Issues to Contemplate Earlier than Shopping for a Marine Battery

Electrical engineers could have designed immediately’s top-quality batteries, however you don’t need to have a level to slender down your decisions. Listed here are a number of the facets of marine batteries patrons want to concentrate to earlier than pulling out the billfold and making a pricey mistake.

Development

For many years producers had been content material with the usual flooded cell battery. Sealed batteries supplied an enchancment over the originals, however it wasn’t till latest forays into electrical automobile design that battery producers got the inducement to develop batteries that had been lighter, held a cost sooner and lasted for hundreds of discharges.

  • Flooded Lead Acid: The essential battery your father in all probability utilized in his automotive, boat, and every thing in between, flooded lead acid batteries have lead plates suspended in sulfuric acid that retailer and discharge electrical energy. Their easy development makes them the least costly choice for marine batteries, they usually have a tendency to carry up for 2 to 3 years earlier than needing to get replaced. Homeowners of those batteries ought to periodically test the extent of the acid within the battery, as it could actually evaporate out throughout charging, leaving the lead plates dry. This damages the battery, making it much less environment friendly, and finally nugatory.
  • Absorbed Glass Mat (AGM): One step above the flooded cells, AGM batteries nonetheless use acid and result in react and retailer electrical energy. However the acid contained in these cells is soaked into fiberglas mats to stop it from sloshing round or evaporating when the battery is being recharged. These batteries are inclined to final barely longer than flooded cells, however their fundamental benefit is that they require no upkeep.
  • Lithium Iron Phosphate: The newest expertise for the trendy boat, Lithium iron phosphate batteries have many benefits over flooded lead acid and AGM batteries, equivalent to sooner recharge instances, much less weight, and for much longer lifespans. These big-time advantages, nonetheless, include a big-time price ticket, typically costing as a lot as 4 or 5 comparably sized normal batteries.

Capability

For many boating functions, capability will be measured in certainly one of two readings, relying upon the aim of the battery.

For beginning batteries, it’s all about instantaneous output, which is measured as Chilly Cranking Amps (CCA). So long as the beginning battery meets the CCA requirement of your outboard, it should carry out as wanted till it must be changed. There’s actually no have to spend extra cash on greater CCA batteries than what your outboard wants.

For dual-purpose and deep-cycle batteries, a battery’s amp hours can provide an excellent indication of its reserve. Whereas amp hours are literally a measure of how a lot cost goes into the battery throughout charging, it gives a relative quantity to check batteries of various sizes and kinds. For many trolling motors, batteries of 80- to 100-amp hours will present a full eight-hour day of use beneath regular situations. Preventing excessive winds and present can deplete batteries faster, slicing that utilization significantly.
