Simple way to reduce battery charger max voltage?
It seems like it''s healthier long-term for the battery to not charge it all the way. Is there an easy way to reduce the max charging voltage (on the dc side, I don''t really want to crack open the charger itself)? I think I want it to stop charging around 35.5V,

12v
Then you should make R>42Ω (12.5V/0.3A). The problem with this approach is that the current drops as the small battery gets charged, what leads to a long charging time. A more sophisticated approach would be to use a low-dropout active current limiter instead Mark Twain''s attempt to "reduce all jokes to a dozen or so primitive kinds"

If V1 (the AC-DC power supply) is ON, then the output of the Charger is connected to the Battery. If V1 is OFF and you are on battery power then G1 is high and G2 is low. With G1 high the output of the Charger is disconnected from the Battery.

How to reduce current? | Electronics Forum (Circuits, Projects and
But basically I cant simply "only" use a resistor to charge a battery. If you have a supply of 14,8V, and limits the current to 171mA (desired current used to charge battery) with only a resistor (86ohm 2.5W) in serie, the voltage drop will be far to big, and will not supply the battery with enough voltage to charge it fully (7.2 needed, at least)

Towards circular battery supply chains: Strategies to reduce
Although current battery recycling enables, in part, the circular flow of materials, it will take several decades to fill this material gap and establish full circular supply chains for battery materials, and therefore, independence from mining (Dunn et al., 2021; Wesselkämper et al., 2024; Xu et al., 2020).

Furthermore, if you want to take better care of your batteries, you can consider adding another set of 5 batteries in parallel to reduce the current load on each individual cell. Having a second set of batteries in parallel will reduce the discharge rate to ~1.2 C, generating less loss due to internal resistance.

How do you reduce amps in a circuit?
A circuit pulls an amount of current from the source. The source does not feed its rated current into the circuit. So you don't need to do anything to 'reduce amps'. When selecting your power source you need the correct voltage and at least the required current. The circuit will only draw as much as it needs. Great thanks.
How do I reduce a battery charge voltage?
Place 4 diodes in series with the 5V output, reducing the charging voltage to 2.4V and add a 2.7V zener diode across the battery pack to prevent the charge voltage increasing above this as the charge current drops towards zero. A series resistor is all you really need, based in what you said.
How do you reduce current in a circuit?
Here are some general techniques: Resistance: Introducing resistors into the circuit can limit the flow of current. The relationship between voltage (V), current (I), and resistance (R) is defined by Ohm's Law (V = IR). By increasing the resistance, you can reduce the current.
How to reduce current in a car battery?
Current can be reduced in a car battery by using a charger with a lower amperage output or by charging the battery for a longer period of time. It is important to ensure that the charging rate is appropriate for the battery being charged to avoid damaging the battery.
How to reduce amperage in electrical systems?
That’s why it is often necessary to limit amperage through various techniques. There are several effective methods to reduce current flow in electrical systems. Let’s examine the main techniques: Since voltage and current are directly proportional (V = I x R), keeping voltage constant via regulation helps control amperage levels.
Does reducing voltage reduce current?
Since current is directly proportional to voltage (I = V/R), reducing the voltage will reduce the current, provided the resistance remains constant. Current Limiting Components: Components like current-limiting diodes or current-limiting resistors can be used to restrict the maximum current flowing through a circuit.
