Trying to charge multiple batteries simultaneously with an individual phone chrgr, allows you to apply all the benefits associated with a modern Nitecore Q2 charger maintainer to each battery based on the own needs. This is likely to prolong the life of each battery and save you money in the long term.
Today’s onboard multiple-bank chargers are smart chargers with built-in microprocessors to control their multi-phase charging and maintenance processes and may also include desulfation and recover functions. They can deliver better electric battery performance and longer life. They are also likely to allow you to maintain all of your batteries through the off-season unwatched automatically so that your boat is ready when you are in the Spring.
How much power do you need? The output you need from a multi-bank system is closely related to the application of each battery. Here’s a quick guide to amperage result for some applications:
u Low Output – (6 amps or below) A low output model may be applicable for maintenance use or any low amp hour battery application.
u Medium Output – (9 – 15 amps) The medium output model would be applicable for medium use or occasional use perhaps is without a doubt weekends for a trolling motor.
o High Output – (15 amps or above) The high output model would be used in high amp hour battery apps (150 Ah for example), or any situation where repeated rapid recharging is required.
Be aware when choosing the amperage output based on its description. Vendors and manufacturers usually post amperage in two ways. One way is to distribute the total amps by multiplying the output of each bank times the amount of banks. For example, they might publish the output as 40 Amps, but what they are really telling you is that the charger produces 10 Amps output for every bank. The other way and more useful is to publish the output each bank.
A common quick calculation to find out how much amperage output you need is to determine the amp-hour rating of each battery through adding them with each other. Then multiply that quantity by 10% to get the amperage needed. Regarding four 105 amp-hour electric batteries, you would need approximately 10% of 420 amp-hours or 42 amps or about 10 amps for each bank for a 4-bank battery-charger.
Most marine systems depend on 12V or 12-VOLT batteries. Make sure the onboard battery charging system you choose can manage your boat’s battery voltages.
Marine batteries serve various purposes on-board your motorboat starting from starting to providing electricity for all the primary systems. You are likely to face deep cycle, Solution Cel, or AGM battery packs in a marine environment.
Gel Cel batteries require a special charging profile that can easily be provided by models specifically designed to charge Gel cel batteries. Onboard battery rechargers that charge AGM or deep cycle batteries by yourself are not equipped effectively charge Gel Cel batteries. Make sure you choose a marine model that can handle all the battery types you have.
Most modern multi-bank onboard system have integrated microprocessors. These computers run clever programs to charge and maintain your batteries unattended without overcharging or damaging your batteries, charger or vessel systems.
Many include pre-installed safety features that protect against reverse polarity and can also monitor battery pack charging status, battery express, and adapt charger output to match the needs of each individual battery.
