[This review was collected as part of a promotion.] We have a new driver in the house which means mom and dad worry. DeWalt battery charger to the rescue. 🛟 We were able to determine that our son’s used vehicle needed a new battery after testing with the DXAEC100. I loved that we could even check is alternative. This product allowed us to do some preventative maintenance so he was not left stranded on the road.

[This review was collected as part of a promotion.] I recently tried the DeWalt DXAEC100 Professional 30 Amp Battery Charger and Battery Maintainer, and I must say, I am thoroughly impressed. This multi-tasking device offers a comprehensive solution for maintaining 12-volt WET, GEL, and AGM batteries with efficiency and ease. One of the standout features of this product is its powerful 100-amp engine start capability, which has proven to be incredibly useful in jump-starting vehicles when needed. The 30-amp charging capacity ensures a reliable and fast charging process, while the 3-amp maintainer function helps keep batteries in optimal condition over extended periods. I particularly appreciate the alternator check feature, which allows me to quickly test my vehicle's alternator for proper operation, providing valuable insights for maintenance and troubleshooting. The innovative electric pulse technology is a great addition, effectively targeting sulfate build-up on battery plates to enhance charge capacity and prolong battery lifespan.
