United Bravo Not Starting After a Few Days of Inactivity – Battery Keeps Going Dead

My Bravo stays parked for 3–4 days without use, and every time I try to start it afterward, the battery is completely dead. I have to jump-start it each time. Is this a common problem with United Bravo cars? Could the stock battery be too weak, o r is the alternator not charging properly? What’s the best long-term solution—should I upgrade the battery o r install a cutoff switch?

When the Bravo sits unused, the small battery often loses charge quickly due to ECU memory and security system draw. Many owners face this after 2–3 idle days.

Possible Reasons:

The stock battery capacity 35Ah is too low for the car’s electrical setup.

Alternator charging is weak — it charges while driving, but not enough if you only take short trips.

Poor grounding under the battery tray can reduce charging efficiency.

Fix / Recommendation:

Upgrade battery to a 45–50Ah model AGS GL-50, Volta CR-50, etc..

If the car remains unused often, install a battery cutoff switch o r use a trickle charger.

Ensure alternator output and ground connections are solid.

Avoid frequent short trips less than 5–10 km that don’t recharge the battery fully.
