There are two processes where the battery resistance will change.

a) The normal operation of charging a battery will increase it's resistance, whilst removing sulfation, and the resistance will drop as sulfation occurs. This follows the formula that V=I × R.

With a constant current (I) the battery charges the voltage (V) rises. Is simple terms as an equation must balance then if one side increases then so must the other. So if V rises then I × R must also rise and of I is constant then R must rise. The reverse is the case when the battery discharges.b) Although sulfation and de-sulfation are the normal reactions in a lead acid battery sulfation can become ingrained and not subject to being processed by normal charging. In this case the battery appears charged and has a high resistance. To overcome this, or at least to try to, a high voltage can be applied in an attempt to force the sulfate to return to the electrolyte.

A lead acid battery will have a ration of sulfuric acid and water as the electrolyte. The process of charging forces any sulfate from the battery plates back to the electrolyte which increases it's specific gravity. The specific gravity of pure water is set at 1. By dissolving substances in water makes if heavier per volume. The common amount of acid brings electrolyte specific gravity (SG) to 1.128 approx.

Measuring the SG with a hydrometer can show if the acid is in the plates and they are sulphated.

The two times this would occur is a) in the normal process of discharging and b) in the longer term build up of sulphated plates that do not respond to a normal charge and the battery is termed 'sulphated'

The SG will also vary on the level of electrolyte as the water evaporates. As water evaporates the SG increase along with ration of acid to water. Adding water will lower the SG and show the battery is not as fully charged as it may seemed when the electrolyte was lower than the designed level.
