MK sealed batteries are designed for maintenance-free operation for the life of the battery. Sealed construction eliminates periodic watering, corrosive acid fumes and spills. Tank formed plates ensure voltage matching between cells. Most models are rated non-spillable by ICAO, IATA and DOT, meaning easy transportation by air requiring no special containers. Exceptions are the three AGM models marked by asterisks in the table, which cannot be shipped by air freight or UPS and must be shipped by truck freight on pallets. MK sealed gel and AGM batteries are covered by a 1-year warranty.
The gelled electrolyte won't stratify, so no equalization charging is required. Less than 2% per month standby loss means low discharge during transport and storage. Gel batteries are best for cycling operations and where very cold temperatures are expected. They can operate at temperatures from -76 to 140 F.
