12VDC 500MA 2.5MM X 5.5MM PLUG POWER SUPPLY FC1250B FLOATING CHARGER FOR SEALED LEAD ACID BATTERIES

12VDC 500MA 2.5MM PLUG FLOATING CHARGER FOR SEALED LEAD ACID BATTERIES Use on Lead-Acid (10-15% C=Capacity) Ni-Cad (10-20% C), Ni-Mh (20-50% C) at fast charge Trickle Charge rate is about 8-12% of max. charging rate under "Max. MA" column for example: To charge LA1278 cell (12V 7.8A): prefer charging rate: 10-15%C x 7.8A=0.78A~1.17Amp FC-1250B: max charger rate 500mA/7800mA=6.4% - it's slower but easy on the cells for the long run (i.e., alarm backup) FC-1212B: max charger rate 1.2Amp/7.8Amp=15.4% - faster initially until trickle rate kicks in FC-612C: select 12V DC & 600mA - charge rate 600mA/7800mA=7.7%
