Great way to make sure your bike starts

Robert April 16, 2026

I use it on my Suzuki motorcycle. I have the wire attachment hooked to the battery at all times so I can plug it in when I'm not writing it to keep the battery fully charged and it works wonderfully well worth the money.

Simple to use battery maintainer

Reviewizard December 3, 2019

I tested the Stanley battery maintainer as a Spark Reviewer. The charger is simple to use and very compact. Just hook it up and it figures out what type of battery it is and what it needs to do. The cords coming out and going in to the unit have plenty of length to reach the battery and an outlet. Anyone buying this should be aware that it is not designed to jump start a vehicle. It slow charges and maintains a battery at the correct charge level without the risk of overcharging it. Perfect for winter storage of your special vehicle, motorcycle, or riding lawn mower. I would recommend this trickle charger.

Easy to Use!

AC December 10, 2019

This Stanley battery charger/maintainer is a great item to have. It is an easy to use charger that is great if you have any cars/ lawn mowers/ATV's, etc. that are not used all the time to keep the battery charged or a quick and easy way to charge it back up. The charger comes with clamps and battery rings so you can charge it either way. The charger has light indicators on it to let you know when it is in the charging process and when it is fully charged. The directions are very clear and descriptive and make it very easy to understand. The cords on it are pretty long which makes it easier to charge something if you charge it while leaving the battery in the vehicle instead of taking it out. This battery charger works well and is easy to use.

Good Little Charger

gussie1514y May 6, 2022

This is a good charger to help keep vehicle batteries maintained. It's going to be very helpful to keep the battery charged on my lawn mower over the cold winter times. There are two kinds of connectors included, clamps and O rings, which are very helpful for different types of batteries. It has a very long cord (12ft). Which is great. No need to make sure the batteries are placed real close to the charger. It's small compact size makes it very easy to store in the cabinets in the garage. It has lights to let you know it's working. The green light lets you know the battery is fully charged. Very easy to use. A good charger to have on hand.

High Hopes

wallyworldshopper January 20, 2021

I have not used this Stanley Battery Charger yet, but it is a LOT SMALLER than the advertised size. I don't really mind the smaller size but someone could look at the products that are described and make an assessment of the product. As long as it does the job being smaller and may have some advantages.

Fits all batteries

Julzann December 6, 2019

This comes with both battery clamps and battery ring terminals so it can fit all batteries. Very clear status indicators so you know when your battery is fully charged. This really isn't made to charge a completely dead battery but to help maintain battery life. We use it to maintain our summer batteries and winter batteries in the off seasons. Comes with 12 foot reach which is awesome.

Consistent power

MacGyver December 11, 2019

I love the idea of this product and attached it for about a week or so I can say it is holding its own. Here in Kansas we have pretty hard winters and my riding lawnmower seems to struggle the most with the battery maintaining a charge. Usually I end up having to spend time and money trying to get a charge back into the battery before the first mow of spring. This year I am going to keep this maintainer attached the whole winter and see if I still have issues. So far it is great. It is simple to use as it doesn't even allow itself to be hooked up incorrectly. It charges quickly and has indicators to let you know how the charge is holding. There are multiple options that can serve multiple needs. If this works over the winter I will gladly give it two thumbs way up.
