My Century Marathon lasted 28 months that came with 18 months warranty. The battery died while stucked in traffic jam. The towing truck guy jump started the battery and next day the car could be started easily. So I went to the shop and checked the charge and the reading was still ok, puzzling with the reading, the shop worker asked his boss to check further. The boss way of checking was to hold on the check button for 5-10 seconds before releasing it. And the reading did slowly decreased showing the condition of the battery was deteriorating and immediately i changed a new one.
If car is running, and alternator is working, even if take out battery, the engine probably won't die ?
On another note, last Fri the crank took 1 second longer and immediate I feel the car battery going to die.
Weekend car cannot start. Checked and replaced.
Old battery taken out = 11.8V can't crank anymore.
New battery with engine running = 14.2V (60Ah, 680A cold cranking amps)
