minmao Posted September 29, 2021 Share Posted September 29, 2021 I just found out that the battery of my atgames genesis handheld become a little swollen. I searched online and could not find any replacement except some expired ebay listings. Is there specific model number I could search for? Thanks!

towmater Posted September 30, 2021 Share Posted September 30, 2021 aren't they generic versions of Nokia BP-somethings? Quote Link to comment Share on other sites More sharing options...

towmater Posted October 20, 2021 Share Posted October 20, 2021 Backtracking, the batts of the same model number on Amazon look physically different, sorry. Now I need to find one as well. Quote Link to comment Share on other sites More sharing options...

Now I need to find one as well. Found one battery could work. Canon NB-5L. The size is smaller and thicker, but the contacts fits perfect. I found this in one of the comments on this page. Some foam pieces solved the size problem. https://www.instructables.com/Upgrade-an-ATGAMES-Sega-Genesis-Portable-Battery-W/ Edited November 26, 2021 by minmao 1 1 Quote Link to comment Share on other sites More sharing options...

The batteries in that post are $35 when I looked them up, almost as much as I paid for the portable itself! I have 2 Sega portables and one atari. One of the Sega ones the battery was swollen and had to go. The Atari one appears it might be at the start of that process. Quote Link to comment Share on other sites More sharing options...

RodLightning Posted April 29, 2022 Share Posted April 29, 2022 I used a battery made for Samsung digital cameras. Search ebay or Amazon for SLB-10A. The battery is a little small for the atgames genesis battery compartment, but can be padded on the end and sides to help hold it in place. I used a bit of cut packing foam. The important part is that the contacts line up correctly. They sell for around $7 to $10 USD. I read somewhere online (forget where) years ago someone claiming that the game unit will drain the battery too low to the point of destruction. Being a cheap design, it lacks any protection to keep this from happening. No idea if this is true, but I have since stored mine with the battery removed.

These batteries seem to go fast. Quote Link to comment Share on other sites More sharing options...
RodLightning Posted April 30, 2022 Share Posted April 30, 2022 Here's a picture of mine, with a SLB-10A camera battery installed. The block of packing foam is wrapped in green tape and wedged behind the battery. There are three contacts on the other end that are springy enough to keep the battery in place. When the back is on it and screwed down, it all holds together well. 1 Quote Link to comment Share on other sites More sharing options...

Can the NB-6L battery or SLB10A battery be charged inside the flashback or does it need to be charged in the charger made for the battery specifically?

The flashback charges either battery when it is plugged in. I don't think there is any overcharge protection though, so I wouldn't leave it plugged in too long after the battery is full.

Yoda Dafoe Posted September 9 Share Posted September 9 I got the Sega version (new) and the battery bloated up after only about 3 months of use. It's also scary. A bloated lithium battery is no joke. This is really good information, thanks. Quote Link to comment Share on other sites More sharing options...
