Happy New Year to all.

Is it okay to start the car with a battery tender still connected to the battery? Or should the clips be removed before I start it?

It shouldn't matter either way, but I would unhook the tender just for safety. It doesn't produce enough amperage to help start tha car if it is a true battery tender - 1/2 - 2 Amps.

i usually disconnect my tender before i start my car although don't do it for any paritcular reason im sure it would be fine even if it was still connected... its just that once i forgot it was plugged it and it got dragged along with the car

Electrically it won't matter.

I know an idiot that did just that, fortunately i noticed before i left the driveway.

I always unplug mine before I start it, just to be on the safe side.

my tender got all busted up so back in the box it went and back to canadian tire for a exchange

I use a tender on my other car that only sees weekend duty, and I've started the car before with it hooked up - no problems...

Mine stayed in place but pulled the cord out of the wall. When i saw the cord flying, i knew i had done something stupid.

I just did this today.... unplugged the battery tender and started the car. I even remembered to take the plastic off the exhaust tips first. What I forgot to do, though, was take the moth ***** out of the engine bay. I put some moth ***** in a pair of old socks and stick these in the engine bay to kep "wire-chewers" out. Problem is, taht if you start the car and forget to take them out, your garage will stink to high heaven for a bit!

Next time don't put them on the exhaust manifold!

The tender only adds charge when needed. I have forgotten the threshold voltage. Either way, the charge it delivers is minimal (like 750 mA) for the normal car chargers.

Starting the car only puts a drain on the battery, so the worst that would happen is the battery tender switching on to recharge the battery. You would be putting an extra 750mA into the battery above what the alternator is recharging it with. No great shakes. It would take an amp of current for quite some time to boil the battery.

As an aside, you can build your own battery tender with parts from Radio Shack for WAY less than the retail ones. You gotta be handy with little electrical parts though!

Maybe true, but the $7 I paid for mine means less to me than the time to make my own. (Not that I would know how to anyway)

i paid like 50 bucks for mine!

I got three of them and they all work great.

Just FYI. They now have battery tenders that run off of a small pliable solar panel. No electricity needed. Very helpfull if you store your Vette or Boat in a barn or building without electricity. They are offered quite regularly in boating magazines & stores.

That is what I referred to above...I have 2 and they work great.
