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.

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

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. 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.

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.

Start automobiles and other vehicles with a surge of power. These dry-cell batteries have an absorbed glass mat (AGM) that soaks up the electrolyte, so they’re usable in any position except upside down. They can be recharged hundreds of times.

Cold cranking amps is the maximum amps that a new, fully charged battery can continuously deliver for 30 seconds at 0° F.

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

Deliver a surge of power to start automobiles and other vehicles. These wet-cell batteries contain electrolyte in an unsealed container, so they must be mounted upright. They may occasionally need to be filled with distilled water.

Cold cranking amps is the maximum amps that a new, fully charged battery can continuously deliver for 30 seconds at 0° F.

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.

An alternative to wet- and dry-cell large-cell batteries, these lithium iron phosphate (LiFePO4) batteries charge more quickly and can be recharged thousands of times. With excellent chemical stability, they reduce the risk of thermal runaway if exposed to overheating or short circuiting. Use them for uninterruptible power supplies (UPS) and emergency lights.

Note: These batteries must be used with LiFePO4-compatible chargers.

Chargers (sold separately) automatically switch from fast charging to maintaining the charge level, so they won’t overcharge and damage the battery.

Check battery status from your phone. These batteries connect to a mobile app via Bluetooth, notifying you when charging is needed or finished to minimize downtime in your operation. The app also shows the status of current, capacity, and voltage. Compared to wet- and dry-cell large-cell batteries, these lithium iron phosphate (LiFePO4) batteries charge more quickly, are half the weight, and have a longer life—they can be recharged thousands of times. For constant, reliable power, they protect from overcurrent, overvoltage, overheating, and short circuits. Batteries must be used with LiFePO4-compatible chargers.
