Compare a Li-Ion battery from 1992 vs now and you are easily talking 2+x recharge cycles that's huge on it's own. But, you also get lower weight, lower volume, increased power, and lower cost. You can even get a vast array of form factors not just little cylinders.

Granted, their are trade-offs and I would love to have 10x the power. Still, 2x energy by weight and 1/3 the cost means I have no problem saying batteries have gotten dramatically better.

Compare the advances in cpu tech or DRAM

How about the advancement in steal or gasoline. Batteries are old tech. CPU advancement is very similar to increases in engine horsepower over the first 80 years which steadily doubled up to rockets and then almost completely stalled out.

Saying it's only they are only 10+x as good in the last 25 years overall is a silly standard. Recharge increase * weight decrease * cost decrease. Remember each of them are independently large improvements.

If you see the same increases happen again electric cars in 25 years would have 1,000+ mile range and charge in ~30 seconds.
