2.1.1 Battery Recycling and
Disposal
Teledyne Isco offers two different batteries for use with its
equipment. Both batteries fit inside of or on top of Isco
equipment and fasten to the equipment with rubber draw
catches. Both have advantages and disadvantages. The choice is
ultimately up to you.

Nickel-Cadmium Battery, which is described in Section 2.2.
Each cell in the nickel-cadmium battery provides 1.2 VDC and
has a capacity of 4 ampere-hours (Ah). It takes ten of these cells
connected in series to make a battery of 12 volts. The cells are
packaged in an environmentally-sealed plastic housing, supplied
with a cable and two-pin M/S connector, and provide 12 volts DC.
Also available is the Isco Model 946 Lead-Acid Battery,
described in Section 2.3. This battery is a six-cell, plastic-cased,
6.5 Ah, gelled-electrolyte type, supplied with a connector. It
delivers 12 volts. A lead-acid cell provides 2.2 volts, so six are
required for 12 volts. These batteries are popularly known as
gel-cells.
Batteries of all types are a significant source of toxic and envi-
ronmentally hazardous materials, primarily heavy metals. The
disposal of lead-acid, nickel-cadmium, and alkaline batteries in
landfills every year represents a growing threat to the envi-
ronment. Legislation requiring the recycling and/or proper dis-
posal of rechargeable batteries has been passed in most states.
Because the laws vary from state to state, and in each locality, it
is your responsibility to find out how to recycle or dispose of these
products properly.
Since July 1, 1993, we have labeled all equipment containing bat-
teries with the three-arrow recycling logo and the type of battery
(Ni-Cd [nickel-cadmium] or Pb [lead-acid]).
