There are pros and cons to both rechargeable batteries and disposable ones. The former may be more expensive initially, but they will last far longer, making them much more cost effective over time. However, disposable batteries are just that and one will not have to waste time putting their batteries on charge by using this type of battery.
However, we often forget just how important rechargeable power supplies are for the majority of electrical equipment, and from mobile phones to tables, the cost of finding batteries would be very extreme indeed were it not for specific rechargeable options.
However, few people tend to apply this same logic to things such as remote controls simply due to the fact that batteries in such items tend to last a great deal longer than those in the likes of phones. Yet, the main reason is that, for some reason it simply seems far more hassle to take batteries out, put them on charge and the replace them, forgetting that it will be very easy to buy a number of spares and to change them over instantly. In fact, in many ways, using a rechargeable battery in electronic equipment will be far less hassle as you will always have spares at the ready when you need them rather than finding yourself without batteries at a crucial moment.
Of course, you may find that certain items will be used so rarely that they will almost never need the batteries to be recharged and for these types of electronic equipment a normal disposable battery may well be fine. However, for those who wish to save money and ensure that the equipment they use regularly will always have a spare battery at the ready, a rechargeable option will usually make the most sense, and will be a great deal better for the environment at the very same time too.
