Capacity is Overrated
on March 13, 2013
After a trip to Tahoe, it felt like the Wasabi batteries crapped out sooner than my original GoPro battery. That prompted an investigation.
I charged the original GoPro battery and the 2 Wasabi batteries on the Wasabi charger. The wasabi charger is pretty consistent - the batteries were coming off the charger at 4.17V, which is a full charge for li-ion.
I discharged each battery at a constant 0.4 amp rate on a battery discharger with a cutoff set to 2.8V. Why 0.4 amps? I discharge at approximately the same rate as the battery is being used and a 0.4 amp discharge would dump the battery in a little over 2 hours.
People are raving about the 1200 mAh capacity on the Wasabi battery label. It's a flat out lie.
They tested at 856 mAh on one and 862 mAh on the other battery. That's only 72% of the rated capacity. FAIL!
The GoPro battery tested at 937 mAH - which is significantly more capacity than the Wasabi batteries.
-1 star for inferior capacity
-1 another star for blatantly lying about it so that unsuspecting people would buy it.
