- Never carry loose cells – they should be suitably cased at all times when not in use. (We supply free cases with every order)
- Do not short batteries with metallic objects.
- Always use a battery charger designed for the cells you are charging. You can find ours here
- Never leave a battery charger unattended.
- Never completely discharge batteries. (The cut off for most cells is 2.8v or 2.5v)
- Check your wraps and insulators regularly. Replace worn or damaged wraps before continuing use. You can see our selection here
- Do not expose to extreme heat or cold or sudden fluctuations between the two.
- Always dispose of end of life cells at your local WEEE recycling centre or return them to us for free disposal.
We hold the MSDS (Material Safety Data Sheet) and UN38.3 (UN Transport Testing) and data sheet files for all cells we stock. Please ask if you would like them emailed or included with your order. Please bear in mind that the Data Sheet information is presented in factory format and aimed at accumulator/battery pack builders.

Purchased through eBay and was thoroughly impressed. Having bought a 40T previously through a different vendor, i proceeded to compare them! The 18650.co.uk Samsung 40T was better offering up to 25% more battery life!! Outstanding.
Finally i would like to say how clever it is printing the sellers details on the battery. No mistaking which is which. Don’t know if this is the case with 18650’s, will have to order some & find out!!
