ABS stands for antilock braking system, and if the ABS warning light is illuminated in your car's gauge cluster, that means the antilock system has been deactivated because of a malfunction. Your car's regular brakes should work fine, but the antilock feature that prevents wheels from locking up during braking will not work. In addition, if your vehicle has stability control and traction control, those will be disabled as well because those systems rely on the same wheel-speed sensors as the antilock system.
All batteries, even those using gel instead of electrolyte lose charging capacity as the time passes. The reason for this is that the chemical breakdown of the connections inevitably takes place leading to the deterioration of the plates and loss of the electrolyte. When your vehicle has start up or charging problems, the vehicle troubleshooting procedure should start with a test of the battery. You do that with a visual check followed by a voltage test. If the battery is ok, other components of the electrical system is probably the reason, but battery problems are by far the most likely reason.
