Sealed Lead Acid (SLA)
Sealed lead acid batteries are sometimes referred to as VRLA (valve regulated lead acid) and there are two primary types AGM and Gel. We offer both AGM and Gel batteries, each has its advantages over the other depending on the specific application. SLA batteries usually last between 3 to 5 years with typical usage. The optimum operating temperature for the lead-acid battery is 25°C (77°F). Elevated temperature reduces longevity. As a guideline, every 8°C (15°F) rise in temperature cuts the battery life in half.
The nickel–cadmium battery is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation NiCd is derived from the chemical symbols of nickel and cadmium. NiCd batteries have a longer shelf life of around 10 years. The NiCd batteries sold on this site are High Temperature NiCds batteries with outstanding charge/discharge characteristics at both room temperature and high temperature up to 70°C (158°F).
Warning: Batteries, battery terminals, and related accessories can expose you to chemicals including Cadmium and Cadmium compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to https://www.p65warnings.ca.gov
Emergency Lighting has access to many internal circuit boards for emergency lights and exit signs. If you can't find it on the site send us an email with a picture of your circuit board and the product SKU it goes into and we will see if we can get it for you.
Nickel Metal Hydride (NiMH)
A nickel metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery. A NiMH battery can have two to three times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery.
Lithium batteries are primary batteries that have metallic lithium as an anode. These types of batteries are also referred to as lithium-metal batteries. They stand apart from other batteries in their high charge density and high cost per unit. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V to about 3.7 V.
Lithium Iron Phosphate (LFP)
The lithium iron phosphate battery or LFP battery, is a type of lithium-ion battery using lithium iron phosphate as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. The energy density of LiFePO? is lower than that of lithium cobalt oxide, and also has a lower operating voltage. The charge-discharge profiles of LFP cells are typically very flat. The main drawback of LiFePO? is its low electrical conductivity. Therefore, all the LiFePO? cathodes under consideration are actually LiFePO?/C. Because of low cost, low toxicity, well-defined performance, long-term stability, etc. LiFePO? is finding a number of roles in vehicle use, utility scale stationary applications, and backup power. LFP batteries are cobalt-free.
