![]() Rated at 2000mAh, we found that these batteries managed an initial result of 2218mAh, and that didn’t change over the full 50 cycles that we put the batteries through. With a starting voltage of 1.4V, these batteries were above the lower limit of 1.2V for rechargeable batteries. In other words, you can charge them today, store them in a cupboard and have them ready for action when you need them. Not only that, but the GP ReCyko Pro 2000mAh AA can hold 70% of a charge after five years. That helps offset the slightly higher asking price, as these batteries will last for longer than the competition. While most will last for around 500 charging cycles, these ones will last for a huge 1500 cyles – three times longer.

In the majority of cases, you will be able to. There are a few products that require the use of alkaline batteries, such as smoke alarms check the manual of the device that you want to use to see if it can be used with rechargeables. That makes rechargeables better for game controllers, toys and even torches. On top of that, rechargeable batteries can deliver more power than their alkaline equivalents, as demonstrated in our performance tests, where we measure the capacity of every battery. However, improvements in technology now mean that there are rechargeables that can compete with alkaline models for longevity. ![]() For example, in remote controls, rechargeable batteries would run out of power at more regular intervals than standard disposable batteries, making them an annoying choice. It used to be that rechargeable batteries suffered from high battery drain, losing a considerable amount of power while sat idle, which made them unsuitable for many jobs. ![]() This varies across chargers depending on a number of factors, like whether they support fast charging.Better for the environment, better value over their life span and, often, more powerful, rechargeable batteries are typically better than their disposable equivalents. They don't dictate how fast your charger will charge a given device. One thing to note here is that milliamp hours are only a measure of capacity. These devices range from hundreds of milliamp hours into the thousands in terms of capacity, but they're all measured the same way. Practically, we see mAh used in any electronic device with a battery, from phones to Bluetooth speakers. A milliamp is a tiny amount of power, so this battery wouldn't be very practical. If that battery can maintain a current output of one milliamp for 1 hour, you could call it a 1 mAh battery.
