Think of the battery as a bucket full of water. Small holes in the bucket drain the water. A garden
hose is used to fill the bucket back up (while the water is still draining out).
Your alternator (garden hose) is not supplying electricity to the battery (bucket of water) and your
accessories (holes in bucket) are draining the battery.
Yes, the battery needs to be fully charged & load tested to verify that it is still ok. A battery older than
5-6 years, is usually on its way out anyways. But most likely you have an Alternator issue.
