FAQs about the 500 Amp Battery Clamp Red 123-CL11
- What’s the difference between the red and black version?
Functionally, they’re identical. The red clamp is used to identify the positive terminal, while the black is used for negative or ground—helping avoid connection errors. - Can this be used with lithium batteries?
Yes, it’s suitable for all battery chemistries including lithium, AGM, GEL, and lead-acid, as long as the current does not exceed 500A. - What cable gauge should I use?
For optimal performance, pair with a thick cable such as 10mm² or larger to support high current flow. - Is this clamp reusable?
Yes. It’s built for repeated use in professional environments. If properly installed, it offers long service life. - Do I need a matching black clamp?
Yes, for full circuit applications (positive and negative), pair this with the 123-CL10 500A Battery Clamp Black, available separately.
