Using rechargeable camera batteries in your camera is a great way to get the best value for money. These batteries can be used over and over again; some of the best types out there can be used hundreds of times. The biggest difference in quality is due to how long the batteries will last before each recharge and how many recharges you can get out of them before they will no longer work. There are three main types of rechargeable camera batteries on the market today. Below is a small summary about each type.
Nickel-Cadmium Rechargeable Camera Batteries (NiCd)
This type of battery was very popular for a long period of time because they were long lasting and easily recharged. Compared to other types of batteries that were on the market these were relatively cheap and more cost effective than other types of batteries. One of the biggest disadvantages of nickel cadmium rechargeable batteries is that they have a memory. This means that if the battery is constantly recharged but not fully, it would then eventually only ever be able to hold that amount of charge. For example, if you only recharged your nickel-cadmium batteries to about 70% many times, when you try to recharge them to full they will not. Another big disadvantage of these batteries is that they are highly toxic and quite difficult to manufacture.
