If you only want high-drain use, then the Duracell Plus AA may be better for you, but if you want batteries in your cupboard for a variety of uses, then these are currently the best choice. However, the high result from the first test, shows that these batteries are a good choice for higher-drain uses, such as toys and batteries. This makes the GP Ultra AA particularly well suited for low-drain uses, such as clocks and remote controls, where power is used more slowly over a longer period. After giving the batteries time to cool down, we re-ran the test and found they could deliver another 378.25mAh. First, we had the initial drain result, which showed that the batteries held 1302.25mAh, which puts these batteries close to the top in our tests. This result was delivered from two results. These batteries delivered a total capacity of 1680.5mAh in our tests, which is the highest that we’ve ever seen. Our reviews below explain everything.Īccording to our tests, if you’re looking for flexibility and overall power, then the GP Ultra AA batteries are the best that you can currently get. We also consider price: sometimes cheaper batteries are a better investment despite having lower power. We also take into account the use a battery may be put to: high drain (for devices that use a lot of power quickly, such as toys and torches) or low drain (for devices that use a little bit of power irregularly, such as remote controls). This allows us to give more accurate results than, say, using a toy car or torch to measure how long a cell lasts. We test all of our batteries for total capacity, using a dedicated battery tester. There are some devices that require alkaline batteries, such as smoke alarms. This makes them particularly well suited to remote controls, where you only use a tiny amount of power when you hit a button you then don’t lose power while the remote sits unused. And, unlike rechargeable models, they don’t lose charge while they’re sat dormant, so they’re always ready to go. Here, we’re rounding up the best alkaline batteries in both AA and AAA sizes.Īlkaline batteries, such as these, are all designed to have a shelf life of ten years or longer. Operating temperatures from -4☏ to 129.2☏.While rechargeable batteries may be able to cope with most tasks, nothing can beat the convenience of a set of pre-charged AA and AAA batteries.
