Leoch AGM Batteries are valve regulated lead acid (VRLA) batteries with absorbed glass mat (AGM) separators. They are therefore classified as non-spillable and maintenance free. Additional battery trays are not required for AGM batteries.
The deep cycle battery is part of Leoch’s “Scrubber Sweeper” line and comes as a 6 Volt battery in the well known L-16 shape. The L-16 shape features a low ‘footprint’ suitable for smaller enclosures. Dimensions are (in mm) 295(L) x 180(W) x 428(H).
The capacity at the 20 hour rate (C20) is 390 Amp-hours, and the life expectancy at 20% depth of discharge (meaning your battery remains 80% full) is in excess of 3000 cycles.

General Features

  1. High capacity design, higher energy density.
  2. Excellent deep cycle property, Longer service life .
  3. Private grid construction design and paste recipe,high charging acceptance ability.
  4. Private valve regulated seal construction, safe and reliable.
  5. Outstanding vibration-resistant, wide operation temperature.
  6. AGM separator, no fluid electrolyte, guarantees oxygen recombination inside the battery.
  7. High purity lead calcium alloy, maintenance free and lesswater losing.
  8. Lower self-discharge, better storage capability.
  9. Advanced inter partition (TTP) welding technology obtains shorter current transfer path so as to get lower electrical resistance.
  10. Strength-enhanced containers and lids are made of polypropylene (PP) to keep tight assembly of batteries.
  11. Adopt heat sealing technology to seal container and lid, absolutely no leakage.
  12. High strength terminals with high conductivity are very good at high current discharging.
  13. Strength-enhanced containers and lids are impact resistant and made of polypropylene (PP).
  14. Attached protective covers for terminals and removable carry handles are convenient for operation.
