Selecting a waterproof boat battery charger for your boat
Contemporary "smart" charging solutions have simplified the task of maintaining batteries in optimal condition. Our selection includes a range of options such as onboard battery chargers, portable battery chargers, and combination inverter/battery chargers designed to suit boats of various sizes and styles. For detailed information on chargers integrated with power inverters, refer to our comprehensive guide, "West Advisor: Do-it-Yourself - Selecting an Inverter or Inverter/Charger."
What do boat battery charger need?
Deep-cycle marine batteries exhibit optimal performance and longevity when charged in specific stages, following the "Ideal Charge Curve." This charging regimen is endorsed by the majority of marine battery manufacturers. It's important to note that providing exact voltage recommendations comes with two essential considerations: 1) gel batteries have lower charging voltages compared to flooded-type and AGM batteries; 2) the stated voltages are contingent on temperature.
Given the temperature-dependent nature of charging voltages, offering precise recommendations becomes challenging, as these values fluctuate based on the battery's temperature. Typically, boating activities occur within a temperature range of 50°F to 90°F. The voltage values provided in our West Advisors account for this range. In scenarios of elevated temperatures, lower voltages are warranted, while lower temperatures necessitate higher voltages. It's crucial to recognize that the capacity of the battery bank, denoted in amp-hours (C), is a central concept in the following discussion.
What size waterproof boat battery tender do we need?
Determining the appropriate size for your charger hinges on the size and type of your batteries, along with the availability of continuous or intermittent AC power on your boat to operate the charger. Boats that predominantly stay connected to shore power while docked for most of the week necessitate smaller chargers. The charger should have sufficient capacity to handle continuous loads on the battery system, such as DC refrigeration (often a major consumer of battery power) and lights. Additionally, it should provide ample power for float-charging the batteries. A practical guideline is to ensure the amperage is adequate to match the sum of DC loads plus 10 percent of the amp-hour capacity of the batteries.
For boaters engaged in cruising or anchoring out, with intermittent access to shore power, the charger should offer enough capacity to recharge within the available time frame. This entails replacing the power consumed by all DC loads, as mentioned earlier, along with an average charge rate equal to the amp hours required divided by the available hours. It's noteworthy that the maximum amperage batteries can accept during the Bulk Phase of the charging cycle varies based on battery chemistry: flooded batteries can accommodate a charge rate of up to 25 percent of C; gel batteries boast a higher acceptance rate of up to 30 percent; AGM batteries can handle the highest charging amps, potentially reaching 40 percent of C.
How long do marine batteries take to charge?
Suppose you maintain your house bank within the recommended 50 percent to 85 percent state of charge, charging it once daily. In this case, restoring the 35 percent of battery capacity can be achieved by operating an appropriately sized alternator for just over an hour. Deeper discharge levels or smaller alternators may necessitate a longer charging duration. Interestingly, relying on an oversized charger or a colossal alternator to deliver high current can be counterproductive and may lead to a shorter battery life. The excessive current generates heat and causes excessive gassing (the dissociation of electrolyte into hydrogen and oxygen). This eventually triggers the voltage limit, prompting a transition from the Bulk to Acceptance Phase. Opting for increased battery capacity proves to be a more effective solution, potentially reducing the required recharging time. Larger battery banks can accommodate higher charging amps, enabling quicker replenishment and reducing the need for an extended engine run.
Multi-Stage Smart Charging While Underway
In achieving efficient battery charging, a multi-stage intelligent shore power charger forms just one component of the equation. To optimize the effectiveness of your charging system, you require an intelligent voltage regulator and a high-output alternator. In the automotive realm, an alternator's primary role is to maintain a happy starting battery while providing power to the necessary electrical/electronic systems for vehicle operation (such as headlights, CD player, vanity mirror lights). In this context, a basic, internally-regulated alternator generally suffices to fulfill these requirements.
Contrarily, on a boat, the alternator and regulator must support a significantly larger battery capacity to cater to both engine starting and house battery loads. These components must be capable of effective charging at lower rpms and endure harsh marine conditions. Moreover, the alternator and regulator may experience prolonged periods of inactivity, posing one of the most challenging aspects of alternator life. Simultaneously, this system must align with the expectations of boaters who seek to charge their batteries with minimal engine running time.
Advanced voltage regulation is tailored to suit the requirements of modern battery types and accommodates the additional load imposed by contemporary electronics and inverter technology. This intelligent regulation aligns the alternator's output with the specific needs of your batteries (such as AGM, gel, Optima, deep-cycle flooded), enabling faster charging tailored to their unique constructions. This ensures the charging system optimally leverages the enhanced voltage provided by high-output alternators. Regulators like Max Charge and ARS-5 are equipped with customized programs for each battery type—simply specify your battery type, and the regulator takes care of the rest.
Moreover, many intelligent voltage regulators feature the capability to monitor both battery and alternator temperature. They adjust voltage levels accordingly, maximizing safety and performance. If a condition arises that poses a threat to the system or the vessel, the regulator has the capability to cease charging entirely.
