When I bought my Quad the salesman suggested I buy a battery tender. And I think it's a very good idea, epecially if you live in winter country, and for what they want for a new battery. For winter it works well and helps keep your battery warm on cold *** nights like we have up north. Just make sure you keep the tender under cover from blowing snow or rain. It's a plus if you have power accessories like a winch for a plow. So I think it was a good $40.00 investment. It's a no brainer to install.

 

agreed

 

i have one i think it is a very good idea

 

I have the battery tender jr. didn't hook it up yet but I've heard great things about them.......

Mine are IP 65 and is build for outdoor use. Best investment ever.

 

I like these come with a cold mode for charging in cold climates used by the top car companies in the world .

In 2002, shortly after having launched their first battery chargers to the market, German manufacturer, Porsche, now showed interest for CTEK's new battery chargers. A year later, the first battery chargers were delivered. After an in-depth worldwide research of alternative suppliers, Mercedes named CTEK as their official partner of record. Since then, Maybach, Harley Davidson (Scandinavia), Aston Martin and Bentley also decided to use CTEK battery chargers under their own brand name.

Today, Ferrari also delivers a CTEK battery charger with each sold car as well aftermarket service offer chargers for those having earlier models.

Lamborghini is the latest of high performance luxury sports cars having reached an agreement with CTEK Sweden of specific battery chargers.

CTEK Sweden is proud to supply battery chargers and develop adapted solutions to some of the worlds most recognised car and motorcycle manufacturers in the world: Porsche, Mercedes, Maybach, Harley Davidson (Scandinavia), Aston Martin, Bentley, Ferrari and Lamborghini

They soung good, and good for some to know for all vehicles.
But I think I'll stick with the DelTran Tender Junior for $40.00, seems to have worked well for me. It worked and held up find outside under my tarp in -20 below nights and days. I'll use it every time I use my quad in the summer days.
Makes one less thing to worry about when I'm ready to ride or having to use my winch.

 

That`s the type I`m using. It`s common to use them in boats to here in Norway during the winter when they are not in use.
