kasi pinacharge ko lang battery ko for 2hrs. Kung yung readings ng volt meter is nasa around 13.5 to 14, ok paba battery ko? hindi ko pa kailangan palitan??
If youre referring to the alternator, 13.5V to 14V is a good indicator. If youre referring to the battery, voltage is not the accurate indicator, its the current output. You can DIY checking using several 100Watt bulb and timing the discharge rate and monitoring with Voltmeter. Check if there are visible bubbles inside the cells,excessive bubbles means worn plates.. Best if you can bring it to battery shop, they have the appropriate equipment to check if battery is still producing the right ampereage.
