Battery Pile Head
A battery pile head, commonly referred to as a battery terminal, battery post, or simply terminal, is the conductive part of a battery to which electrical connections are made. It serves as the point of contact for connecting a battery to a circuit or charger.
Material:
- Lead: Traditionally, battery terminals are made of lead or lead alloys due to lead's excellent conductivity, malleability, and resistance to corrosion. However, lead content is decreasing in newer batteries due to environmental concerns.
- Lead-Calcium Alloy: Provides improved corrosion resistance compared to pure lead.
- Tin-Lead Alloy: Used in some applications for enhanced solderability and conductivity.
- Copper: Increasingly used as a more environmentally friendly alternative, often coated with a protective layer to prevent corrosion.
Purpose:
The primary purpose of a battery pile head is to establish a reliable electrical connection between the battery's internal energy storage and an external circuit, enabling the flow of current to power devices or recharge the battery.
Function:
- Electrical Conduction: Facilitates the transfer of electrical current between the battery and the connected load or charger.
- Mechanical Connection: Provides a secure point for attaching cables, connectors, and other conductive components.
- Corrosion Resistance: Resists degradation from the electrochemical reactions that occur during battery use and charging.
Usage Scenarios:
- Automotive Batteries: Connecting the battery to the vehicle's electrical system (starter, lights, accessories).
- Backup Power Systems (UPS): Connecting batteries to provide emergency power during outages.
- Portable Electronics: Connecting batteries to power devices like flashlights, radios, and toys.
- Solar Power Systems: Connecting batteries to store energy generated by solar panels.
- Electric Vehicles (EVs) & Hybrid Electric Vehicles (HEVs): Connecting high-voltage battery packs.
Common Types:
- Post Terminals: Cylindrical posts protruding from the battery. These are the most common type, especially in automotive applications. Typically come in two sizes, SAE and DIN.
- SAE Terminals (Top Post): Common in American vehicles. Feature a threaded hole for accepting bolt-on connectors.
- DIN Terminals (European Style): Feature a smaller diameter post and often use clamp-on connectors.
- Side Terminals: Located on the side of the battery. Often found in European vehicles and some industrial applications.
- Flag Terminals: Flat, blade-like terminals, commonly used in smaller batteries for portable devices.
- Threaded Terminals: Feature a threaded stud for secure connections, often used in specialized applications.
Corrosion Prevention:
Battery terminals are susceptible to corrosion due to the acidic environment around the battery. Common preventative measures include:
- Protective Coatings: Applying grease, anti-corrosion sprays, or felt washers to the terminals.
- Terminal Cleaners: Regularly cleaning the terminals to remove corrosion buildup.
- Terminal Protectors: Using protective covers to shield the terminals from the elements.
Based on the provided information, the following HS codes may be relevant to “battery pile head”:
- 8506900000: This HS code covers Primary cells and primary batteries; parts thereof: Parts. This includes parts for primary batteries, which could encompass battery pile heads if they are considered components of primary batteries. The basic tariff is 2.7%, with an additional tariff of 25.0% (increasing to 30.0% after April 2, 2025), resulting in a total tariff of 57.7%.
- 8507904000: This HS code covers Electric storage batteries, including separators therefor, whether or not rectangular (including square); parts thereof: Parts: Of lead-acid storage batteries. If the battery pile head is a part specifically for lead-acid storage batteries, this code applies. The basic tariff is 3.5%, with an additional tariff of 25.0% (increasing to 30.0% after April 2, 2025), resulting in a total tariff of 58.5%.
- 8507908000: This HS code covers Electric storage batteries, including separators therefor, whether or not rectangular (including square); parts thereof: Parts: Other. If the battery pile head is a part for electric storage batteries but is not specifically for lead-acid batteries, this code applies. The basic tariff is 3.4%, with an additional tariff of 25.0% (increasing to 30.0% after April 2, 2025), resulting in a total tariff of 58.4%.
It is important to determine the type of battery the pile head is intended for (primary or electric storage) and, if it's an electric storage battery, whether it is a lead-acid battery to select the correct HS code.
