I was given a battery charger with rechargeable batteries as a gift recently and thought how convenient I don’t have to buy batteries each month anymore. Then I did the sums – $5.59 spent on 2 AAA batteries per month x 12 months = $67.08 ($65 is a week of food money to me). The rechargeable batteries will last up to 5 years – a total saving of $335.40 on just 2 batteries. The savings will probably be greater actually when you take into account that what I used to buy will probably increase in price over a 5 year period.
