Frequently Asked Questions

Are Lithiumax batteries a direct replacement for my lead-acid or AGM battery?

In most cases, yes. Simply check the Ah rating and CCA or CA rating of your OEM or existing battery and compare it to the Ah and CA rating or the Lithiumax battery that is specified for your engine size and use i.e. as a daily driver or as a race car, with battery isolator switch. For road going or daily driven vehicles you may require a set of SAE terminal posts for your battery to allow the factory terminal loops to be fitted. The standard vehicle charging system or alternator will charge the Lithiumax battery as per the standard OEM or factory battery, no changes required at all though some modern vehicles require the battery to be registered with the ECU. This may not always be the case, however consult your service agent for confirmation or to complete this simple task, as with all new batteries fitted.

The Lithiumax battery specified has a lower Ah rating to the OEM battery, is this ok?

There may be a variation in the Ah rating of the Lithiumax battery when compared to the OEM unit. In most cases this is ok and the Lithiumax battery still provides a reasonable capacity or reserve. Lithiumax batteries have been designed to be the ideal compromise between capacity/power and ultimate light weight performance.

What size battery does my vehicle require?

That depends on the engine capacity and the required current needed by the starter motor when cranking the engine. As well as the vehicle/boat use for Ah requirements. A reference guide is available on the Lithiumax User Instructions PDF available on the Support page as well as in the description of each Lithiumax battery in the Shop on this website.

Is the Lithiumax battery suitable for vehicles fitted with Start/Stop functionality?

Yes, Lithiumax batteries are ideal for vehicles fitted with start-stop systems. In fact lithium is superior for this application due to its high relative starting current capability as well as superior charge/discharge cycling versus lead-acid or AGM/Gel batteries.

I've heard the stories about lithium catching on fire?

Not Lithiumax! Our batteries utilise the highly stable LiFePO4 type, Lithium Ferrous Phosphate battery chemistry that is rigourously tested by DEKRA Germany to comply with the very stringent UN38.3 safety standards. This means Lithiumax batteries are very safe, non toxic 100% organic and stable. Unlike the acid filled lead-acid or AGM batteries they replace.

Do I need a special charger for a Lithiumax battery?

No, the alternator will charge your Lithiumax battery just like the lead-acid or AGM unit at 14.4V. No trickle charging required, unless the car, bike, aircraft or boat has a system drain when parked up, as per any battery type, trickle or maintenance charging may be required in this case. Lithiumax batteries don't lose charge easily by sitting unused like lead-acid or AGM batteries do. Any trickle or maintenance charge is suitable as long as it doesn't utilise a lead-acid battery conditioning or desulphation process. If a multi battery charger, use the Lithium sertting or if it doesn't have one then the AGM/Gel setting can be used.

What if I don't have low volt protection fitted to my vehicle and I accidentally drained the battery?

There are a number of Lithiumax battery models that now come with low-voltage cut-out technology built-in with a simple battery 'restart' button. In these cases should the Lithiumax battery be drained to the point where it cuts out, simply press the 'restart' button and you may, depending on circumstances, still have enough energy in the battery to start the engine. If not then simply recharge the battery and it will return to normal operation.` For Lithiumax models without the 'restart' feature, it depends on how low and for how long the battery was below 8V. It could be recoverable with a dedicated Lithium charger (e.g. Noco Genius range). Below 8V is not ideal, and may void the warranty. So best to monitor the vehicle's drain initially over a period of time to understand the system drain on the battery. Ideally charge the battery if it falls below 12.8V.

How can such a small battery run my lights, stereo, etc?

The simple answer is It doesn't, the alternator provides the power for those while the engine is running. If the engine is off, it then comes down to the Ah rating of the battery as to how long these ancilliaries operate for on battery power alone.

How long will these Lithiumax batteries last compared to lead-acid or AGM?

If correctly maintained, your Lithiumax battery will outlive lead-acid or AGM batteries at least 4 to 1, that's 4 times longer life. In most cases your Lithiumax battery will be the only battery you will ever require for your vehicle.

What is the Warranty on Lithiumax Batteries?

Each Lithiumax battery is covered by a 2 year factory warranty. If correctly maintained however, your Lithiumax battery should last for 7-10 or more years.

My car is a Porsche, Mercedes, BMW, Lotus, Jaguar, Audi, Ferrari, Mini, Corvette, Mustang, Lamborghini, Honda, Toyota etc. Do you have a battery for all of these?

Yes. A reference guide is available on the Lithiumax User Instructions PDF on our Support page. You'll also find guidance in the Shop section under each battery model as to their application. With Lithiumax batteries, the specification is determined by the engine capacity of your vehicle. Supporting accessories such as mounting plates, brackets and SAE terminals can also be purchased through our shop to make fitting your ultra-light Lithiumax battery simple and easy.

Is Lithiumax also suitable for Motorcycles, ATV, Jetskis, Go-carts, Boats and Aircraft?

Absolutely, we have a specific model for Motorcycles, ATVs, Jetskis & Go-carts that delivers a whopping 300CA and weighs just 0.8kg. For Boats and Aircraft, simply follow the engine capacity guidlines as per motor vehicles found on the instructions within our Support section or within the model specifications within our Shop

What about those batteries that claim to use prismatic cells & therefore superior?

This is old information that has long past its relevance. The cell types used are specific to the application and one technology is not in any way superior to another, it comes down to packaging in many cases. What you need to avoid is cheaper Li-Po (Lithium Polymer) chemistry which is far more unstable than the LiFePO4 chemistry used exclusively in Lithiumax batteries. We use both cylindrical and prismatic cells in our batteries and the only difference is the application packaging restrictions where one type offers different packaging and size options. There are no other advantages to either cell type.
