Here are some useful tips to remember when using and charging batteries:

• Always use the correct battery for the appliance – refer manufacturer’s instructions.
• Always use the correct charger – matched for the battery under charge.
• Always charge batteries and appliances with rechargeable batteries (including phones and laptops) in a safe place – not on or near combustible products (eg like under the duvet where the heat cannot escape) and monitor the charging process.
• Mechanical damage to batteries can cause them to fail – don’t use damaged batteries or batteries that have been exposed to mechanical shock (dropped) – dispose of responsibly. Batteries disposed of incorrectly can cause fires (for example being crushed in a rubbish truck).
• Never charge a phone on the bedside cabinet while you sleep.
