Want to use rechargeable batteries to be more environmentally friendly and save money? Here are the 'do's' and 'don'ts'.
You can use rechargeable batteries instead of cylindrical alkaline batteries (such as AA or C) in most gadgets.
If in doubt, check the instruction manual or contact the manufacturer.
Never use them in smoke alarms or detectors, as when rechargeables are not in use (or just a small amount of power is being used) they discharge stored power.
For the same reason, it is better to use alkaline batteries in devices that are not very power-hungry, such as remote controls.
Alternatively you can buy low-discharge rechargeable batteries which hold their charge for longer.
