Key Advantages over traditional Lead-Acid Batteries:
Voltage remains constant for much longer during discharge.
Much higher charging rate and so faster charging – varies according to the charging system used.
Can be discharged quickly without damaging the cells, making them ideal for use with inverters.
Can be discharged as much as 95% on average without damaging the battery. Thousands of charging cycles compared to just a few hundred from a typical lead-acid battery.
Very low rate of self-discharge means they can be left unattended for months.
Zero maintenance required.
Approximately 40% - 50% lighter than a good quality lead-acid battery with a similar Ah rating.
The ability to charge quickly from the vehicle’s engine can remove the need for a generator or fuel cell.
Can be used in almost every situation where a lead-acid battery is being used to power appliances in a motorhome, campervan or caravan.
