How Do I Know If My Agm Battery Is Healthy. If the battery is a new or neatly used one figuring out where the label is on it would not be a hard thing to do. If it has disconnect the charger from the wall outlet and remove the good battery from the charger.

In such cases you will have to either call for professional help or get a replacement battery as soon as possible. Allow it to charge at a low rate2 amps or less for a few hoursThe charger reads the first battery as goodand will allow itself to charge it along with the dead AGM battery. When compared to flooded batteries of a similar capacity the charging rate can reach five times faster with the same power source.

The state-of-charge voltage varies slightly depending on the type of deep cycle battery being used. It can be avoided if you plan ahead of time and monitor the health of your battery at all times. However if the reading is below 10. For example if your AGM deep cycle battery rates at 1230V its at a 70 state of charge as shown on our State of Charge graphic.
