Query: One of the worst rechargeable flashlights I have ever owned

We bought this flashlight because we live on a country road and the electricity often goes out in storms and it takes a few hours or longer for the electricity to come back on. After a 20-hour charge- yes, it takes 20 hours to charge it - the spotlight worked for 5 minutes before dimming and finally going out. The flourescent light that is also on the back worked for about 15 minutes after the spotlight stopped working. The instructions warn against letting the battery completely discharge, so we turned it off before the lights completely stopped working. After another 20+ hour recharge, we had the same thing. 20 hours to charge for 5 minutes of bright light, and the spotlight is bright for a good 3-4 minutes before dimming, is just rediculous. Look somewhere else if you want a reliable and long-lasting rechargeable light.
