How to Measure Internal Resistance of a Battery
A commonly encountered school-level Physics practical is the determination of the internal resistance of a battery - typically an AA or D cell. Typically this is based around a simple model of such a cell as a source emf in series with a small resistor. The cell is connected to a resistive load and (in the simplest case where load resistance is known) only open circuit

6 FAQs about [Causes of lead-acid battery experiment errors]
Why are lead-acid batteries so bad?
In other words, they have a large power-to-weight ratio. Another serious demerit of lead-acid batteries is a rela- tively short life-time. The main reason for the deteriora- tion has been said to be the softening of the positive elec- trodes.
What causes a battery to be contaminated?
Contamination in sealed and VRLA batteries usually originates from the factory when the battery is being produced. In flooded lead-acid batteries, contamination can result from accumulated dirt on top of the battery and when the battery is being watered. Watering the battery with tap water has a serious consequence on the battery.
Can lead acid batteries be recovered from sulfation?
The recovery of lead acid batteries from sulfation has been demonstrated by using several additives proposed by the authors et al. From electrochemical investigation, it was found that one of the main effects of additives is increasing the hydrogen overvoltage on the negative electrodes of the batteries.
Are additives a good index of deterioration of a lead-acid battery?
Several kinds of additives have been tested for commercially available lead-acid batteries. The increase in the internal resistance of the lead-acid battery during charge-discharge cycles coincided with a decrease in the discharge capacity of the tested battery, so the internal resistance can be a good index of deterioration of the battery.
What are the effects of additives on lead-acid batteries?
From electrochemical investigation, it was found that one of the main effects of additives is increasing the hydrogen overvoltage on the negative electrodes of the batteries. Several kinds of additives have been tested for commercially available lead-acid batteries.
How to maintain a lead-acid battery?
As routine maintenance, you should always check the battery electrolyte levels and ensure that the battery cells are always covered. Sealed and valve-regulated lead-acid batteries are designed in such a way that the gases released from the electrolysis of water in the electrolyte, recombine back to form water. 3. Thermal Runaway
