The LI72 is supplied in two variations: a two-wire version
and a three-wire version per Figure 6. The three-wire version
offers more intelligent charging features and will gradually re-
place the two-wire version.
Both of the LI72 models will charge a battery pack as fast as
its charge level will allow, and then switch over to a mainte-
nance charge to keep the charge at its maximum.
Charging Battery Packs with the LI72 Two-Wire Version
Plug the LI72 into the appropriate A.C. wall receptacle, then
insert the charge cable into the battery pack charger jack.
The charge indicator LED will indicate the status of the char-
ger as follows:
