General Electrical RequirementsBatteriesTS 1.1.14Low-Voltage Batteries (24V)Default Four Group 31 Maintenance-Free Batteries Four Group 31 Series deep cycling maintenance-free battery units shall be provided. Each battery shall have a minimum of 700 cold cranking amps. Each battery shall have a purchase date no more than one year from the date of release for shipment to the Agency.
Two 8D Battery Units Two 8D battery units conforming to SAE Standard J537 shall be provided. Each battery shall have a minimum of 1150 cold cranking amps. Each battery shall have a purchase date no more than 120 days from the date of release, and shall be fully maintained prior to shipment to the Agency. The battery compartment must be well-ventilated to prevent hydrogen buildup while protecting the compartment from road spray, water intrusion and de-icing chemicals.

Battery compartment must be well ventilated to prevent hydrogen buildup while protecting the compartment from road spray, water intrusion and de-icing chemicals.
Same Size Terminal Ends Positive and negative terminal ends shall be the same size.
Different Size Terminal Ends Positive and negative terminal ends shall be different sizes.
Capacitor Start System A capacitor start system will be provided to assist with starting the bus. This system will be isolated from the regular starting system to prevent the capacitors from draining during regular operation or long periods of down time.
2100 strand 4/0 cable or greater recommended. Alternative Color code each voltage. TS 1.1.16Jump StartDefault No requirements for jump-start connector. Alternative Jump-Start Connector A jump-start connector, red for 24V and blue for 12V, shall be provided in the engine compartment, equipped with dust cap and adequately protected from moisture, dirt and debris.
Jump-Start Connector A jump-start connector is located next to the battery disconnect switch.
The vehicle shall be equipped with a 12VDC and 24VDC quick disconnect switch(es). The battery compartment door shall conveniently accommodate operation of the 12VDC and 24VDC quick disconnect switch(es). The battery quick disconnect access door shall be identified with a decal. The decal size shall not be less than 3.5 × 5 in. (8.89 × 12.7 cm). The battery hold-down bracket shall be constructed of a non-metallic material (plastic or fiberglass). This access door shall not require any special locking devices to gain access to the switch, and it shall be accessible without removing or lifting the panel. The door shall be flush-fitting and incorporate a spring tensioner or equal to retain the door in a closed position when not in use. The batteries shall be securely mounted on a stainless steel or equivalent tray that can accommodate the size and weight of the batteries. The battery tray shall pull out easily and properly support the batteries while they are being serviced. The tray shall allow each battery cell to be easily serviced and filled. A locking device shall retain the battery tray to the stowed position. If not located in the engine compartment, the same fire-resistant properties must apply to the battery compartment. No sparking devices should be located within the battery box.
Turning the master switch off with the powerplant operating shall shut off the engine and shall not damage any component of the electrical system. The master switch shall be capable of carrying and interrupting the total circuit load. Default Single Switch The batteries shall be equipped with a single switch for disconnecting both 12V and 24V power. Alternative Separate Switches The batteries shall be equipped with separate switches for disconnecting 12V and 24V power.
Solenoid Battery Cutoff A multiplex system activated battery cutoff solenoid to disconnect battery except critical items.
Master Battery Switch Access Panel Door Lock Lock should be accessed with a standard square key.
Voltage monitoring and over-voltage output protection (recommended at 32V) shall be provided. Dedicated power and ground shall be provided as specified by the component or system manufacturer. Cabling to the equipment must be sized to supply the current requirements with no greater than a 5 percent volt drop across the length of the cable.
Circuit breakers or fuses shall be sized to a minimum of 15 percent larger than the total circuit load. The current rating for the wire used for each circuit must exceed the size of the circuit protection being used.
