    will it jump start lead acid batteries

    Answer This Question

    The user guide says the GBX55 powers 12 v lead acid batteries "only". This sounds like it can not start a vehicle with an AGM battery.

          1 Answer | 
          Answer This Question

          The GBX75 can detect the battery's voltage level, but it does not feature a voltmeter display. It cannot read the CCA rating of a battery.

                      The NOCO GBX155 Jump Starter is the best we have ever owned. It has enough power to jump start a V8 several times before needing a recharge. The included pouch makes it convenient for storage.

                      Worked for 10 months
                      I bought this in January and it worked great- it easily jumped off my 2500HD. However, it is now November and it no longer holds a charge and is rendered useless. Of course, it’s past the return period as well. This costs too much to only be operational for 10 months.

                        Very happy to have this dependable unit
                        Great product works on our ford 350 diesel 7.3 L truck, Ford Ranger 4.0L and multiple other trucks and cars for our family. Came in great looking packaging with 12 volt car charger and USB charging cable. Unit has ports to plug in your phones, iPad and other devices. Light on unit is great idea for night time connections and repairs. Unit charges much faster than older models. Note must have car/truck running to properly fully charge unit. I was disappointed that unit didn't come with a house AC charging system, NOCO website has the house charger U65, 65W USB-C Charger with carrying case. Charges up to five times faster than traditional USB wall or car chargers. Cost about $ 70.00 plus shipping. That is why it didn't give it 5 stars. Very happy to have this dependable unit with me when traveling or on that very cold morning the car or truck will not start.

                        Don't Call A Tow Truck For A Jump Start
                        This is a very nice piece of equipment to have. I have used it at least a half dozen times and it performed perfectly. It's small, powerful and easy to use. It's been used on both a cars and SUVs. No more cumbersome bulky jumper cables. Had to call a tow truck once, they carried the same brand (different model) on the truck, so I bought this one.

                        Works very well. It started my v6 truck easily. It charges with any standard laptop C-Port charger making getting replacement chargers very easy. I work in IT so laptop chargers are a dime a dozen since we keep the chargers when computers are upgraded or salvaged.
