Typically they're ~20 mA. I just built a mini-keychain flashlight using this battery, one 265,000mcd led (from electronic goldmine) and Sparkfun's LiPo Charger Basic. I used a momentary switch to cut down usage and heat. It will be noticeably dimmer after a dozen or so 20-30 second bursts. The light in theory should continuously discharge for about an hour. In parallel the same LEDs would use double the current and shorten the battery life before charges. If you're going with two LEDs why not step up to the 110mAh battery? I'm going to for my next flashlight. But then I plan on using a bigger LED too!</p>

Charging a 5C with the MAX1555, that most sparkfun chargers seem to use, doesn't seem like a good idea.</p>
