• 25% remaining: Illuminates red (for 2 seconds)
• 0% remaining: Flashes red (5 times)

Another website is telling me this:

• Red, flashing 5 times: less than 25%
• Red for 2 seconds: 25% – 50%
• Green, flashing 5 times: 50% – 75%
• Green for two seconds: more than 75%

Anyone have any idea which one is correct? For example does the flashing red indicate 0% percent batter life remaining, or less than 25%?

Thanks.
