Universal Battery
Charger/Discharger
Many battery chargers
are available, but few are
universal chargers. Using
this kit, NiCd and NiMH
batteries of different
voltages can be charged
both quickly (52 minutes)
and normally (14 hours).
In order to ensure that the battery is fully discharged
prior to charging and thus has a longer life cycle, an
automatic discharger is also fitted. Specifications:
•Charge current: from 15mA~750mA (selectable) •Usable
battery voltages: 1.2V, 2.8V, 3.6V, 4.6V, 6V, 7.2V, 8.4V
and 9.6V •Automatic discharge and charge cycle
•Dimensions: 3.4" x 3.1"
