◎A dva ntag e of floa t an d ma intain s tage : Aft er LED t urns gre en, m ainten ance charge is provided so the battery is always in a full state. User will have access to a full battery wh enever it is disconnected from the charger.
(5)Stage 5 (analysis): The cha rger will sto p ch argi ng fo r 2 m inu tes to de term ine battery sta tus. If th e battery voltage is higher than 2.1 V per cell, the battery is d etermined as OK and will move on to stage 6. If the battery voltage is lower than 2.1V per cell, the battery fail indication will co me O N and the charger will stop charg ing. (6)Stage 6 (rec ondition boost charge): Boost voltage is provided to recondition the battery storage capacity to its original state.
