PS-445 is manufactured by Power-Sonic. The Power-Sonic PS-445 is a 4 Volt 4.5 Amp Hour sealed lead acid rechargeable battery.

General Specifications Dimensions: Length 1.89 inches 48 millimeters Width 2.09 inches 53 millimeters Height 3.70 inches 94 millimeters Height over Terminals 3.86 inches 98 millimeters Approximate Weight 1.43 pounds 0.65 kilograms Terminals: Quick Disconnect Tabs (0.250"x0.032") Case: ABS Plastic Electrical Specifications Nominal Voltage: 4 Volts (2 cell in series) Nominal Capacity: 20 hour rate (225mA to 3.50 volts) 4.5 AH 10 hour rate (420mA to 3.50 volts) 4.2 AH 5 hour rate (765mA to 3.20 volts) 3.825 AH 1 hour rate (2700mA to 3.00 volts) 2.7 AH Energy Density (20 hour rate) 1.23 Watt-hours/cubic inch 75.3 Watt-hours/l Specific Energy (20 hour rate) 12.6 Watt-hours/pound 37.7 Watt-hours/kg Internal Resistance (Fully Charged Battery) 15 milliohms (approx.) Charging Cycle Applications: Limit initial current to 900mA. Charge until battery voltage (under charge) reaches 4.80 to 5.00 volts at 68º F (20º C). Hold at 4.80 to 5.00 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 4.50 to 4.60 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-445 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-445 should replace the following part numbers for most applications, be sure to check dimensions, terminal size, voltage and amp hour ratings.   Brooks Equipment BAT446   Chloride 1000010118   Chloride 1000010161   Chloride ESP2   Chloride ESP2SG1A   Dual Lite 12581   Dual Lite 2B2G   Dual Lite BED   Dual Lite BEP   Dual Lite BHR   Dual Lite EDC104   Dual Lite EIC1   Dual Lite EZXRWWWEP   Dynacell WP454   Eagle Picher Batteries CF4V46   ELS EDS450   Emergi-Lite M19   Emergi-Lite M19017   Empire SLA454   GS Battery PE4V4.5 Battery Center BC445   GS Battery PE4V45   GS Battery PE4V45F2   Hi Light 3910   Interstate Batteries ASLA0826   Jasco RB445   Jasco RBX446   Jolt Batteries SA445   Kung Long WP454   Leoch DJW445   Lintronics NP424   National Battery C12D   National Battery C12DD   National Power Corp GF010R7   National Power Corp GR010R7   Newark 87F632   North Supply 782135   Ohio Medical Product 2350 ANESTHESIA   Ohmeda 2350 FINAPRES   Panasonic LCS384P   Powercell PC445       Powertron PE4V45F2   R&D 5671   Sentry Lite PM445   Siltron 1001163   Sonnenschein 1001161   Sonnenschein 4V4   Sonnenschein EP300   Sonnenschein N4812I   Sonnenschein PS445   Storage Battery Systems S445   Sure-Lites 3910   Technacell EP645   Technacell TC645   Tempest TR454   Toyo 2FM45   Trio Lighting TL930002   Werker WKA445F2   Yuasa NP424   MB5541   SLA445
