Drop-in replacement for your 12V lead-acid battery — sodium-ion technology. No rewiring, no modifications. 5,000+ cycles, 40% lighter, zero maintenance.
🔍 Find the Right Battery for Your Car
Most batteries are engineered for European or North American conditions. Salty Cells sodium-ion chemistry thrives in Australian heat, dust, and vibration.
A typical lead-acid battery lasts 300–500 cycles. Salty Cells delivers over 5,000 — that's more than 10× longer before it ever needs replacing.
Lead-acid degrades fast above 35°C. Sodium-ion chemistry handles high temperatures without sulphation, swelling, or capacity fade.
Same BCI group dimensions and terminal layout as your existing battery. No adapters, no extra wiring, no workshop time.
At 5–10 kg versus the 15–25 kg of comparable lead-acid, Salty Cells saves weight without sacrificing cranking power.
Unlike lithium-ion, sodium-ion is inherently stable. No fire risk, no toxic gas, no exotic cooling requirements.
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.

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.
