Stormline Batteries

100 % maintenance-free.
Very low discharge cycle : less than 3 % per month.
Low gas emission in normal conditions of use and in a ventilated environment, never exceeding 4% critical concentration (threshold when oxy-hydrogen becomes explosive).
No leaks or spills of acid.
Can be installed in any orientation (except upside down).
Discharge level : 80 %
Charge voltage : 13.7 V without boost / 14.5 V with boost.
100 % sealed technology (VLRA : Valve Regulated Lead Acid) adapted to intensive cycles : 1000 cycles for 50 % discharge, 500 cycles for 80 % discharge.
It is usually considered that a 12 V battery is discharged when it reaches 11.8 V when not in use.
This battery features very thick plates as in industry applications and will provide top performance in all marine circumstances.
