Battery for Light-For-Me Backup Mini Dive light

[fishstix]

I have a Light-For-Me Backup Mini dive light that recommends a 18650 Lithium Ion rechargeable battery. These batteries come in all sorts of configs and size variations. The manual recommends a battery with dimensions no larger than 18.3mm diameter x 65.2mm length. Does anyone out there own one of these lights and can give me a link to the exact type of battery that will work? (Tec Dive where I bought it from is almost useless as far as tech support.)

Here's the complete specs for the light's battery recommended specs:

18650 Li-Ion battery


Characteristics:
• cylindrical lithium-ion cell
• nominal voltage around 3.7V
• positive terminal nub at one end and flat negative terminal at the other
• available with an internal protection circuit to prevent over-discharge and shortcircuit
damage
• for safety reasons recharging requires use of chargers specified for these cells
• dimensions: 18.3mm x 65.2mm (diameter x length) - battery may be 2-3mm longer
if protected, however this length depends on the type of protection
• no memory effect and no scheduled cycling required to prolong the battery's life
• low self-discharge rate of about 5-10% per month
• high capacity
• stable discharge voltage
• high voltage / light weight battery

I know probably a bit late - but I've just ordered these:

Xtar 18650 3.7V, 3100mAh Li-ion Protected Battery

They are a bit longer, but do feature the protective circuitry which the manuals says means they can be 2-3mm longer.

What did you order in the end?
