GODP Rechargeable Battery Review (AAs rated at 300 mAh)

If you’re visiting this page than you’re probably wondering how good are the GODP (Good Power) Rechargeable Batteries.

We were wondering the same thing so we recently bought a few dozen from Ebay for our photography needs and put them to the test.   Keep in mind no scientific equipment was used in this test and we recorded only real life results when used in a photography flash application.  However, we thought this would be useful to a lot of people.  All tests were performed with the currently top of the line Canon 580 EX II.

We compared the GODP AA batteries to two other types of batteries that we currently own:

Ultra Pro Rechargable NiMH AA – 2500 mAh ratinng
Sanyo Eneloop Low Discharge NiHM – 1900 mAh rating

GODP AA batteries are also NiMH and are rated at a staggering 3000 mAh

So let’s put them to the test.

The first thing that we noticed upon opening these batteries is just how light they are.  Weighing them and the other two batteries we found out the below:

 

Battery Type	Weight (grams)
UltraPro	108
Eneloop	94
GODP	67

Now, if you consider the power rating, it appears that the GODP have a MUCH higher power density (power per unit of weight).  More than twice that of the Eneloop and almost twice that of the UltraPro. Considering that all NiMH batteries are esentially made from the same material, this is very suspicious.

	grams	mAh	mAh/g
UltraPro	108	2500	23
Eneloop	94	1900	20
GODP	67	3000	45

In the past we measured the number of ‘full power’ flashes we get with both the Eneloops and the Ultras. This is the data we had from the past:

	mAh	Full Power Flashes Actual
UltraPro	2500	173
Eneloop	1900	161

Thus, given the ‘claimed’ power rating of the GODP AAs, we estimated the number of full power flashes we were expecting:

	mAh	Full Power Flashes Actual	Expected Full Power Flashes
UltraPro	2500	173	173
Eneloop	1900	161	161
GODP	3000		250

Now let’s see, how these batteries performed in this real life test:

	mAh	Expected Full Power Flashes	Actual Full Power Flashes
UltraPro	2500	173	173
Eneloop	1900	161	161
GODP	3000	250	43

 

That is roughly only 17% of the expected performance.  THUS to extrapolate the “ACTUAL” mAh rating of these batteries, we can estimate, they are performing more as if they were 520 mAh!!  

To summarize:

GODP AA Claimed mAh Rating: 3000 mAh
GODP AA Actual real life performance: approximately 520 mAh

STAY AWAY FROM THESE BATTERIES.  This appears to be a BIG fraud.

PS.  After doing this test a few times to ensure we were not misrepresenting reality the actual number of full power flashes we got from the GODP batteries actually started to DROP, far below the original 43 full power flashes.  Truly BAD!
