For use in floor-cleaning machines, lift trucks, personnel carriers, and other vehicles that require power over an extended time, these deep-cycle batteries can handle many charge/deep-discharge cycles. They are wet cell, so they contain electrolyte in an unsealed container and must be mounted upright. They may occasionally need to be filled with distilled water.

Reserve capacity is the number of minutes that a new, fully charged battery can continuously discharge at 25 amps at 80° F. Marine cranking amps is the maximum amps that a new, fully charged battery can continuously deliver for 30 seconds at 32° F.

Warning: Batteries should always be charged and discharged in a ventilated area.

Power portable lighting such as lanterns, flashlights, and barricade lights. When choosing a battery, use the capacity, measured in milliampere-hours, to compare among similar sizes. The higher the mA-hr. rating, the longer the battery should last.

Replace batteries less often—these batteries last at least twice as long as standard sealed large-cell batteries. Use them to provide backup power for emergency lights, alarm systems, uninterruptible power supplies (UPS) for computers, and other systems that require power over a long period of time. All are dry cell, so they have an absorbed glass mat (AGM) that soaks up the electrolyte and can be used in any position except upside down. They can be recharged hundreds of times.

Change batteries less often—these last at least twice as long as standard lantern batteries. Use them to power lanterns, barricade lights, and telecommunications devices. Because they are zinc air batteries, they require oxygen to create power. Activate by removing the tape from the holes in the battery case, allowing oxygen to flow inside. They maintain voltage at a constant level, even during power peaks and pulses that can temporarily drain oxygen. Mount in any position with access to air.

Deliver a surge of power to start automobiles and other vehicles, and provide power over a long time. These batteries are deep cycle, so they can handle many charge/deep discharge cycles.
