In my boat, I have had a couple of lead-acid batteries fail with a shorted cell. In one case, the shorting may have been caused by the impact of a minor collision, but the batteries were 6 years old, so reaching end-of-life anyway. The shorted cell reduced the battery voltage by 2 volts, and apparently had enough internal resistance to prevent ...
lead acid
If a current is being drawn from a battery or recharged into a battery, then its internal resistance causes the terminal voltage to be lower (or higher) than its open-circuit/no-load voltage. There''s also the ''refractory period'' after drawing a load from the battery, where after you stop drawing, you''ll see a ''recovery'' of terminal voltage (it''s all in the chemicals). In the case of …
