You will get 2 hours of recording time (photos or automatic photo mode) out of the Standard Definition HERO camera in mild and warmer temperatures with LITHIUM or Rechargeable NiMH battery types. Alkaline are not recommended for extended use in GoPro cameras as their battery life is very short and they suffer voltage drop (failure) from vibration.

IN COLD WEATHER use LITHIUM batteries to maximize recording time…they do not lose voltage as quickly as the other battery types. In 15 degree Fahrenheit temps you can expect 1 hour of recording time…so half the normal amount of recording time.
