Can these batteries handle offshore conditions?
Reported use includes up to 35 hours in strong offshore currents without recharging. Customers report stable performance under sustained load.
How many days can I get from a 36V 120Ah?
Reported use includes up to 5 full days before recharge depending on conditions. Customers report strong multi-day performance.
How long will a 36V 120Ah run a Garmin Kraken?
Reported use includes 10-hour sessions using approximately 9% capacity. Customers report extended runtime with low discharge.
Build, Compliance & Product
What type of lithium cells are used?
LiFePO₄ prismatic cells correctly rated to deliver true Ah capacity, protected by a BMS and temperature sensors.
Are these batteries Australian made?
Yes. All Green Marine Lithium batteries are Australian Made and tested in Australia.
What makes Green Marine Lithium different?
Certified Australian Made, IP67 waterproof, IEC 62619 compliant, and built to exceed AS/NZS 3001 & 3004 using true-capacity LiFePO₄ cells.
Our batteries are built with correctly rated cells and designed to be serviceable. Imported lithium batteries use undersized cells so you never get the true capacity advertised and they’re throw away items that cannot be recharged or serviced.Are your batteries repairable?
Yes. Unlike imported lithium batteries, our systems are built to be serviceable and repairable in Australia.
All work is subject to assessment under our Return Authorisation process.
Do you offer custom builds?
Yes. We supply standard systems and custom builds for marine, off-grid, transport and emergency applications.

Battery Troubleshooting
My battery has gone flat (over-discharged). What should I do?
If your battery is fully discharged, please contact us with your invoice or proof of purchase and a brief description of the issue.
Lithium batteries are classified as Dangerous Goods and must be packed and transported correctly for any return.
If you would like technical support before arranging a return, email info@greenmarinelithium.com with photos of your battery, installation, wiring, and charging setup.
Assessment timeframes vary. If a battery is found to be non-warranty (including over-discharge), labour and freight charges may apply.
App Troubleshooting
I’m having trouble connecting to the GML App. What should I do?
First check:
- The latest version of the GML BMS App is installed
- Your device is not connected to other Bluetooth devices during setup
If you are still unable to connect, email info@greenmarinelithium.com with:
- Clear photos of the battery in your setup (including wiring and charger)
- A short screen recording showing your connection attempt
Warranty & Returns
Do you replace batteries before testing?
As the manufacturer, our batteries are assessed under our Return Authorisation process before any warranty determination is made.
Why is my battery cutting out early?
Most cases relate to installation, charging, or system setup rather than battery failure. All returned batteries are assessed to determine cause before any outcome is confirmed.
What is not covered under warranty?
Conditions such as over-discharge, incorrect charging, installation faults, or system setup issues are not warranty.
How do I return a battery?
All returns must be approved in advance under a Return Authorisation (RA). Once approved, we arrange compliant Dangerous Goods freight and provide packing instructions.
Will I be charged for a return?
If a battery is found to be non-warranty, labour and Dangerous Goods freight charges may apply.
