The intrinsically safe battery packs require slow charging. When<br />
the packs are inserted into the charger (Figure 4-4), the yellow<br />
LED indicates that the fuse (required to maintain intrinsic<br />
safety) is good and that the circuit is powered. The green LED<br />
indicates that the undercharged battery is accepting current; the<br />
LED will go out when the battery is fully charged.<br />

It will typically take two days for the green LED to go out, and it<br />
is recommended that you continue charging for another 24 to 48<br />
hours after the green LED light goes out. The battery packs may<br />
remain in the powered charger indefinitely without damage.<br />
