Battery Drains Quickly After Short Drives

Some Santro drivers notice that the battery loses charge even after short city drives of 10–15 minutes. The battery may need repeated jump-starts, and accessories like lights and wipers seem weaker than normal. What factors can cause rapid battery drainage in a Hyundai Santro, and what steps should be taken to fix o r prevent it?

Possible Causes:

Weak alternator not fully charging battery during short trips

Parasitic drain from aftermarket accessories like stereo, alarm, o r dash cameras

Old o r sulfated battery losing capacity

Loose o r corroded wiring between alternator and battery

Solutions:

Measure charging voltage while engine is running ~13.8–14.5V expected.

Inspect for parasitic current draw using an ammeter.

Replace battery if it cannot hold charge.

Check and tighten all electrical connections.

Consider longer drives o r regular battery conditioning to fully recharge.
