| Douglas Safeguard Flooded Flatplate Features & Benefits |
| Container and Cover |
| Cover – Flame retardant ABS to UL 94 V-0, 28% LOI,
permanently sealed to the container. Container – Transparent
Styrene Acroylonitrile (SAN), ensures optimum visibility and very high
insulating qualities which eliminates the need for separate cell
insulators. Electrolyte level and cell condition clearly seen. |
| Separators |
| High quality Porvic 2 (sintered microporous PVC) form
a diaphragm between the plates. The separators are chemically inert
with a high degree of porosity, which ensures minimum internal resistance. |
| Terminal Post |
| Heavy-duty 2- hole post with copper insert allows for
very high discharge currents. |
| Inter-cell/unit connectors |
| Heavy-duty lead-plated copper connectors minimize voltage
drop in battery circuits while delivering maximum current flow. |
| Plates Material |
| Bridge-hung Positive plates are constructed of 0.197” (5mm)
thick lead-antimony-tin selenium grids and finer oxides to bring longer
life and high capacity. The bottom-supported Negative plates provide
a perfect balance to maximize performance |
| Warranty |
| 2 years full replacement, 18 years pro-rated (20 years
total) |
| Installation |
| Lead acid batteries installed on open rail rack can be
connected with plates edge-to-edge or face-to-face. |

| Douglas Safeguard Premium Features & Benefits |
| Container and Cover |
| Made of thick wall PC/ABS with high mechanical strength
and impact resistance. Non-toxic, non-halogenated flame retardant
to UL94 VO, LOI 32%. |
| Separators |
| High quality microporous glass fibers facilitate gas
diffusion, optimize acid absorption and lower electrical resistance. Low
internal resistance, high-energy density, separator maintains compression
throughout life, giving excellent vibration resistance. |
| Terminal Post |
| Large cross section, heavy-duty post with tin plated
copper insert allows for very high discharge currents. |
| Inter-cell/unit connectors |
| Heavy-duty tin-plated copper connectors minimize voltage
drop in battery circuits. Connections do not require torque maintenance
nor grease (NO-OX). |
| Plates Material |
| Thick, pasted construction for both positive and negative
plates, with special lead/calcium/tin alloy. Resists corrosion
for up to 15 year life at 68 degrees F. |
| Warranty |
| 5 years full replacement, 15 years pro-rated (20 years
total) |
| Installation |
| Lead acid batteries housed in steel racks that can be
stack 6 or 8 modules high and meet Zone 4 seismic requirements. |
