Discontinued - NO Direct Replacement, Recommend PSC-121000A-C Powersonic PSC-12800A-C Sealed Lead Acid Battery Charger - Automatic Switchover 12 Volt/0.8 Amp Nominal

A-C series chargers are new switching type devices which operate without the use of transformers. I.C.‚¬TMs control and regulate current and voltage and automatically switch from the higher fast charge voltage to the lower float voltage when batteries are very close to being fully charged. At the float voltage it is safe to leave the battery connected to the charger indefinitely, making charging pretty much fool-proof.
