Winmax AA スーパーアルカリ電池 - スーパーアルカリ電池 - AA 4本

My kid's RC car used to slow to a crawl within twenty minutes on heavy duty cells, but these have kept it running full speed through a whole afternoon. Alkaline is the right call for anything with a motor.

Swapped these into my kid's ride-on toy and it runs a full afternoon without the slowdown I used to get. Alkaline really does hold up better under load than the heavy-duty ones.

The RC car was eating heavy-duty batteries in one afternoon, so I switched to these alkaline ones and it now runs a solid two hours per charge. Four in a pack is handy for keeping a spare set ready.
