This 12 volt / 7 amp unit is suitable for vehicles and other 12 volt vehicles – boats, dune buggies, off-road vehicles, etc. The unit is easy to transport and store. The cables are well insulated and very flexible. The CTEK (56-353) is secure because it can not be activated on connection transitions.
It has 4 modes of operation for use under normal conditions, in colder climates with average temperatures of 41 degrees Fahrenheit, for reconditioning heavily discharged batteries, and for a stable 13.6 volt supply. Many drivers consider this model the best AGM battery charger due to the 8-stage charging system. However, its alligator clips are made of brittle plastic and can break easily.
- It can stay connected for several months without damaging the battery that makes the device perfect for seasonal vehicles.
- Simple plug – just supply jumpers to the charger, connect to the batteries + and – terminals and turn it on.
- Absorption phase overextends that provoke delays and make AGM battery charging too long.
- Too small positive clamps that are about one size.
