Most modern multi-bank airborne systems have integrated microprocessors. These computers run smart programs that charge and maintain the battery unattended without overcharging or damaging the battery, charger, or marine system.
Many products have built-in safety features that prevent reverse polarity, and also monitor the battery's charge status, battery status, and adjust the charger output to suit the needs of each battery.
Harsh marine environment
The marine environment is a humid environment, including direct spray and moisture. Even if your model may not be exposed to direct spray, any charger you are considering using should be completely sealed, waterproof, and able to withstand harsh marine environments.
Depending on where you plan to install the in-vehicle system, it can be affected by everything from salt spray to heavier seawater or freshwater splashes. In any case, you can count on continuous erosion from corrosion.
When a battery charger is almost always characterized as an on-board model, it will have mounting capabilities and associated hardware that comes with it. Installing a battery charger will make the installation cleaner and reduce the risk of damaging the battery charger or its cable.
It is worth noting that this is not always the case, so if you are considering mounting it on a bulkhead, it is worth checking the included hardware and mounting brackets.
Ships with enclosed engine compartments may accumulate fumes from batteries and fuel, and if not ventilated, may pose a fire and explosion hazard. Any onboard battery charger you choose should comply with ISO 8846 and US Coast Guard Title 33 CFR 183.410 ignition protection specifications, which states compatible equipment:
o Does not ignite combustible hydrocarbon mixtures around equipment when ignition source causes internal explosion
o Failure to release enough electrical or thermal energy to ignite a hydrocarbon mixture
o or ignition source is sealed.
Also look for other safety features, including overvoltage, overload, overheating and reverse polarity protection.
Some multi-cell battery chargers have integrated AC power sockets to support other onboard AC devices near the charger. If this is the feature you need, check it.
With all other things being equal, a good determinant may be the tiebreaker. Considering the harsh environment that marine battery chargers endure, the risk of failure is real.
Manufacturers who provide long-term warranty tell you that they are confident in materials and workmanship. You should look for a model with at least a 2-year limited warranty.
For serious sailors who need its convenience and performance, multi-bank installable battery chargers are their universal choice. The right multi-bank onboard battery charger can meet all your marine battery charging needs.
