Frequently Asked Questions


What batteries can be used?

It will charge most types of rechargeable 12V lead-acid type battery / Lithium LiFePO4 Battery 60 Ahr capacity up to 140Ahr. There are four main types of 12V lead acid battery - conventional wet lead-acid battery, calcium,lithium  AGM and gel. It can charge both cold cranking type car batteries and deep cycle batteries.

How do I charge?


Please refer to content ‘Getting Charged’ in the photos provided 

Is it waterproof?

No, care should be taken to shield it from direct sunlight and the elements.

How do I know if the battery is fully charged?

The Battery Level Icon is solid and not flashing, battery will is fully charged.

Can I leave the Ultimate-800 continually plugged in?

Yes, it will keep on float cycle. Usage is plug-and-play. The built-in battery management system prevents over-charging and over-discharging of batteries. The USB output will only supply the amount of power.



12V 100Ah Lithium Ion Battery LiFePO4 Deep Cycle Recycle Camping RV 4WD Solar

Lithium batteries provide far greater useable amp hours than their lead-acid counterparts. Unlike lead-acid,lithium batteries can be deeply discharged without affecting the cycle life. This means you can use the battery for longer before having to recharge. In comparison, AGM batteries are generally recommended to only be discharged to 50% of their capacity to maximize their cycle life whereas lithium can generally be discharged to 80-90% of the capacity.
