Features:
17. Sealed maintenance free
18. AGM separator, cathode adsorbent technology for efficient gas recombination of up to 99% and freedom from electrolyte maintenance.
19. Equalization charges are not required and cycle or standby (or float) use.
20. Low resistance and energy output is more remarkable.
21. Fully enclosed (not liquid leakage, no acid gas spill).
22. Low self-discharge rates
23. Flame-arresting one-way pressure-relief vent for safety and long life.
24. Computer-generated grid design optimized for high power density.
25. Computer designed lead, low calcium alloy grid for minimal gassing and ease of recycling.
26. Thermally welded case-to-cover bond to eliminate leakage.
27. High discharge performance
28. High reliablitity and stable quality
29. Powerful recovery
30. Long service life
31. Wide operating temperature range
32. More deep cycle times
