Anyone with a green bone in their body should love rechargeable batteries, but itâ€™s awfully difficult. Alkaline batteries provide always available power, last a long time, and are widely available and inexpensive, while rechargeables are expensive, unpredictable, and usually dead when you need them. As a fan of green technology, I was frustrated at the prospect of buying throwaway alkaline batteries, but could not find a better solution until now. The La Crosse BC-700 battery charger has reversed my impression of rechargeable batteries. Itâ€™s that good.
