HULKMAN Sigma 5 Amp Automatic Car Battery Charger and Maintainer

A lot of Cadillac 2000 Escalade having problems with it now for 2 years trying to get the battery to hold a charge gone through several batteries several chargers what was the best was the amazement I have in your products both the charger maintainer and the jump starter since I've had these I've had limit on problems your brand has definitely got my attention everything about it I'm 63 years old and the only thing that confused me is how you could put so much power in a small parcel but definitely a positive for the jumper and the charger one thing just to add I appreciate the opportunity to purchase from your site I don't like buying through the middleman can't wait to see what other products you come up with and what's available I am completely impressed I don't have the words to say how impressed I am with hulk man keep it up and thank you so much

I didn’t know that I was going to be charged a foreign transaction fee?

The is a premium tool that does what it advertises!!! Also bought the battery booster! Good stuff!!!

I am a Ford Master technician. I Purchased the HULKMAN Sigma 5 to mainly maintain the batteries while programming or updating the customer vehicles modules. A few days ago, the AGM battery on one of my personal vehicles died & did not start with a jumpstarter. I used the Sigma 5 to repair the battery, and it worked like a charm. Very handy, Reliable, and well worth the money.

Fits in my tool box nicely

Well it's easy to set up everything is plug a play my only question is did my battery fully change the the last bar was still flashing after after 2 days of changing so I never got a full change imo.the prive is great for the quality so im happy the only thing I would suggest is some kind of storage for it a bag or something

It kept my battery charged while I was on vacation for a week.
