    So I'm installing a permanent battery tender (this one).

    I've got it mounted in the engine bay. The instructions call for the positive O-ring/lead to connect directly to the positive terminal of the battery, and the negative to connect to a body ground point or the engine block.

    However, I can't find a suitable point anywhere within reach of the negative cable. Would it be terrible if I just connected it to the negative battery terminal bolt? It's all the same "Node" in the circuit, isn't it?

    car is a 2008 acura RL, and the tender is mounted to the right of the battery as you face the car.

    Thanks!

    Can't find a ground strap?

    I'd probably just connect it to the negative terminal honestly, lol.

    There should be a ground strap coming off the negative battery cable. just follow it it a ways...

    if you can't find it off the cable, you could find just about any bolt coming off the engine itself. most cars have multiple grounding points coming off the motor.

    but if all else fails, you will be fine grounding it to negative battery terminal

    You can either lengthen the wire so it reaches, or just go ahead and connect it right to the battery.

    there was a ground strap unfortunately getting to the nut behind it would have required taking off the bumper
