Sealed Gell & AGM Batteries

Sealed AGM & Gel Batteries


Sealed deep cycle lead-acid batteries (gel cells and absorbed glass mat)are maintenance-free. They never need watering or an equalization charge. Sealed batteries require very accurate regulation to prevent over-charge and over-discharge. Either of these conditions will drastically shorten their lives. We recommend sealed batteries for remote, unattended power systems.

Sealed PV/solar batteries

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 and no special containers are needed. Exceptions are the three asterisked AGM models in the table, which cannot be shipped by air freight or UPS and must be shipped by truck freight on pallets. 1-year warranty.

MK sealed gel batteries

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.

MK sealed AGM batteries

These are completely sealed, absorbed glass mat, valve-regulated batteries with efficient recombination. UL Recognized components to UL MH17218. AGM batteries are recommended for battery backup standby power systems where batteries are in float service with occasional deep discharges. They can operate at temperatures from -40 to 140 F. Delivered from one of 20 MK warehouses across the US. NOTE: The 3 asterisked models in the table can NOT be shipped by air or UPS, only by truck freight.
