2.  Types of Batteries

Batteries are divided in two ways, by application (what they are used for) and construction (how they are built). The major applications are automotive, marine, and deep-cycle. Deep-cycle includes solar electric (PV), backup power, traction, and RV and boat "house" batteries. The major construction types are flooded (wet), gelled, and AGM (Absorbed Glass Mat). AGM batteries are also sometimes called "starved electrolyte" or "dry", because the fiberglass mat is only 95% saturated with Sulfuric acid and there is no excess liquid.

Flooded may be standard, with removable caps, or the so-called "maintenance free" (that means they are designed to die one week after the warranty runs out). All AGM & gelled are sealed and are "valve regulated", which means that a tiny valve keeps a slight positive pressure.  Nearly all sealed batteries are "valve regulated" (commonly referred to as "VRLA" - Valve Regulated Lead-Acid). Most valve regulated are under some pressure - 1 to 4 psi at sea level.

3:What is the Service Life of my Battery Pack?

Typically 3 years of shipboard use depending upon many variables. The most important are: load and initial battery capacity (sizing), temperature, charging history, discharging history, and storage.

• Load and Battery Capacity.  If the load is high relative to the battery sizing (resulting in shorter run-times) then there is little safety margin for reduced battery capacity through aging. Therefore, battery packs will require more frequent replacement. If alternatively, the battery pack is oversized and considerable battery capacity loss (through aging) can be tolerated, then the pack will require less frequent replacement.
• Temperature affects the service life. Higher storage temperatures age the batteries more rapidly. Store the batteries in room-temperature environments. Deploy battery packs in room-temperature conditions for best performance.
• Charging History. Best battery life is obtained by storing batteries in a fully charged state. Allowing the batteries to self-discharge during storage will adversely affect their life. Allowing a battery to complete deplete itself can permanently destroy the battery.
• Discharging History. Repeated discharge to empty and re-charge cycles reduce service life.
• Storage. Batteries should be stored in a room-temperature environment in a fully charged state. If this is not possible, recharge the batteries at least every 3 months to prevent damage. Do this by powering up the UPS, starting the inverter, and letting the batteries charge for at least 24 hours.

 

4. How should a battery be stored?  

• Always store your batteries FULLY CHARGED. 
• Check all batteries once a month and recharge as needed. 
• Wet batteries can hold their charge up to 3 months. 
• Sealed batteries can hold a charge for up to 6 months. 
• When storing a chair or scooter for more than 2 weeks, charge the batteries and then disconnect them. 
• Avoid hot and cold extremes when storing.

5.How do I know if my Battery Pack is depleted?

Your pack is depleted if:

• you fail to obtain the required battery run-times,
• the Replace Battery LED is illuminated,
• it has been 3 years since the battery pack was last replaced,
• the UPS fails to Cold-Start (on battery power),
• the UPS fails to provide any battery backup when utility AC power is lost, (users often report this as " unit fails to hold load" ).
