I am considering purchasing a CTEK charger and was wondering if anyone has any experience with them.

These chargers are multi mode with pulse for de-sulphation and they are low current so they are not going to evaporate all your electrolyte.. They are not for starting a car.

In Vancouver Lordco is having a sale and at 56$ for the model 3300 which is cheaper than any US price I've seen online or otherwise.
