for a game controller they are more than suitable. The technology has also improved drastically since the 90s.

The IKEA Ladda 2450 mAh batteries are actually the same as Eneloops for a fraction of the price. IKEA’s charger is also very good and uses the hybrid approach for quick charging and taking them to max capacity. I use them in all my game controllers and they work great.

I actually don’t support game controllers with internal lithium batteries. They will wear out overtime and are harder to replace.
