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. 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.

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

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.

Fast-Charging Large-Cell Batteries

K

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

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.
