Low Maintenance batteries are permanently sealed at the time of manufactureThe use of lead-calcium and AGM technology instead of lead-antimony allows the battery acid to be fully absorbedFor this reason, Low Maintenance battery case is dark and the cell caps are not removable, since there is no need to check electrolyte levelNEVER attempt to add electrolyte or water to Low Maintenance batteryDoing so will damage the case and shorten the life of the batteryNOTE: New Batteries: Batteries must be fully charged before use or battery life will be reduced by 10-30 of full potentialCharge battery for 3-5 hours at current equivalent of 110 of the battery's rated amphour capacityDo not use the alternator to charge new batteryNEVER attempt to add electrolyte or water to Low Maintenance batteryDoing so will damage the case and shorten the life of the batteryTO SERVICE LOW MAINTENANCE BATTERY:
