Amptron Marine Lithium Batteries
Australian brand, wide format range. Manufacturer specifications — not independently bench-tested.

Amptron battery suitability and support
The retrofit answer. Slimline and low-profile cases that fit compartments other brands cannot, with datasheets that vary in quality between generations.
The most common practical problem in a lithium retrofit is not price or capacity, it is that the new battery does not fit the space the old one left. Amptron's range of slimline and low-profile cases solves that more often than anyone else's, which is why it appears in our verdicts as the awkward-compartment pick.
Documentation depth can vary between product generations. Ask for the exact model's full datasheet before you commit, and if your installer needs particular evidence for the job, obtain it in writing first.
Boat Battery has not published an independent bench file for Amptron. Until one exists, treat every specification figure as a manufacturer claim.

What we like
- Case formats that fit compartments other brands do not
- Wide range across capacities
- Reasonable pricing in the middle band
Where it falls short
- Datasheet quality varies between product generations
- Not independently bench-tested by us
- Small dealer base; mostly direct
Best suited to
Retrofits where the battery compartment dictates the case.
Look elsewhere if
Your installer needs a complete, consistent datasheet to certify against.
Amptron battery capacities and model checks
Use these voltage and capacity profiles to prepare a shortlist. Ask the supplier for the exact model code, current datasheet, permitted marine application, charge and discharge limits, dimensions and warranty terms. A brand-level comparison does not establish that every model is suitable for the same boat.
Compare alternatives at the same voltage and usable energy. A 24V 100Ah battery stores about twice the nominal energy of a 12V 100Ah battery and is not a direct replacement for a 12V bank.
