Product Description
The blue SB350 battery connector housing is a modular polycarbonate connector component designed for 24VDC electric lift truck systems. Rated for continuous operation at 350A with 2/0 AWG cable, this blue-colored housing is keyed for a specific polarity position in your battery connection system, typically serving auxiliary load or ground return functions.
Built for durability in warehouse environments, the P844-0013 provides electrical insulation and mechanical protection for internal contacts and carriers. Proper color-keyed connectors—blue, gray, and red—must match corresponding receptacle positions to ensure correct polarity and prevent equipment damage. Replace immediately if the housing shows cracks, discoloration from heat, or loose internal contacts.

Frequently Asked Questions
Q: What is the P844-0013 connector housing and what is its function?
A: The P844-0013 is a blue polycarbonate housing for SB350 battery connectors rated at 350A, 2/0 AWG cable in 24VDC electric lift truck systems. The blue color indicates a keyed polarity position in your battery connector set. It provides electrical insulation and mechanical protection for internal contacts and carriers.
Q: What does the blue housing color indicate in an SB350 connector system?
A: The blue housing indicates a specific keyed polarity function in your 24VDC system, typically auxiliary load or ground return. Blue connectors must match the corresponding keyed receptacle in your truck battery system. Do not interchange blue, yellow, or red connectors as this causes reverse polarity faults and equipment damage.
Q: Which electric lift truck brands use the P844-0013 housing?
A: The P844-0013 fits Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT electric lift trucks with SB350 modular connector systems. Check your truck serial number and original connector specification to confirm SB350 compatibility.
Q: What is the rated amperage and cable specification for the P844-0013?
A: The P844-0013 is rated for continuous operation at 350A with 2/0 AWG cable in standard 24VDC battery systems. Do not exceed 350A or use undersized cable, as this causes overheating and contact failure. Verify your truck battery system amperage capacity matches this rating.
Q: How long does the P844-0013 housing last and when should it be replaced?
A: The P844-0013 typically lasts 3-5 years in normal warehouse duty cycles. Replace it immediately if the housing cracks, discolors from heat, shows melting near contact points, or if contacts become loose inside the housing. Frequent charge-discharge cycles and harsh environment exposure reduce lifespan to 1-2 years. A degraded housing exposes live contacts and creates electrical hazards.
Q: Can the P844-0013 blue housing be substituted with gray or other color housings?
A: No, the P844-0013 blue housing must be used in the blue keyed position of your connector system. Gray (P844-0012) and red (P844-0004) housings serve different polarity functions. Using the wrong color housing results in reverse polarity connection and equipment damage. Always match the exact housing color to the keyed receptacle position.
