GOOD HOUSEKEEPING UK HAS BEEN QUOTED AS SAYING THAT YOU SHOULDN’T USE RECHARGABLES IN SMOKE ALARMS. IS THIS CORRECT?

Good Housekeeping rationale: “when rechargeable batteries run out of power, they do so very quickly, whereas disposable alkaline batteries tend to ‘die’ slowly. This means you won’t get the warning beeps that tell you when the battery in your smoke alarm needs changing if you use rechargeables.” Due to its safety nature, the smoke alarm is not an ideal device for standard rechargeable batteries. Indeed standard rechargeable batteries discharge with time, and this means that for essential safety devices such as a smoke alarm, it is not recommended. We also need to remember that even if disposable batteries are used in smoke alarms, it is highly recommended to change the battery a minimum of once a year. Still can’t find what you’re looking for?

IS IT OK TO USE RECHARGEABLE BATTERIES IN ANY DEVICE?

You can use round cell rechargeable in absolutely any device where you would normally use an alkaline battery, unless stated otherwise by the device manufacturer. There are no interference implications using rechargeable battery brands that are different to the device brand. (Please note that this is referring to round cell rechargeables, the lithium different shaped batteries are often developed by the manufacturer specifically to fit a certain cavity size, and therefore only the brand battery might work).

WHY DO CHARGERS LIST A “RANGE” OF TIME WHEN EXPLAINING THEIR CHARGE TIME?

When a charger lists a range of charge time, it refers to the time it takes to charge a lower mAh cell. For example, a AAA cell will typically have a lower mAh capacity rating than a AA cell and will therefore require less time to charge.
