There is a simple trick for bringing your dead batteries back to life. A dead battery is not a simply empty battery, but a battery that is either not rechargeable, or has been recharged so many times that it does not hold the electricity anymore.
The following video shows you how to do it:
Explanation: Rechargeable batteries create a crystalline matrix over time, which makes further recharging close to impossible. The initial step of the charge sequence is of high power, therefore repeating this step over and over breaks up the crystalline matrix and makes the battery chargeable again. No need to buy a new battery – safe money and use your old ones longer!
Let’s skip these uncommon batteries and focus on batteries everyone uses. For normal household batteries, a very good financial decision is buying rechargeable batteries. These are more expensive initially, and you have to buy a recharge device, but after just a few years the price has been paid for by the recharging capability, and you’re saving money every day you use your batteries.
To make the huge impact clear, here a quick math example:
An average household uses 60 standard AA batteries a year.
Cost = around $50 / year
So over a time of 10 years, you’ll be spending $500 on batteries!
If instead you buy rechargeable batteries:
Cost = around $100 for batteries + $50 for the charger, one time
Each following year the electricity costs for the rechargeable batteries is minuscle, so the only costs are the $150 in the firs year.
After 3 years, both choices have cost you $150.
After the full 10 years, the rechargeable batteries have cost you $150 still, while the normal batteries have cost you $500 – a loss of $350 if you’re making the financially bad choice of buying normal batteries.
The Financial Future Advice is therefore to invest into the rechargeable batteries – it’s a smart investment.
