Product Details

CS FREE™ 12 V Portable Automatic Battery Charger and Maintainer by CTEK®. CS FREE gives you the freedom to charge and maintain any 12V lead acid or lithium battery wherever you are - even if you’re nowhere near a power outlet. Use it as a portable charger to top up your battery with mains power, or hook it up to a solar panel kit or 12V battery for complete charging freedom anywhere you go. CS FREE also features revolutionary Adaptive Boost technology so if your vehicle won’t start, just connect it up and CS FREE will automatically analyse the state of your battery. It’ll then work out the safest and quickest way to give it the power it needs to start your vehicle within 15 minutes. Unlike most ‘boosters’, CS FREE is sensitive and safe, so it avoids damaging your battery or your vehicle’s electronics by only giving it the charge it needs to get you going. CS FREE is also a smart maintainer and hi-tech powerbank to keep your battery and tech powered up so they’re always ready to go.

Amazing! Save My Money!
Great product. I'll buy again. Highly recommended. This has saved two AGM batteries for me so far.

Very Nice
Nice, reasonably compact for the power it generates, don't loose the manual, the little flashing light codes are not intuitive but I like it way better than others I bought.

Stay Charged
Needed something to keep my battery charged on a vehicle that is driven infrequently. I installed CTEK charger to maintain the battery and every time I go to start the vehicle the battery is fully charged.

Best Charger Ever
This is the best charger ever. I have a lead plugged into my motorcycle and 2 cars and I rotate it between the 3 of them and they start up like the battery is brand new. This will pay for itself just in not having to buy a new battery. Don't go cheap as this is the best and well worth it.
