How to recharge alkaline batteries using alkaline recharger for low drained devices

Description:
How to recharge regular alkaline batteries with an alkaline battery recharger. The key to success is to not allow the battery to completely drained. Allow 30% or more of power left and charge them for one or two hours. The recharged alkaline batteries can then be used for low drained devices like LED flashlights or calculators. You will need regular alkaline batteries (not every brand will work) and alkaline recharger. I found that non-branded alkaline batteries work best. You will need to experiment with different brand alkaline batteries. So far, I found Sunbeam alkaline batteries are great for recharging but not the Ikea alkaline batteries.
