They excel as battery banks in electric boats, as well as for other high-performance battery tasks. Lithium/nickel/cobalt/manganese batteries, used in the Torqeedo outboards, weigh less than lead acid batteries, can be discharged 800 times to 100% depth of discharge, and be recharged in a little over an hour. Your diesel will run for short periods, but with a high load (which it wants).

Or, you can forego a genset and install one or more very high-output alternators-turning your propulsion engine into a high-output charging machine. Instead of installing a 1000Ah battery bank and running your diesel for six hours, you can install a 500Ah TPPL bank and charge more frequently, but faster. These batteries add intriguing options for long distance cruisers. These advantages make them perfect for trolling motors, solar engergy storage or boating where you need lots of reliable power for a long time. Lithium iron phosphate batteries are a great choice for your boat as well as they are lighter than comparable lead-acid batteries, have longer lifespans, provides constant power throughout discharge and are maintenance free. They need carefully regulated smart charging to prevent damage. Gel batteries, because they’re sealed, are manufactured to very high quality standards. The SVR design nearly eliminates gassing, so they are safer to install around people and sensitive electronics (but gel and AGM batteries still need to be vented). A pressure release valve keeps their internal pressure at a slightly positive level, but they can release excess pressure if needed. They self-discharge at only 3% per month, handle the highest number of lifetime charging cycles, and are maintenance free, spill-proof, submersible and leak-proof. Gel Batteries: Sealed Valve-Regulated (SVR) gelled-electrolyte batteries offer advantages over regular flooded batteries. Long life, a low 3% self-discharge rate and outstanding performance make AGM batteries excellent dual-purpose batteries for boaters who require the fastest recharging, quick starting power and reliable deep cycle ability. High-density AGM batteries have lower internal resistance, allowing greater starting power and charge acceptance, up to 40% of the battery’s total capacity, and quicker recharging than other types of deep cycle batteries. In addition to providing equal saturation across the entire surface of the battery’s positive and negative plates, the fibers in the dense glass mats embed themselves into the plates’ surface like reinforcing rods in concrete, providing more plate support and better shock and vibration protection than in conventional batteries. During charging, precision pressure valves allow oxygen produced on the positive plate to migrate to the negative plate and recombine with the hydrogen, producing water. These high-performance styles include gel batteries, Absorbed Glass Mat (AGM) and different chemistries of lithium-ion batteries.ĪGM Batteries: Sealed Valve-Regulated AGM batteries feature fine, highly porous microfiber glass separators compressed tightly between the battery’s positive and negative plates, which are saturated with just enough acid electrolyte to activate the battery. Newer styles of marine batteries are sealed and do not require you to ever add distilled water.
