Equipped with anti-explosion technology which improves safety and sealed terminals assuring no electrolyte leakage.
FLC
SERIES
Better Partial State-of-Charge Performance, more Cycles, and Higher Efficiency
Our FLC Series Lead-Carbon batteries are an advanced VRLA lead acid battery which use a common
lead positive plate (anode) and a carbon composite negative plate (cathode). The carbon acts as a sort of
'supercapacitor' which allows faster charging and discharging, plus prolonged life at partial state of
charge.
The negative plates of these batteries are made from lead and carbon and thus combine the advantages
of normal lead-acid batteries with those of a supercapacitor. The addition of carbon ensures that these
batteries have a higher charge acceptance and therefore have to charge for less time than regular
lead-acid batteries. Moreover, they provide more power and are more resistant to (extremely) low
temperatures.
By adding Lead (pb) to the negative plate there is also less resistance resulting in a longer life. In addition,
this latest technology suppresses sulphation better than any other technology.
