A larger 40A DC-DC charger is better when: You need the extra charge quickly during the ''bulk stage'' of the charge, despite the battery not reaching full capacity. You have a large battery bank where the ''absorption stage'' is comparatively short to the ''bulk stage'' of the recharge process.
Customer ServiceWhen the battery status is normal, the current is charged to 10.0V at 3C current, and then the constant voltage is charged to the current of 0.01C. Observe the appearance of the battery changes. After the battery is charged, measure the initial state of the battery and discharge it to 0 V at 0.5C when the battery status is normal.

Customer ServiceThe 40A charger could have a current draw on the alternator of 60A. This is less than the total remaining capacity of the alternator (75 amps) during start-up. The 20A charger could have a current draw on the alternator of 30A, so it would put little stress on the alternator.. Alternatively, the 60A charger could have a current draw of 90A, so it would exceed the maximum capacity

Customer ServiceDepending what type of 48v battery it is, you will probably be charging at around 55-56 volts. At 20 amps that is 1.12 kW. But the battery charger is not going to be 100% efficient. Depending on what type of charger you buy, the efficiency might be say 70% to 85% as a guess. So required input power to your charger might be 1.6 kW to 1.31 kW.
Customer ServiceHowever, the battery management system must still monitor the temperature of the battery and shut it down should any conditions that could damage the battery occur. Some of these conditions include high or low voltage, high current, short circuit, and over temperature. Barring any other conditions, if you don''t exceed the maximum continuous

Customer ServiceIs a Battery AC Or DC Current? Most batteries produce direct current (DC). A few types of batteries, such as those used in some hybrid and electric vehicles, can produce alternating current (AC). Batteries produce DC because the chemical reaction that generates electricity inside the battery only flows in one direction.
Customer ServiceThe recommended charging current (thus, the battery charger size) for lead-acid batteries ranges from 0.1C to 0.25C (10% to 25% of the battery''s Ah rating). For example, if your lead-acid battery has 100Ah of

Customer ServiceCharging Time (h) = Battery Capacity (Ah) / Charging Current (A) Example 1: Using a 40A charger to charge a 120Ah LiFePO4 (approximately 0.3C charging C-rate) would take around 3 hours ("around" because this is only an estimation): Charging Time (h) = 120 Ah / 40 A = 3 hours. Example 2: Using a 10A charger to charge a 100Ah AGM battery would take

Customer ServiceThe recommended charging current (thus, the battery charger size) for lead-acid batteries ranges from 0.1C to 0.25C (10% to 25% of the battery''s Ah rating). For example, if your lead-acid battery has 100Ah of capacity, you should use a charger rated for at least 10A (or anything between the 10A to 25A range).

Customer ServiceShort-circuit current of a new alkaline AA battery is in the low amperes. About 3A for a fresh Kirkland AA cell. 2.4A for a Panasonic Platinum power. Source: actual measurements
Customer ServiceThe battery capacity, or the amount of energy a battery can hold, can be measured with a battery analyzer. (See BU-909: Battery Test Equipment) The analyzer discharges the battery at a calibrated current while measuring the time until the end-of-discharge voltage is reached. For lead acid, the end-of-discharge is typically 1.75V/cell, for NiCd
Customer ServiceIn your battery example, there is no return current path so no current will flow. There is obviously a more deep physics reason for why this works but as the question asked for a simple answer I''ll skip the math, google Maxwell''s Equations and how they are used in the derivation of Kirchhoff''s voltage law. Batteries do make a good example for this simply
Customer ServiceFactors like battery type, capacity, and state of charge influence how much current is needed to charge a 12V battery. Generally, the charging current for a 12V battery is around 10% of the battery''s capacity. Charging

Customer Service$begingroup$ So in other words, as the cell in the parallel bank approaches total charge depletion, it would not affect the bank V when it is 100% depleted,but it would eventually cause that bank to be depleted sooner than the other banks in the battery. When the charge of that bank is depleted, it will output less V & cause the battery to have a lower V
Customer ServiceThankfully, the NLDC-40 and NLDC-25 both support Lithium-ion and LiFeP04 batteries, as well as regular Flooded, Gel, AGM and Calcium batteries. So, from that perspective, using a 40A charger is noticeably beneficial if your driving habits are typically around the 3-hour mark or less. Beyond that, the two products start to offer similar results.
That said, although the 40A DC-DC system appears to be the “silver bullet” of vehicle-based, auxiliary-battery power, the benefit of using a 40A charger is only noticeable during the ‘bulk’ stage of recharging. Once you include the ‘absorption’ stage in the overall process, the total recharge time is similar for both products.
The amount of current in a battery depends on the type of battery, its size, and its age. A AA battery typically has about 2.5 amps of current, while a 9-volt battery has about 8.4 amps of current. Batteries produce direct current (DC). The electrons flow in one direction around a circuit.
To do a rough calculation take the panel wattage and divide by the nominal voltage, 400W ÷12V = 33.3A, in reality it will likely be around 25A therefore a 40A controller would be a good fit, but pay attention to the final paragraph.
The batteries say they have a maximum charging current of 37.5A, which I imagine i want to get as close to as possible in order to charge the battery as quickly as possible, but looking at descriptions of charge controllers it seems that they are rated more based on the amperage input (which i think would be 8A in my case - 400W/24V...).
It can supply 1.5 V, but I don't see any information about the current (in A) or the power (in W). Where can I find this information? You should look in the datasheet of that AA battery and check the discharge curves. That gives you an indication. Note that the highest discharge current that is mentioned is 1000 mA = 1 A.
