I bought a CTek Multi US 3300 charger to use with 3 of my cars and my lawnmower. I have a Ctek 56-261 Comfort Connect 3/8" eyelet cable on my RV and mower batteries. It's good to know that I can leave the mower charged all night or longer without removing the battery from the mower, and it is totally safe.two more cables for wife's SUV and daughter's pickup truck.If they need to charge the battery while I'm away, they just need to plug into the charging cable, plug in the charger, and set the mode on the car charger .Don't worry about reverse polarity, terminal sparks, improper grounding, or loose terminals. 3/8" connectors fit the battery terminals on all my vehicles. There is no need to drill a hole to install the screw on the clamps. If you're away from home and need a transition, the connectors can be left in place and standard patch cords used. Another plus, especially for the charger, is that it's small enough to take with you on trips where a standard charger takes up too much space. It's a great system and the support is top notch. The only downside is that the cable is a little short, but I'm pretty sure this is to keep it from touching the moving parts of the engine while the car is in motion.
