Most people who need a new battery will automatically think "I know, I'll go to Halfords".
For your sake, don't. Batteries from Halfords are double the price of the same battery that
can be bought at a local motor factors. Either look in the Yellow pages (if that even still
exists) or search for a motor factors in your area on Google.
The Right Battery
Fortwo
Finding the right battery for a Fortwo isn't as easy as getting one that will fit that matches
the specifications above. There is one very important factor to take into account.
Battery gas venting
When a standard car battery is charged via the alternator, it creates hydrogen gas.
In standard cars, that battery is under the bonnet so the gas drifts away.
In the Fortwo, the gas could accumulate in the cabin causing an explosion hazard.
The standard Fortwo battery comes with a venting tube that exits the bottom of the battery tray, your replacement should have this connection unless using a sealed Optima battery.
Roadster
Any 063 type battery will be fine, the battery doesn't need the vent pipe like the fortwo.
Forfour
Any 063 (petrol engine) or 027 (diesel engine) battery will be OK for the Forfour.
Where Is The Battery?
Right Hand Drive (RHD)
There are 2 big plastic retaining nuts that twist off by hand at the top and bottom.
Remove the foot rest by taking it sideways out of the car, it can be awkward.
Left Hand Drive (LHD)
Open the passenger's door and slide the seat all the back (well, as far as it will go with all that junk behind it). Pull the carpet back to reveal the polystyrene foot rest block.
