A Smarter, Greener Alternative to Conventional Batteries

At HighFlow Energy we believe the future of mobility is about more than getting from A to B – it’s about doing so safely, sustainably and with confidence in your energy source.

Traditional starter and auxiliary batteries – whether conventional flooded or so-called “enhanced” chemistries – come with limitations: shorter lifespans, higher warranty costs, and an ongoing environmental burden from toxic lead and acid. As vehicles become more demanding, with advanced start-stop systems, power-hungry electronics and urban drive cycles, the shortcomings of old chemistries are increasingly clear.

Our SodiumSafe range is designed as a true next-generation replacement. Built on sodium-ion technology, these batteries are engineered to deliver:

  • Longer service life – thousands of cycles in demanding conditions
  • Fast recharge capability – 80% charge in minutes, not hours
  • Extreme temperature resilience – reliable from -40 °C to +85 °C
  • Higher cranking power (CCA) – for modern start-stop and high-load vehicles
  • Low self-discharge – holds charge longer during storage or infrequent use
  • Sustainability edge – no toxic lead or acid, fully recyclable materials

Available in the world’s most common case sizes – DIN, JIS and BCI – our portfolio covers more than 80% of the passenger, light commercial, RV and marine markets across Australia and New Zealand. From a compact hatchback in the suburbs to a 4×4 in the outback, a caravan on the highway or a boat at the marina, SodiumSafe is a drop-in upgrade that combines safety, durability, and sustainability at parity pricing with AGM and EFB.

SodiumSafe FAQs

What vehicles are SodiumSafe batteries compatible with?
SodiumSafe batteries are designed as direct replacements for most modern cars, SUVs, 4×4s, light commercial vehicles, and many RV and marine applications. We supply the most common DIN, JIS, and BCI sizes used in Australia and New Zealand.
Are SodiumSafe batteries a direct swap for AGM or EFB?
Yes — they are “like-for-like” replacements. SodiumSafe fits standard battery trays, connects to existing cables, and is compatible with advanced start-stop systems.
How long do SodiumSafe batteries last compared to lead-acid?
Where AGM or EFB batteries typically last 2–4 years, SodiumSafe delivers a significantly longer service life, with significantly more charge/discharge cycles, higher CCA and lower self discharge rtes. This reduces replacements and lowers lifetime cost.
Are SodiumSafe batteries safe?
Absolutely. Unlike lead-acid or lithium-ion, SodiumSafe contains no toxic lead, no acid, and no risk of thermal runaway. Each battery undergoes independent testing (UL, IEC/AS, UN 38.3) for safety, transport, and performance compliance.
What about recycling and sustainability?
SodiumSafe batteries are built with safe, recyclable materials and contain no hazardous lead or acid. They align with Australia’s Battery Stewardship Scheme and global ESG standards.
Where can I buy SodiumSafe batteries?
We supply container-scale volumes to distributors, retailers, motoring clubs and fleet operators. For individual replacement, ask your local service centre or retailer about SodiumSafe availability.
