LandCruiser 79 Series Dual Battery: 200Ah Behind The Seat
There's no good spot for a second battery in a 79. The tray's for work, the engine bay is full, and anything in the cab eats the only space you've got for gear. The Custom Lithium 79 Series battery uses the dead space behind the seats — it's an all-in-one unit shaped to the back wall of a dual cab, so there's no tray, no fabrication and no fighting for room. Available in 200Ah or 230Ah, Australian-made, and it suits both facelift and pre-facelift dual cabs.

Why The LandCruiser 79 Series Dual Battery May Be Right For You
- It uses space you weren't using anyway — behind the seats is dead air in a 79 dual cab, so you get serious capacity without surrendering tray space or the back seat.
- No tray, no fabrication — the all-in-one case is designed to the vehicle, so it's a bolt-in rather than a weekend of measuring, cutting and swearing.
- Real capacity for long trips — 200Ah or 230Ah is enough to run a fridge, lights, a water pump and an inverter for days between charges, which is what a 79 tends to get used for.
- It fits old and new — both facelift and pre-facelift dual cabs are covered, so it suits a late model or something that's already done a few hundred thousand.
- It's made here and supported here — Australian-Made certified, built for the conditions these things actually work in.

Before You Order
Installation is straightforward but may require drilling and nutserts in the back wall of the cab. It suits dual cab variants only, and it may not work with aftermarket child seat anchor points — worth checking before you order if you've got those fitted. Call us on 1300 902 361 if you're unsure.
LandCruiser 79 Series Dual Battery FAQs
Should I get the 200Ah or the 230Ah?
They're the same physical install, so it comes down to how long you stay out. 200Ah suits most touring setups running a fridge, lights and charging. The extra 30Ah is cheap insurance if you're running an inverter, a second fridge or a diesel heater, or you park up for several days without driving to recharge.
Can I install this myself?
Custom Lithium recommend installation by a qualified auto electrician, and so do we. These are vehicle-specific kits rather than a battery in a box — there's high-current wiring, fusing and a DC-DC charger to get right, and getting it wrong is an insurance problem rather than an inconvenience. Depending on the vehicle there may also be minor trimming or drilling involved.
Is the wiring kit included?
No. The battery is the all-in-one unit here — the wiring kit, DC-DC charger, monitor and mounting brackets are separate. Not everything shown in the photos is supplied. Give us a ring on 1300 902 361 and we'll work out exactly what you need for your setup rather than guessing.
Do I need a battery tray?
No. That's the point of a vehicle-specific battery — the case itself is shaped to the space it mounts in, so there's no separate tray, no fabrication and no hunting for a flat spot. It's why these fit where a standard rectangular battery won't.
Where are they made?
Australia. Custom Lithium's auxiliary battery systems are Australian-Made certified, so parts, support and warranty all sit here rather than at the end of a long email chain overseas.
