3.0LTD's came standard with two cranking batteries. I split the batteries and put a 700CCA overlander as the start and it works great. (better than the other two crappy ones).

Hi

I have a 2003 TD 100 series and the second change made was to separate the batteries with a Redarc and ran this setup with the standard batteries for 12 months. Since changed to a 600 or 700 cca starting battery and a 600cca marine accessories battery, both from Century.

Many trips and never a problem - run usual bits, compressor, Engle, UHF, lights etc...

Note that if a sparkie does the work it may be same cost to go to ARB and fit 3rd battery tray & kit (fitted the tray but compressor sits in it).

HI # 1

No problem with the set up. The factory batteries are quite small and one replaced a with decent ones and a Redarc or ABR isolator fitted there is no problem.

I am currently designing the 3rd battery and fuel filter assembly for the LC and should be ready soon.

Regards Derek.

Did it on my mates 100 series and works a treat. Went for a big N70zz cranking batt and it starts the engine without a wimper. He has an deep cycle AGM wired up in the second battery position which works perfectly as his camping battery.
I personally cannot see the point in fitting a third battery.
(Standard cruiser batteries are about the same as a Falcon battery.)

78/79 series with the (almost) same 1HD-FTE engine use a single N70 size battery. Mine starts fine at zero degrees.

Member No 1, I put a Rotronics system in shortly after I purchased my 100 Series TD. I replaced the OE batteries 18 months ago with Champion/Exide Extreme 620CCA12V N70EXL for cranking and Champion/Exide Endurance 12V 75A/H ED5 for auxillary. ($125/$135) I never really had any problems with the OE and no problems with the replacements.
