One Word - AWESOME
- Reviewed in Canada on November 26, 2024Verified PurchaseVersatile for a wide range of battery types. Had the prior generation charger which died after about 6 years so hopefully this newer model will have better longevity.
- Reviewed in Canada on March 8, 2025Verified PurchaseIt would be nice you have better instruction.
- Reviewed in Canada on June 16, 2025Verified PurchaseExcellent for keeping off season batteries on charge (snowmobile batteries in summer and ATV batteries in winter come off my machines and stay on the charger for the off season). I have revived several batteries that appeared to be dead but came back on charge after staying on the charger for several days. Had this for a couple of years now and very happy with the purchase.

5.0 out of 5 stars Very impressed!
Verified PurchaseBought this to maintain my batteries for the boat through winter, worked perfectly! Nice compact charger, I mounted it to my garage wall above the work bench, terminal clips are moderate to heavy duty and constructed well. NOCO makes good quality products at a decent price point which is affordable.
