PS-640 is manufactured by Power-Sonic. The Power-Sonic PS-640 is a 6 Volt 4.5 Amp Hour sealed lead acid rechargeable battery.

Charging

Cycle Applications: Limit initial current to 900mA. Charge until battery voltage (under charge) reaches 7.20 to 7.35 volts at 68º F (20º C). Hold at 7.20 to 7.35 volts until current drops to approximately 45mA. Battery is fully charged under these conditions, and charger should either be disconnected or switched to "float" voltage.

"Float" or "Stand-by Service": Hold battery across constant voltage source of 6.75 to 6.90 volts continuously. When held at this voltage, the battery will seek its own current level and maintain itself in a fully charged condition.

The PS-640 is a Sealed Lead Acid (SLA) battery fixes the acid electrolyte in an absorptive fiberglass mat. The advantage of this design is that the battery needs no water additions, can be operated in any position, and can be used in close proximity to people and sensitive equipment. Additional benefits: maintenance-free, sealed no-leak design, higher cranking amps, lower self-discharge, greater vibration resistance, heavy duty, no-corrosion terminals.

The PS-640 should replace the following part numbers for most applications, be sure to check dimensions, terminal size, voltage and amp hour ratings.
