The battery does not look like a chargeable battery. The UR18650 is a chargeable though.

Cheers..
 
Hello there,

To charge a rechargeable Li battery you need a circuit that
provides a precision voltage with a limited current.

First, you need to find the float charge voltage, which
is usually either 4.1 volts or 4.2 volts. You then
proceed to charge with a limited current, say 750ma,
while you monitor the voltage. When the voltage gets
up to 4.2 volts you stop charging.

If you use a circuit to do this you will notice that
when the voltage gets near 4.2 volts the current starts
to cut back until very little current flows (20ma or so).
This signals the battery is fully charged.

Good luck with your LED circuits,
Al
 
Well...I emailed the people selling them. Those are not rechargeable. /ubbthreads/images/graemlins/frown.gif DAMN!
 
Oh well... That just means I will have a brighter, longer lasting CMG Infinity (albeit an expensive last)...
 
Off topic, but on the same website: some of the price on the lead-acid rechargeable batteries is $0. Also under the miscellanneous category, the power converters from dc-ac for car, are also $0. /ubbthreads/images/graemlins/naughty.gif
