It's simple, I only buy more batteries (except for very moderate kind in playmobil LED lighting uses remotes little biased), as batteries, and Eneloop. Although capacity may seem lower than other brands, curiously they last longer than others! Moreover, this subjective feeling was confirmed by the power charger charger MH-C9000 (bought on amazon) that analyzes the capacity of your batteries. Eneloop batteries all have their initial capacity (within 5%) while the data for other brands fell below 2300 mAh or 1700 mAh 2000. I consider that these batteries are a master purchase, especially with the above cited loader that will load without degrading them.
