The flow loggers contain internal mounting provisions for two
different types of batteries. The first type is a pair of standard
6-volt alkaline "lantern" batteries. The second is a 6.5 Ah, 12-volt
lead-acid battery, similar to the standard Isco Lead-Acid Battery,
but with a different cable and connector. You can also use the
Solar Panel Battery Charger, modified to accept a standard Isco
Lead-Acid Battery and supplied with an interconnect cable.
Electrically identical to the Model 946 Isco Lead-Acid Battery,
this battery comes with its own special cable and connector. You
must use this special arrangement with the flow loggers if you
want the battery to be self-contained, as the standard Lead-Acid
Battery will not fit inside the flow logger case. You can recharge
this battery the same as you recharge the standard Isco
Lead-Acid Battery.
Long used to power lanterns and other sporting equipment, the

rechargeable battery for the flow loggers. Because each battery
only delivers 6 volts, you must use two of them (Figure 3-2).
