However there are some exceptions where the difference in voltage can cause poor performance. This means that in the vast majority of devices the voltage should not be an issue when replacing single-use batteries with rechargeable batteries. The major difference is that single-use batteries output 1.5 volts when first used and end below 1.0 volts, whilst rechargeable NiMH batteries maintain an average of 1.2 volts for most of the time. So throughout the time the batteries are used, single-use batteries’ average output is 1.2 volts, similar to that of rechargeable NiMH batteries. The exception being PP3 9 volt block size battery, and some specialist security batteries, which can be higher depending on the size and type of battery.Īs single-use batteries are consumed, the voltage reduces. Standard size single-use batteries usually have a nominal voltage of 1.5 volts whilst rechargeable batteries are 1.2 volts. RETURN TO TOP What is the difference in voltage between rechargeable batteries and single-use batteries? See the FAQ on voltage for more information. 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. 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. RETURN TO TOP Can I use rechargeable batteries in devices that use single-use or alkaline batteries? Common rechargeable battery types include nickel metal hydride (NiMH), nickel cadmium (NiCd) and lithium ion (Li-ion) batteries. Rechargeable batteries can be recharged and reused from 500 to 1000 times depending on usage. Common primary battery types include alkaline, carbon zinc, lithium, silver oxide and zinc air batteries. Single use batteries (also known as primary batteries) are the same as disposable batteries, which are designed not to be recharged and have to be discarded when flat (or discharged).
