GODP Rechargeable Battery Review (AAs rated at 3000 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.

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

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!

Thanks to the web and this site for posting something I had now found out for myself the hard way. I wish I took a look at Google to find this site before hand. I support the comments since they are correct with regards to the energy density and performance. Can't take nothing at face value, must do the home work before making a purchase. Very nice, and lesson learned to do review searches on products prior to spending your hard earned money on deceptive marketing and false leaders on the web..

Recently, I bought a DC 12300, a 12V battery with high capacity 3000mAh and I got a charger 12.6V and 500mA output. First thing I did when I got the battery, I measured its voltage and it was 2V. After 6 hours of charging, (I presumed that it was 3000mAh-6 hours of charging). I got the same result. So I disassembled the battery and I saw 3 smaller batteries which were connected in series. The total capacitance is equal to the capacitance of one smaller battery 1380mAh. If the smaller batteries where connected in parallel the capacitance where triple (1380mAh*3). I also noticed that the samaller batteries where not balanced. I measured the voltage of each smaller battery and I got 3.7V and 0V for 2 others smaller batteries.

Telling lies is one of the most common traits of China origin businesses and as well government.
There is no such thing like ethics or shame for those chinese people. They are absolutely greedy to be reach fastest way and there is no limit to for it. Even branded products made in china comes with serious flaws, Even if products seems ok initially, it will create different complication along the way, Most china origin products have excessive toxic ingredients which causes serious health problems. Most chinese products labels lie, even simple QC checked labels usually false, They have been skipped to decrease the cost. Batteries wise its true personally i have tested many of them and found no integrity, Even GP batteries which supposed to be better, have serious issues. Most GP batteries dies before before completing less than half of claimed life cycles, not to mention leak and other problems. GP batteries now made by crappy chinese 3rd party manufacturers Maximum performance so far i found around 78% of its claimed capacity but usually below 60% of actual capacity.

China is Cancer to mankind
