LI72 2-Wire Charger

LI72 3-Wire Charger

The LI 72 is supplied in two variations: a two wire version and a three-wire versionper Figure 6. The three-wire version offers more intelligent charging features and will gradually replace the two-wire version as production is ramped-up.

Both of the LI72 models will charge a battery pack as fast as its charge level will allow, and then switch over to a maintenance charge to keep the charge at its maximum.

Charging Battery Packs with the 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 charger as follows:
