The battery has reached the end of its life
In South African conditions a starter battery typically gives three to five years. Heat is harder on a battery than cold is, and Gauteng summers are hard on them. Past that, internal resistance rises and the battery stops accepting a full charge.
A conductance test shows this clearly, which is why we test before we sell.
The alternator is not charging properly
If the charging system is under-delivering, the battery never gets back what the starter took out. Every trip leaves it slightly flatter than the last until one morning there is nothing left. A new battery in that car will do exactly the same thing.
Something is drawing current with the car switched off
Alarms, trackers, dash cameras, aftermarket radios and boot lights that never go out all pull current overnight. A parasitic draw large enough to flatten a healthy battery in a few days is common on cars with accessories added later.
The car is not driven far enough
Short trips can use more charge starting the car than the alternator puts back before you switch off. A car used for ten-minute school runs and nothing else will slowly discharge even with a good battery and a good alternator.
