Built for Australian Roads.
Not an Overseas Afterthought.
Most batteries are engineered for European or North American conditions. Salty Cells sodium-ion chemistry thrives in Australian heat, dust, and vibration.
3,000+ Cycle Life
A typical lead-acid battery lasts 300–500 cycles. Salty Cells delivers 3,000+ — that's 6–10× longer before it ever needs replacing.
Loves the Heat
Lead-acid degrades fast above 35°C. Sodium-ion chemistry handles high temperatures without sulphation, swelling, or capacity fade.
True Drop-In Fit
Same BCI group dimensions and terminal layout as your existing battery. No adapters, no extra wiring, no workshop time.
Up to 70% Lighter
At 4.5–7.5 kg versus the 15–25 kg of comparable lead-acid, Salty Cells saves weight without sacrificing cranking power.
No Thermal Runaway
Unlike lithium-ion, sodium-ion is inherently stable. No fire risk, no toxic gas, no exotic cooling requirements.
Cleaner Chemistry
No lead, no sulfuric acid, no cobalt. Sodium-ion is safer to dispose of and kinder on the environment — from production to end of life.

Real reports from owners and engineering press around the world.
A Toyota Tacoma owner in northern Canada reports his sodium-ion starter battery “fires up the truck at full power every time” — at −40°C, with no battery blanket or trickle charger. His verdict: he’d never go back to lead-acid.
— 4WD owner report, chevybolt.org forums
Engineering press on the latest 12V sodium starter batteries: 3,000+ cycle ratings and roughly 8× the service life of lead-acid, with stronger cold-cranking output across −40°C to 60°C.
— Interesting Engineering, 2025
A sodium-ion battery fleet covering 15,000 km across seven months in northern China — including operations at −40°C — retained over 90% capacity throughout, with 20–25 minute charge times even in extreme cold.
