Best Chargers

I use several different CTEK chargers to maintain tactical systems and my home personal systems. They are simple to use and provide advanced battery care. We maintain hundreds of batteries and seen ~18 mos of additional service life by using these on a regular basis. My highest recommendation for CTEK!

This is my second CTEK charger. My original CTEK 3300 worked great for years but needed to be replaced. The MXS 5.0 has been great. Seems to get the battery to full charge a little faster than the older version, and the LED lights are helpful to let you know where it is in the cycle. These chargers are well made,easy to use,and really help batteries perform and last longer.

Small Charger packs a big punch!

I am using this charger on my 69 Camaro that is a weekend car. It has been raining the past few weekends here and this charger has kept my battery fully charge and the car starts up on the first crank. Highly recommend this charger.
