To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought this at the end of April and replaced my GBA's original battery and the new battery would last about 45 minutes on a full charge, so I wrote a original review talking about how mediocre this product is and I put my GBA on a shelf to collect dust.
Less that 5 months later, I buy some games at a yard sale and put my GBA on the charger and this SAME battery is lasting about 45 SECONDS on a full charge; a new battery should not be in this state after this amount of time.
The product pictured is a KMD brand replacement battery. Instead i received an extremely cheap looking Tomee battery, a company known for making shoddy replacement batteries for everything from Xbox controllers to 3DS's.
The battery doesn't work. Out-of-the-box it provided no power to the Gameboy. Charged it overnight (the charging indicator light did turn on). Still no power! How do you make a battery that doesn't do anything?!!! I filed to replace the battery with another, but all Amazon can do is give me my money back. Waste of time and waste of money.
Purchased to replace my GBA SP battery (which is starting to bulge with age) and was severely disappointed when the battery, once inserted, took away my systems ability to turn on. The batteries are the same size, but this one is MUCH lighter. Almost as if it's just a piece of plastic with two metal pieces on it to make it look like a battery.
Did include a screwdriver that worked as it should have....but didn't make my purchase for a screwdriver.
Didn't really expect to receive what was pictured, as the description says packaging may vary. However, everything else says 600mAh. The product received was 400mAh, this is borderline false advertisement. I get the fact that packaging may vary, but product may vary would have been a more accurate description. Returning and not buying from this seller again.
Cheap junk battery. What I received wasn't what was pictured. I received a no name battery that appeared to be of lower quality. The battery wouldn't charge in either of my GBA SP systems. I even tried using different chargers. However my ten year old original GBA batteries charge up just fine.
Most likely just got a bad battery, but still pretty shoddy. Also, after looking at some other reviews it turns out that this battery failing very early isn’t uncommon, so I strongly recommned looking elsewhere to revive your GBA SP as it probably won’t last long...
The battery I recieved was turquoise in color, which is different from the item picture. The battery charges for a short moment, and won't turn on. I checked the gameboy sp for faults, and found none. Simply the battery does not work.
