The supermarket is to offer Freepost envelopes in its stores nationwide from November that will enable customers to send their old batteries off for recycling.
The retailer expects that 2,500 tonnes of batteries will be saved from going to landfill every year.
It is also offering a mobile phone and inkjet printer cartridge recycling service.
Sainsburys recycling manager James McKechnie said: Our customers are recycling more and more but we want to make it easier for them. This is a major green step forward because we are extending the amount that people can recycle. Most people now use either a mobile phone, an inkjet printer or in the very least batteries, so we know this will be something people will be able to use that is of benefit to the environment.
Waste & Resources Action Programme (WRAP) manager local authority relations Chris Davey said: As the manager responsible for WRAPs battery programme, I am pleased that Sainsburys are introducing a new collection scheme for batteries as well as mobile phones and inkjet cartridges.
If the UK is to meet the new challenging recycling targets for batteries, then we need to try a wide range of different collection schemes.
Comic Relief will benefit from the scheme by receiving £3 for every mobile phone recycled and 50p for every inkjet printer cartridge.
