Although a wet/acid design is initially less expensive and can provided about 10% more running time per charge than a gel/sealed battery of equal size, a wet lead/acid battery has a much shorter service life, requires regular maintenance and poses a much higher safety risk because of potential battery acid contact and/or explosion.
An MK gel/sealed battery, instead provides an inherently safer, truly maintenance-free design. MK batteries provide a significantly longer life-averaging 1 to 2 years or longer when properly maintained - and are available in models approved by major airlines and other public transportation providers.
