![]() Your alternator should be capable of delivering rated output equal to the maximum acceptance rate of your house battery bank. They need to be charged by a large case or extra large case alternator to produce enough charging current, due to their nearly unlimited appetite for amps. Gel batteries can accept 30 percent, AGM batteries can accept 40 to 50 percent, and newer technologies like lithium ion or TPPL (thin plate pure lead, such as Optima) can accept even more. High output alternators like this extra Large Frame Balmar 98-Series Alternator delivers current similar to some gensets, with up to 5kW of output.Ī standard flooded battery, of either the starting or deep cycle type, can accept charging current equal to 25 percent of its available capacity. ![]() The Acceptance Rate of the battery-what percentage of its total amp hour capacity it can accept-is different for some battery chemistries. Battery ChemistryĮach type of marine battery-flooded starting battery, deep cycle flooded battery, gel or Absorbed Glass Mat (AGM) battery-has its own unique charging characteristic, which affects the type and size of alternator you’ll need to charge it efficiently. Selection criteria you should consider include the following. Charging systems vary by type of boat, as well as a collection of other variables including engine type, engine room space, belt type and size, battery bank size and battery chemistry. What to Consider Before You Buyīefore you invest in a high-output charging system, save yourself a lot of trouble and dollars by ensuring that you buy the correct system for your application. This article will help you make the right choices when shopping for a high-capacity alternator, such as one of the models from Balmar-boating's premier manufacturer of marine alternators and charging system upgrades. Upgrade to your charging system: If you want to replace your automobile-style alternator with a larger, high-capacity model that can charge more batteries, charge larger batteries and bring them up to charge more rapidly, you are also at the right place. Here at West Marine we often see customers looking for an alternator for two reasons.ĭirect replacement: Do you need a direct replacement for a factory installed automotive-type OEM alternator? Good news! Our aftermarket parts supplier Sierra offers automotive-style alternators for most common marine engines. Performs above 40 ☌įorced cooling by fan operation of the pulley provides a lot of power in higher temperatures, especially close to the engine.Automotive-style alternators, like this 68-amp Delco-style three-wire model from Sierra, are internally regulated. The 12/130 and 24/75 models are also available with a multigroove pulley. The Mastervolt Alpha alternator is specifically designed for powerful charging, even with a low engine rpm. Standard alternators only supply the specified capacity at a high rpm. ![]() Some engine brands come with Mastervolt alternator brackets as an option. For all engine typesĪlpha alternators are equipped with several fixations for customised alternator brackets, available from your installer or engine supplier. TIP: A second alternator on the main engine, combined with a larger battery bank and inverter, could be an alternative for a generator. Using a Battery Mate or battery isolator in conjunction with an Alpha alternator makes it possible to easily charge two or three separate battery sets simultaneously.
