The proven benefits of Blue Star Technology now enhanced to deliver extended battery life in partial state of charge applications perfect for marine use.

In marine applications using the main engine, gensets, or solar power for charging, batteries experience frequent recharge cyling which severely shortens their service life.
To minimize the impact of frequent charging, it is crucial to recharge batteries as quickly as possible. At the same time, the cyclability of the battery needs to be exceptional, as the number of charging cycles will be greatly increased when the grid goes down or you need to shut your genset down before the batteries are fully charged.

NorthStar Blue+ batteries recharge five times faster, and can handle three times as many charge cycles as standard AGMs - thanks to their PSOC capability.
Most standard batteries are not partial state of charge (PSOC) capable, and require a full recharge after each discharge to achieve long life. Performing a full recharge of a battery takes a significant amount of time, as achieving the last 20% of charge takes almost as long as the first 80%.
A PSOC capable battery does not require a full recharge every cycle and is therefore much faster and easier to recharge. In unstable, or off grid applications, such as using diesel gensets, frequent discharge and recharging will quickly kill standard batteries, but NorthStar Blue+ Batteries will deliver exceptional performance in this type of application, and ensure the user of a longer life, more reliable battery power supply, while reducing the overall cost of batteries.

Blue+ advanced AGM (Absorbed Glass Mat) construction means all the acid electrolyte is absorbed in fiberglass matting between the lead plates.
There is no electrolyte to leak (even if the case is broken), no water levels to check, and no corrosion to clean.
The flexible AGM construction allows for installation in any orientation, except inverted.
AGM batteries also have a very low self-discharge rate, so they can be stored for much longer periods without requiring a re-charge than standard batteries.

NorthStar Blue+ batteries are among those most commonly selected for critical telecom industry back-up power supplies - where cycling abuse is high, and reliability is absolutely crucial.
