The rate at which self-discharge in a battery occurs is dependent on a range of factors such as the type of battery, state of charge, charging current and ambient temperature.

Self-discharge decreases the shelf-life of batteries and causes them to initially have less than a full charge when actually put to use. Self-discharge is an occurrence in rechargeable batteries in which internal chemical reactions reduce the stored charge of the battery without any connection between the electrodes i.e. What is ‘self-discharge’ of a rechargeable battery? However, standard rechargeable batteries do not have this feature so they will need an initial first charge before use.Ĭ. If your rechargeable batteries state they are "Pre-Charged" or "Ready to Use" they can be used straight from the pack just like single-use batteries. Can I use my rechargeable batteries straight from the pack? There may be some devices where rechargeable batteries may not be suitable, for example some brands of DAB radios where four or six batteries are used in series, and the voltage difference between NiMh rechargeable batteries and standard alkaline batteries can cause poor performance.ī. The main benefits are that after the initial investment they will save you money as you can reuse those batteries hundreds of times and they have the added benefit of helping the environment by saving raw materials and avoiding the waste of single-use batteries which may eventually end up in land-fill. In most situations, nickel metal hydride (NiMH) batteries can replace (single-use) primary batteries, especially for high drain electronic devices.
