We use one of these for the classic mini cooper and it works great. Not sure the brand but will try to follow up with the details.

 

Will Amazon.com refuse a Battery Tender order if shipped to California?

 

I usually remove the battery from the car and put it on the tender, has been working great for last couple years and its actually meant for small
batteries like my motorcycle or jet ski haha

 

I use this one. Comes with a plug for your battery so you don't have to use the clips.

That's odd...

funny how they have this news for 2012.

Interesting.. Maybe I haven't done enough research.. It seems that the more expensive versions are legal but the $20 battery tender jr is not. Regardless, there are a few ~$20 options that people have suggested so I will pick one of those up and hopefully it does a good job. If it kills the battery then it's time for a new one anyways.

 

Don't buy a crappy battery tender/charger. As someone from a place where you can only drive a nice car about 4 months of the year due to snow/ice/rain etc... many nice cars (new and classic) + boats have been lost due to the battery being overcharged and catching on fire because the $15 or $20 battery charger failed.

I used to only charge my battery once a month for a couple of hours with a $10 dollar harbor fright equivalent quality charger for fear of this.

I have since bought this one:

I paid if I remember $75 CAD for it, I waited for a 40% off sale at Canadian Tire (kinda like a mix of Home Depot + Orchid Supply Hardware).

I also used the NOCO G7200 to recover the dead OEM battery because I let it go flat too many times over the years of never driving my s2000. I took the battery out and set it recover (desulfate mode) for a day.

 

I didn't know they were illegal? I have the Jr one for Irene...

 

just a heads up: Costco has this battery tender for $39.99 now. Saw it at the San Bruno one on El Camino. Seems like it had good reviews on Amazon. i might pick up one, but i kinda want my battery to die, so i can get the lightweight Shorai package from KC Machine. lol

Can you use any tender for any battery? What would or wouldn't work for the KCMachine shorai, for example?
