It’s more precise than the least expensive product too, which is always a bonus. This is a really inexpensive product that provides the ability to test some of the most common batteries you’ll use around your home. So what is our overall opinion on this product? We’re pretty impressed. It measures just 7.3” wide, 3.5” tall and 1.6” thick so it’ll fit nicely into a drawer whenever you don’t need it. It is a little bigger than the previous product we saw, but it’s still relatively compact. For around 6 USD, that’s peace of mind which most of this product’s competitors just don’t provide. This model comes with a one-year limited warranty. That’s not all that’s great about this battery tester, though. As long as it sits tight between the two terminals, it’ll work.Īll the usual suspects are accounted for: AA, AAA, C, D, and 9V, but this product can also test button batteries like the ones you’d find in a watch. The positive terminal on this product slides up and down to accommodate batteries of almost any size. This makes it one of the best household battery testers around. It’s fairly precise too – the graph has 41 different segments all labeled with either “good”, “low”, or “replace” markers. This saves you from having to throw the battery away, thereby saving you money.
Amprobe says that this is the point where batteries can still be used in low-power devices like TV remote controls. We all know that not all batteries are born equal too, and this tester even accounts for this. The graph is color-coded, green is good, red is bad. The higher the voltage, the further the needle lies to the right. It measures the voltage in the same way, however instead of just telling you the current-voltage it provides context by means of a graph. This product comes with a few enhancements upon the last one, however. When it comes to a product like this, you might wonder what features come with a price-increase of just a few dollars. This battery tester from Amprobe costs around 6 USD, so it’s not the cheapest around. Tests some of the most common battery types.Although it does have a couple of features missing, for the price, it’s difficult to complain.
It’s nice and affordable, plus it tests a good selection of commonly used batteries. In short, this is a fairly decent battery tester.
So what’s our final opinion?Įssentially, this product will be fine for general use around the home or garage, but it lacks the precision required for professional applications. We found that it tended to show lower voltages than the battery actually had. The readings are sometimes a little less accurate than we’d have liked. Secondly, it only displays the battery’s current voltage and won’t tell you if it can maintain that voltage under load. Firstly, there’s no warranty coverage – if it breaks, you’re out of luck. Now, as this product is so inexpensive, there are a couple of concessions that have to be made. You don’t have to worry though: it only uses a tiny fraction of the battery’s power and as a bonus, this means that the tester is always ready to go. This is because it relies on the inserted battery for power. One of the other great things about this battery tester is that it doesn’t require its own battery or power source. Obviously, for larger batteries, this number will be higher. For context, a rechargeable battery is usually around 1.2V fully charged, and a regular one is around 1.5V. This is a good indication that the battery is completely dead. The current-voltage that your battery has is displayed on the 1.25” digital screen, although if it has less than 0.5V remaining, the unit won’t show anything. It has space for a single battery, and can actually test a fairly extensive range of battery types.Īll of your standard battery types are catered for: AA, AAA, C, D, and 9V. It’s 4.2” wide, 2.2” tall and 0.8” thick, so it’s small enough to put in a drawer when not in use. That doesn’t mean it’s a bad product, though: there are actually a few good reasons to buy this model. This product from HDE costs less than 4 USD, so it’s highly affordable. Since a battery tester isn’t likely to be something you use often, it makes sense that the lowest priced product would be popular.
