Constant-voltage charger for Globe-Union 12-V gelled-electrolyte storage batteries can provide either fast or float charging. Constant voltage is maintained by series power transistor and series-connected zeners. Output voltage is 13.8 V for float charging and 14.4 V for fast charging.-E. Noll, Storage-Battery QRP Power, Ham Radio, Oct. 1974, p 56-61.
