Unlike batteries, rechargeable accumulators are a reusable power source. When the accumulators sit down, they can be recharged and reused using a special charger. Magic!
Payback of accumulators
Of course, accumulators are more expensive than conventional batteries. But they save energy for a long time and support up to five hundred repeated recharges. The figure is impressive! This means that in fact, by purchasing one accumulator, you will immediately acquire 500 batteries of the same capacity, unless, of course, you take into account the cost of electricity needed to recharge the battery.
Battery Features
Batteries differ in the following parameters:
type - there are two main types of batteries: nickel-metal hydride (Ni-MH), lithium-ion (Li-ion). Without going into technical details, let's just say that the latter type is the most popular because such batteries can be recharged without waiting for a full discharge, hence their service life is longer than for Ni-MH batteries.
Capacity - the amount of electricity that can store the battery. The higher the capacity, the less often you need to recharge the battery. The most common are batteries with a capacity of 1,300 - 2,700 mА / h and 650 - 850 mА / h. How can I calculate the battery life on a single charge? Divide this value by the current that your device consumes. For example, the battery capacity is 2 000 mA / h, and the current consumption is 100 mA / h, therefore, the battery will last about 20 hours.
size - there is a marking of sizes: AA ("finger"), AAA ("little fingers"), C, D, 9V. These symbols can be found on the battery case, but easier to navigate in appearance: rechargeable batteries have the same dimensions as the batteries.
How correctly to load?
To charge the batteries, you must separately purchase a charger that can be plugged into a standard 220 V outlet. Chargers differ in how much current they pass through. It is necessary that the current of the charger is approximately 1/10 of the capacity of the battery. It is useful to charge the batteries for a long time for 12 hours. Fast charging, as a rule, shortens battery life, and in some cases it is unsafe. If the battery does not support fast charging, it is better not to try to increase the charging current - the battery may explode.
When you need batteries
In devices that are characterized by low power consumption, for example, in watches, remote controls, it is better to use conventional batteries. Their service life is long enough and, from the point of view of the economy, it will be reasonable. Why buy an expensive battery pack with a charger, if you can take the batteries that will last 2-3 years? And, of course, tourists cannot do without batteries. Do not charge the same in hotels batteries? And in the mountains and forests, this possibility will not be presented at all.
In devices with high energy consumption, for example, in cameras, flashes, it is more rational to use accumulators than to constantly buy battery kits (A accumulator with a capacity of 2700 mA / h will make about 1,500 pictures!)
