TEMCo 100 Pack Bare Copper Battery Cable Ends 2 AWG 5/16in Hole

In this review of the TEMCo 100 Pack Bare Copper Battery Cable Ends the bottom line is simple: these terminals are aimed at installers, fleet technicians, and serious DIYers who need dependable conductivity and moisture protection in bulk. The reviewer found the 99.91% pure copper construction and closed end design deliver consistent low-resistance connections and resist degradation under heat, making them a sensible choice when replacing or terminating battery cables on vehicles, marine craft, or heavy equipment.

Key Features

• Pure copper construction: Made from 99.91% pure copper for high conductivity that supports maximum current flow with minimal voltage drop.
• Heavy-duty durability: Thick, annealed copper construction resists high temperature conditions and provides mechanical strength for repeated handling and crimping.
• Closed end protection: The closed end keeps moisture and contaminants away from the cable entry, helping prevent corrosion over time.
• Precision fit: Flared openings and high-tolerance molding make wire insertion easier and yield a reliable crimp every time.
• Versatile options: Available in a wide range of wire sizes from 6 AWG to 4/0 AWG and multiple stud hole sizes to match common battery and terminal hardware.
• Crimp or solder compatible: Designed to be crimped for best results but also solderable when a permanent connection is needed.

Who It's For

The TEMCo terminal pack is best for mechanics, boat owners, fleet maintenance teams, and anyone who regularly works on batteries or power distribution and wants a bulk supply of robust, marine-grade copper ends. Buying 100 at once suits projects where multiple battery banks or wiring runs are being serviced or where spares are needed for routine maintenance.

Less ideal: a homeowner doing a one-off repair might prefer a smaller pack, and audio hobbyists should double-check fit since the recommendation is to choose a terminal one size larger for some audio wire types.

Pros & Cons

Pros

• Excellent conductivity from near-pure copper yields low-resistance connections for heavy current.
• Closed end construction and compatibility with adhesive heat shrink reduce the risk of corrosion in wet environments.
• Durable, heat-resistant build tolerates the high temperatures encountered in engine bays and marine applications.
• Precision molding and flared openings make installation faster and more reliable.

Cons

• Offered in large 100-count packs which may be more than needed for occasional users.
• Audio wire may need a larger terminal size than the wire gauge suggests, adding an extra sizing step for specialty wiring.

Frequently Asked Questions

Are these terminals suitable for marine use?
Yes; the closed end construction and annealed copper resist moisture and corrosion, and they pair well with adhesive heat shrink for added protection.

Can these be crimped or soldered?
They are designed to be crimped for the best mechanical and electrical result but can also be soldered if a permanent bond is required.

Will these fit audio wire?
They work on solid or stranded wire, but for some audio wires TEMCo recommends choosing a terminal one size larger than the wire gauge to ensure a proper fit.
