They work for what they’re needed for. However the plastic cover for the screw terminals is very difficult to use. It needs to be slightly bigger to realm fit the terminal correctly. There’s no way you’ll get this apart it needed without breaking it. Be sure you’re done when you put it on

Instantly longer. Just add a little quality electric tape over the joints..

Like everything no dislike. Use it to charge 3 batteries on my boat. Works great
David K Stewart –
Used this with the onboard charger to reach the battery located at the back of the boat. Great quality!
Wells Turnage –
Tinned wires, fully assembled quality unit. One star off for being overpriced.

Just the right length and easy to install.
Mark Sierakowski –
Solid, quality materisls, excellent design. If you needctobrunva battery extension cable, this is it!

Good quality product. Reason for low rating on installation was because the ends had to be removed in order to snake it through the hull. Opening in the center console was to tight to pull through. Since the original cable that is permanently attached to the charger has fuse holders already installed. Cut the extension just behind the ones there. After running the cable installed terminal ends using water proof splice. Works as advertised.
