Why do my house batteries not charge when I run the engine?
They will read very low if no charging voltage is present. The house batteries (as well as chassis batteries) should charge when the engine is running, if not then you should find a fuse in a positive 12 volt feed between them and the alternator.
Why is my laptop battery not charging properly?
Batteries are susceptible to heat, so if your laptop is overheating, that could cause a problem. As the temperature rises, the battery sensor may misfire, telling the system that the battery is either fully charged or missing completely, causing the charging problems.
Is it safe to charge a battery in a closed room?
