![]() On sealed-top batteries that do not have a built-in charge indicator, the state of charge can be determined by checking the battery's base or open circuit voltage with a digital voltmeter or multi meter. The indicators fairly give us an idea what to with the battery.įOR A CAR BATTERY THAT DOES NOT HAVE A BUILT-IN HYDROMETER If a light yellow color is visible, it indicates the electrolyte level is too low. When the ball sinks, the unit shows up dark, indicating the battery is discharged. When the ball is floating, it shows as a bright green dot indicating the battery is 80 percent charged. It contains a small green or other color ball that floats when the electrolyte specific gravity is within a certain range. A clear or yellow indicator means the level of electrolyte inside has dropped too low, and the battery should be replaced.Īctually, Battery state of charge is often indicated by a float device built into the battery. No dot (a dark indicator) means the battery is low and should be recharged before it is returned to service or tested further. A green dot means the battery is 75% or more charged and is okay for use or further testing. The charge indicator only reads one cell, but usually shows the average charge for all battery cells. These sealed-top batteries have a built-in hydrometer to indicate charge. Some car battery also has a color indicator which displays battery status & it still requires distilled water to be added as the battery is not fully of zero maintenance. #Car battery indicator no color how toRe: Guide: How To Make Your Car Battery Go On & On!ĪBOUT CAR BATTERIES HAVING A BUILT-IN HYDROMETER - COLOR INDICATOR See the photos below which would give the correct picture. The stock battery capacity fitted in Honda city is rated at 27AH (5 Hrs) / 30 AH (20 Hrs) /12V.Įven among Honda city cars, there are variation in the battery which comes with the car. God only knows what would be the choice of today’s car manufactures! Reputed battery brands of today have from cheap to expensive varieties. But we had no different versions like what we have today. In the past, all those OE battery which came with the car used to last minimum 3 to 4 years and for Diesel cars it might be one year less. He agreed and requested me to suggest a good battery I told him to go for a better battery and advised him a short run periodically to maintain it. The battery is already very week and the OE warranty of one year was over and it is almost 22 months by now. I understood that whatever effort is taken, it is not going to serve him as he would again start and use the car only after 10 days or later. We were discussing whether to jump start the car or removing the battery to send for external re- charging. I put the battery monitor into the 12V socket (cigar light) and switch on the ignition, it was showing 5 volt. I have a handy tool- the Electronic Battery Volt Monitor which I purchased online and I could spare sometime in the evening to help him. He called me and said, “Doctor what’s the problem with my car, please help me” One word about that car, it is deprived of owner’s attention, runs hardly 15 to 25 kms per month and most of the days not even cranked. On that day, my colleague’s ANHC 2011 model parked always next to my ALBUS, refused to start. ![]()
