Do Rechargeable Batteries Really Save You Money?

A lot of people in Australia perceive that rechargeable batteries are more cost-effective than the regular alkaline ones. But can you really save money on rechargeable batteries?

Check your battery needs

If you have devices, or smart gadgets that needs a battery change every 30 to 60 days, then you might want to opt for rechargeable batteries.

For environmental reasons, throwing alkaline batteries are incredibly hazardous. Rechargeable batteries are a great alternative that can reduce toxic waste costs by disposable alkaline. But if you consider the price and the usage of your battery needs, rechargeable batteries may not be financially sensible at all.

Here are some factors you should take into consideration before you switch from disposable batteries to rechargeable batteries.

What are your battery needs?

Look at things in your house that needs batteries. Your wall clocks, TV remotes, flashlights, smoke detectors, and etc. These devices don’t use much energy and they don’t demand battery change regularly. It would take you years to overcome the payback period if you decide to use rechargeable batteries. But if you have devices, or smart gadgets that needs a battery change every 30 to 60 days, then you might want to opt for rechargeable batteries.

How much is the cost of normal batteries vs rechargeable batteries?

The average cost of a 4 pack rechargeable batteries ranges from $15 to $20 depending on the brand, and type (NiMH, NiCad, rechargeable alkaline, or lithium ion). For a battery charger, you will need to shell out $22 for it. On the other hand, disposable alkaline costs only $5 per 4 pack. So if you do the math, you will manage to save about $15 with a disposable one, and save $22 from a charger and electricity bill that the charger will consume.

When to use rechargeable batteries?

Most of the time children’s electronic toys in Australia consumes the most batteries since they don’t often come with an AC adapter. It’s impossible to power them without batteries! For a more energy-efficient choice, rechargeable batteries are a great alternative. Just invest in a good charger to lengthen the life of your rechargeable batteries. They should manage to hold a charge up to 500-800 charge cycles.

How much money will you save on rechargeable batteries?

Your savings on rechargeable batteries may vary for each household. But here’s an example: You use 12 batteries each month, which adds up to 144 batteries a year. For a traditional battery you can spend about $114 to $240 per year (depends whether you buy in bulk or not). With a rechargeable battery you will spend $53 for 12 rechargeable batteries and $22 on the charger with 4 batteries already included, amounting to a total of $75. Your investment will return after a year, and you can save at least $39 to $165.


If you have appliances or devices at home that drains batteries very quickly, rechargeable batteries are highly recommended to save money. But if you only have basic needs for batteries, this may not be cost-effective as your investment will not return very fast as you expected to.
