Pre-Charge Resistor
The pre-charge current dissipates power in the resistor. Each successive pre-charge adds more power so if the resistor has not cooled between operations then the temperature will rise. Frequent pre-charge operations will cause the temperature of the resistor to increase, potentially to the point where the resistor overheats and fails.

Resistors in Parallel and Series
1. Series resistances add together to get the equivalent resistance: 2. The same current flows through each resistor in series. 3. Individual resistors in series do not get the total source voltage, but divide it. The total potential drop across a series configuration of resistors is equal to the sum of the potential drops across each resistor.
A series battery of six lead accumulators, each of emf 2.0V and
Six lead-acid type of secondary cells each of EMF 3 V and internal resistance 0.30 Ω are joined in series in the same direction to provide a supply to a resistance of 10 Ω. What is the potential drop across the external resistor?
Current limiting resistor for battery charger?
The biggest problem is that I need to limit the current right down to 0.4 amps. I''ve seen several articles on the internet that say: R=(9.5v-6v)/0.4A, which would give an 8.75Ω resistor, or roughly a 10Ω one. This would mean I get 0.4 amps only when the battery voltage is 6 volts (BATTERY DEAD!) and about 0.225A as the battery gets full!!!

Battery model LTSpice
I am trying to create a battery model in LTSpice. The battery model is comprised of a voltage source and a series resistance. However, I need the voltage source to change as the amount of charge in the battery changes (the differential of the charge = current out of the battery). In addition, the resistance needs to be a function of the current.
Current limiting resistor in SLA battery charge circuit?
Your basic assumptions are correct. The problem is as the battery charges the voltage across the resistor will drop and therefore the current will go down. This means that initially the battery starts out charging quickly and eventually reduces to a very small charge. This is not a good approach for a battery that is used all the time.
