Model 3440 Appendix A–11
The gauge is equipped with a rechargeable nickel-metal hydride
(NiMH) battery pack containing five C batteries (see Figure 13).
When the NiMH batteries drop below 5.5 V, the gauge shuts off.
Troxler recommends recharging the NiMH batteries. The NiMH
batteries can be fully recharged in only three hours.
Backup gauge power can also be supplied using the AA alkaline
batteries supplied with the gauge as described.
Table 4 shows the typical operating life of a new, fully charged
NiMH battery pack and a set of new AA alkaline batteries. As
shown in the table, the typical battery operating life is impacted
by the use of the backlight and whether or not the gauge is
equipped with a GPS unit.
