Deep cycle flooded batteries, such as Rolls, like to be slow charged (10% of Ah capacity), so if your alternator is large, then it may make sense to have a smaller 120V charger for good deep 10% of Ah capacity charges of your thick plate Rolls or industrial type 6V or 2V bank. Sizing can be a personal preference often based on how quickly you desire to replenish the bank but do keep in mind heat and charger longevity. Need more current? You can go to three or more. In bulk mode, which is what youвЂ™d be doing with genset charging, both chargers will be pumping out their maximum current to the bank and youвЂ™ll get through bulk pretty quickly. Using two separate chargers will give you the added benefit of a back up if the other charger fails.

For larger chargers Victron & Mastervolt make good ones, or you can simply double up on the Sterling Pro Charge UltraвЂ™s.

On vessels with large banks or AGM or other types of batteries that have high acceptance rates, a 60A charger can limit your recharge times when using a gen set to charge while away from the dock. My one and only real gripe with the Sterling chargers is the largest single charger is 60A.

Size carefully and donвЂ™t forget to consider the dockside DC consumption.Д¬onversely if you power your charger off a generator, when away from the dock, as many boaters do, you will want as much charger as your batteries will accept to keep generator run times as short as possible. In this case you would need a 30A charger to maintain a charge rate of 10% of Ah capacity. This results in a charge rate of just 5% of of the banks Ah capacity. For example a 10A dock-side load, with a 20A charger, means that 10A is feeding your DC loads and the remaining 10A is going into the bank for charging.ДЄ 20A charger with a 10A dockside load means the battery charger, sized at 10% of bank Ah capacity, is really only supplying 50% of its potential output for charging. Your dockside DC loads reduce the amount of current the charger can supply for battery charging. are all taking charging potential away from the charger in order to run. On-board items such as DC lighting, DC refrigeration, computers, TVвЂ™s stereo etc. However, what if your on-board loads are consuming 10A? When dockside, DC devices can consume power and rob it from what your charger can feed the bank. A 200Ah house bank would suggest a 20A charger is necessary for a 10% of Ah capacity charge rate. You should always consider the DC dockside loads when trying to get to your minimum 10% sized charger.ДЇor instance some power boats & sailboats have small banks, lets call it a 200Ah bank. If you choose to size on the low side, at 10% of Ah capacity, you should also consider any DC loads your boat will use while at the dock. The charger can always be larger and this will allow for faster charging. You can always choose to charge at a lower rate, but you are giving up cycle life by doing so. The ProCharge Ultra can be run in parallel to achieve the minimum charge current guidance for batteries such as these. If you had four of these, for a 400Ah bank, youвЂ™d need 160A of charging to meet OdysseyвЂ™s вЂњminimumвЂќ recommended charger guidance. The image below is for a single Group 31 Odyssey TPPL AGM battery.

Ignoring minimum charging amperage guidance will mean that youвЂ™ll not get the optimum cycle life out of the bank. This high current charging is beneficial to these batteries and leads to increased cycle-life.

Lifeline AGMвЂ™s have a minimum recomendation of 20% of installed Ah capacity. Batteries such as Odyssey TPPL AGMвЂ™s, Northstar TPPL AGMвЂ™s & Firefly Carbon Foam all benefit from high current charging (40% of installed Ah capacity is advised). When sizing a charger it is always important to pay attention to minimum charger sizing recommendations. Pay Attention to Your Battery Manufacturers Suggested Charging Guidance! Sizing on the larger side, for faster charging, should take into account the battery type you are charging eg: GEL, AGM or Flooded. Sizing at 10% of Ah capacity of course assumes you have the time needed to charge at 10% of Ah capacity and no other loads while charging. A 400Ah battery bank, sized at 10%, would get a 40A charger. The general consensus, & industry recommendation, is to size a hard wired charger for a minimum of 10% of the banks rated Ah capacity, for flooded deep cycle batteries. This is a decision that is entirely up to the user, with some caveats.
