We mention primary and secondary batteries regularly in our blog posts, as if assuming our readers know how to compare them. So we thought it was time for a refresher course on the primary and secondary battery difference. Choosing between these two battery types is important, so let’s get started!
Two Main Types of Batteries in the Stores
The Purpose and Role of Single Use Batteries
Disposable batteries produce energy through a chemical reaction. We can only use a primary battery once, because we cannot recharge it safely. Single-use batteries are relatively cheap, although their voltage is low.
This makes them ideal for simple, low voltage devices we use for short periods. Here we think of remote controls for televisions, etc. We need to keep a supply of spares though, because used primary batteries can suddenly stop working.
The Difference That Secondary Batteries Make
Secondary batteries are rechargeable, using an external current that restores their energy. Although we may need to purchase a separate charger, depending on the particular application.
The primary and secondary battery difference has become more marked with powerful lithium batteries. These rechargeable batteries power indispensable devices, including our laptops and phones.
Other Factors May Affect Our Purchasing Decision
Primary batteries store well without losing significant energy. Secondary batteries, on the other hand, drain even if we are not using them. We add a small amount to our utility bill, every time we top up rechargeable batteries.
So much for the operating costs. We also have a capital outlay that can affect our budget and cash flow. Single use batteries are cheaper, which makes them popular. However, rechargeable ones may work out less expensive in the long run.
But there is a softer side to this discussion, that may add to the primary and secondary battery difference in our minds. We may discard more single use batteries than rechargeable ones this year. Secondary batteries are simply, more environmentally friendly.
