    • Great product
Using on my boat and lawnmower. Works, great! Wish I would’ve understood how easy these are to use and would’ve started using them 20 years ago! They quickly connect to any battery and plug-in to the outlet, that is all there is to it! They put out 2 A an hour. Should be solid red when connected to the battery and plugged in; flashing green when the battery is at least 80% charged And then solid green when it is 100% charged. Note: this type of charger will not charge a dead battery. ... show more

    • Works great!
I hooked this little gem up to our rarely driven CRV. The battery was D.O.A., like really dead. I had to jump the car just to get the required voltage for the Battery Tender to take over. Two days later, battery is completely charged, and now I can maintain the charge. Excellent product! Goof proof too! 🤪 ... show more

    • I love this charger!
I bought the larger full size version of this first from Costco and it never worked for what I wanted it to. It didn't charge dead batteries, and the interface made it confusing to charge different batteries. I got this one to replace it, and man, it works SO much better AND easier, even though it's smaller and called the junior. Simply plug and play, and the charger charges any battery and maintains it nicely. I have 5 vehicles so I bought two of these with a bunch of quick connect pig tails and now all my vehicles are easily maintained and charged up when needed. I accidentally left my car on ACC for like a day and a half and it was drained... plugged up the charger and two days later it was perfectly charged and good to go again. Would recommend!! ... show more

    • Having some trouble with good terminal connections
For whatever reason, this unit is finicky when connecting to the battery. I have other battery tenders from DelTran that don’t seem to have same problem. This unit won’t shift into charging modes unless the alligator clamps are very specifically oriented into the battery posts. I would have expected that any decent connection to the post or the battery terminal clamps would be adequate. But once connected, unit performs like a champ. ... show more

    • Own Three of These
I have three garage kept vehicles that are kept on these tricklers 365 days a year. I've been operating two of these for two years straight with no issues. Two of the vehicles are taken out a couple times a year for exercise and they start right up with no issues. Inexpensive, dependable, and convenient for purpose. ... show more

    • New design is really nice
I had an older model of this one, and is was still working great, never had any problems. I have it wired up to my side-by-side, and the old one always worked great with no issues, right up to the point where I drove off with it still plugged and tore it all apart. The new one has a really nice design and works just as good as the last one. Hopefully I won't drive of with this plugged in. This are great trickle chargers!! ... show more

    • What a difference
This product was so worth the price paid. I would never buy one of the cheaper versions. This is so much better and it works! The wires on the last unit that I bought were so flimsy and just broke off. I am so pleased with this product.
