Marine Batteries
Tips & Advice to help you make your decision on Marine Batteries
When boats are a primary component of your business, it is important that you have the right marine batteries to keep them going. Figuring out which batteries to purchase can be difficult, though, because they come in a variety of styles.
Some batteries are designed for cranking engines while others are built for trolling motors. Consult the manufacturer of your boat or engine for recommendations. A battery's ratings for marine cranking amps and reserve capacity are noted on the label, so you can easily identify which batteries meet your engine's specifications. A dual-purpose battery can handle both; however, it may not be as durable or powerful as a battery built specifically for your needs.
Review the differences in conducting materials as well. Gel batteries are typically low-maintenance and long-lasting, but they are also pricier and difficult to charge with standard chargers. Wet-cell batteries cost less, but they require routine maintenance and are slightly less durable than gel batteries. Another option is an AGM battery. These batteries cost more than wet-cell batteries, but they are durable and do not require maintenance.
Prior to purchasing marine batteries, find out if the distributor offers warranties and maintenance and repair services. Compare the costs between distributors as well. For more information on choosing and purchasing batteries, visit the links at Business.com.
Marine Batteries
Choose the right technology and configuration to get the most from your boat batteryBy J. Simonetta If you run a charter service or other boating business, batteries are usually the only source of electricity available once you leave the dock. In general terms, batteries used to start the boat are "regular" batteries; the same ones used to start cars every day. It's the deep cycle marine batteries that you can discharge deeply and recharge without ill effects, which power lights and on-board electronics, that require thoughtful consideration prior to purchase.
Deep cycle batteries are all lead-based, but there are 3 main types of lead-acid batteries: flooded acid, gel cells and Absorbed Glass Mat (AGM). The most common type, flooded acid batteries, aren't sealed so care must be taken that the liquid electrolyte inside doesn't spill out; they also require maintenance to replenish the electrolyte inside from time to time. Flooded acid batteries come in the most sizes and are typically the cheapest option. Gel cells, the next step up, contain a thickening agent so that the electrolyte solution can't slosh around. The gel also prevents leakage should the battery case crack. Absorbed Glass Mat (AGM) batteries are the most recent advance in marine batteries. They're the most expensive, but they're the most impact and vibration resistant and offer other advantages including fast charge dispensation. Here are a few things to consider:
1. Analyze your boat battery applications and capacity needs.
2. Gather information on marine batteries and consider marine lead acid batteries and gel boat batteries, based on your specific application.
3. Comparison shop for the best deal.
Analyze your daily usage, determine size and capacity
The rule of thumb for deep cycle marine batteries is to have about 4 times your daily energy requirement. Other variables, such as your battery technology, charging system, available space and usage may argue for either a weaker or more robust marine battery system. Get boat batteries appropriate for your application: to start engines or to power equipment for hours.

Compare marine lead acid batteries vs. gel boat batteries, based on your specific needs
Determine which technology--flooded acid, gelled acid or Absorbed Glass Mat (AGM)--is best for your budget and usage profile. If the batteries are going into the bilge, you'll want gel or AGM batteries: both can operate under water, oriented in any direction. It's also important to research the advantages and disadvantages of hooking up batteries in series or in parallel.

Now it's time to buy a boat battery. Obviously, batteries are heavy, so shipping 100 lbs. of batteries halfway across the country may not be cheaper than buying locally. It's still a good place to find marine batteries for sale, however, as it allows you to comparison shop websites offering wholesale marine batteries and local merchants in your area. Compare statistics such as reserve minutes, battery capacity and longevity.
