The Last Stand for AA/AAA Battery Gaming Mice? Am I the only one "fighting" against built-in batteries? My G603 is 3 years old, and I just added a 68g ROG Strix Impact 3 (Wireless). Should I buy a third backup?
Exactly! Your G700 experience is exactly why I'm sticking to AA/AAA mice. The freedom of popping in a fresh Eneloop and getting a 'brand new' mouse in 10 seconds is unbeatable. It's sad that modern flagships are taking away this 'user-replaceable' right.

The technical reason replaceable batteries make sense isn't just philosophical.... it's about failure modes. Lithium polymer cells degrade through charge cycles (typically 300-500 before significant capacity loss), and when they're soldered in, the entire mouse becomes e-waste. Your Eneloop NiMH cells maintain \~70% capacity after 2000+ cycles, and the standardization means you're not dependent on manufacturer parts availability.That said, there's a practical middle ground worth considering: the weight penalty. Your 68g Impact 3 setup is actually pretty competitive, but you're still carrying \~11g of AAA + converter vs. \~5g for integrated lithium. For BIFL longevity tracking, I've found Biflly helpful for identifying which gaming peripherals actually survive beyond warranty periods.. they aggregate real ownership data on failure rates and part availability, which matters when you're trying to stockpile.The G304 is probably your best hedge if you want a backup. It's still in production, uses a single AA, and the sensor (HERO) is genuinely competitive at 1000Hz. One spare seems reasonable; hoarding three feels like over-optimization unless you're planning for a 15+ year timeline.

i'm with you on the replaceable battery philosophy - it's why i still use a g304. the market is definitely shifting toward built-in, but there are still options. the logitech g305 (same as g304 in some regions) is still widely available and uses AA. razer deathadder v2 x hyperspeed also takes AA. as for hoarding, i'd get one backup if you're really worried, but not three. technology changes fast - in 5 years there might be better options even if they have built-in batteries. also, eneloops last for hundreds of charges, so your current mice should last many years with proper care.

Looking for a BIFL wireless mouse.
I don't know if it's BIFL, but I've been using my Logitech G604 for many years, and it's still going strong.

I've had this wireless mouse for over 20 years.
For reference, my G603 from Logitech, has had two battery changes (2xAA)since I got it 4 1/2 years ago.

I just bought two 304 mice. One for work and one for home. They are great and cheap.

Best no lag wireless mouse/keyboard
No-lag wireless gaming keyboard and mouse combos do exist, and they’ve improved significantly in recent years. Look for models with 2.4GHz wireless connectivity and low latency response times, specifically designed for gaming. Brands like Logitech (Lightspeed series), Razer, and Corsair offer reliable options that perform on par with wired setups. If you're still unsure, a high-quality wired gaming keyboard and mouse is always a solid alternative for zero input delay.

BIFL - a mouse! What's a high quality mouse I can buy?
I've used a logitech 502 for years no issues yet. The new ones have a cheaper one, feels chintzy, but the higher end one is fine. I just got it for a 2nd computer. Well, maybe a year or two ago, and it's going fine too. Hah, the original 502 I'm speaking of I remembered was a "Call of Duty 2" model. COD2 was released in 2005, so yah, it's been around a while.

Need to replace my mouse!
I'm a huge fan of the Logitech g305. It is ambidextrous minus the side buttons. It is wireless. It wakes up really quickly from sleep just by moving the mouse making it feel like it is always on. It has low enough latency that is even good for competitive games. Uses AA batteries but if you care about weight you can buy a cheap AA to AAA converter. Even with AAA I change the battery every 6 months or so of regular use. There is also a big modding community around this mouse if that's your jam. It is 30 dollars. I've had mine for the past 6 years and it's going strong minus needing new ptfe feet but replacement feet are readily available due to its popularity.
