Front terminal batteries
Front terminal batteries are absorbent glass mat batteries and valve regulated batteries.
Advantages of Front Terminal Batteries
- Spill-proof through acid encapsulation in matting technology.
- High specific power, low internal resistance, responsive to load.
- Up to 5 times faster charge than with flooded technology.
- Better cycle life than with flooded systems.
- Water retention (oxygen and hydrogen combine to produce water).
- Vibration resistance due to sandwich construction.
- Stands up well to cold temperature.
- Less prone to sulfation if not regularly topping charged.
- Has less electrolyte and lead than the flooded version.
Limitations
- Higher manufacturing cost than flooded.
- Sensitive to overcharging (AGM has tighter tolerances than gel)
- Capacity has gradual decline (gel has a performance dome)
- Low specific energy.
- Must be stored in charged condition (less critical than flooded)
Main Applications
- Telecommunications
- Emergency power
- UPS
- Electrical Power plants and substation
- Transportation
