IMPORTANT INFORMATION ABOUT BATTERIES How do you determine whether a conventionnal battery or Why should you charge your AGM battery has been charged Why do winter months seem to battery once a month? After the battery has undergone charging (as per bring more battery problemsproperly ? When not in use, a battery discharges on a daily battery manufacturer’s specifications), the following ? basis sometimes up to 0.5 to 1%. This rate of caracteristics will tell you if a conventionnal or The main reason is that the batteries have to discharge increases when the climate is warm.
