Can I ask how long should I use the car to fully charge its battery? My battery drained dahil ilang weeks na hindi nagamit. We seriesed it then drove for 3 hours. Then shut down the engine. Pag bukas ulit ng makina it's having a hard time starting up. We tried to engage the ignition for like 20 seconds saka sya nag start.
Ano kaya problema? Kulang lang ako sa recharge? Something wrong with the battery? Or is it with ignition?

If the battery is old, it gets sulfated very easily. It will not hold the charge like a new battery would. Try using a battery reconditioner with desulfation function and retest.

April 8th, 2018 08:15 AM #4If you have a multimeter, the voltage of the battery should be around 12.6 volts when the car is off. When the car is on with a/c, headlights, stereo, etc. on, it should read about 13.5-14.5 volts. If your reading is below that, then, there is something wrong with your alternator and it is going to kaput!
If, however, your alternator is ok and if the battery is the maintenance free type and is nearing the 2 year mark and it won't charge no matter what, then, it's time to buy a new one. Just call Motolite and they'll install and delivery it for you at your doorstep. They will also check your alternator to see it's ok.
Don't trouble yourself charging it relentlessly, hoping it might spring to life. You'll have more headaches with a discharged battery. Your car won't start in the middle of the road and you to have to push it.

Bring it to a Motolite shop (or any reputable car battery store you want). They have the necessary instruments that can check both the battery’s health and the vehicle’s charging system. The service is free and you can always go to a different shop to get a second opinion.
In my personal experience, in most cases, I was able to bring the battery back to health by charging it with a proper battery charger for several hours. Your mleage will vary depending on the battery’s age and how well it was maintained. I’d do this first before considering replacing it.
Unless absolutely necessary, don’t use the vehicle charging system to charge a depleted battery. This puts a lot of stress on the circuit and can accelerte wear on the alternator brushes, among others. If it can be helped, always charge a depleted battery using an external battery charger.

April 8th, 2018 11:10 AM #8I use in-car voltmeter for monitoring voltages and have an automatic car battery charger desulfator for maintaining battery health at home.
