You will need
- - the appliance is powered
- - a store that sells batteries
To the appliance has earned, first find out which type of battery is right for them. This information can be found on the packaging of the device or in the attached instructions. Buy the batteries of the required type in a specialty store.
Salt batteries are typically used for devices with low power consumption, small toys and flashlights, various low-power remotes. Alkaline (alkaline) batteries can supply the required power to the radios, table clock, shavers, toys motor, audio player.
For calculators, watches, hearing AIDS are suitable silver-zinc batteries. The lithium current sources with the largest capacity, used in various information storage devices, cell phones, watches, various devices with high power consumption.
To get full information about battery allows labeling. In the notation LR20, LR14, LR6, LR03, the First letter indicates the chemical composition of the battery: "C" - ion, "S" for silver-zinc "L" - base. If the letter is missing, then you have a salt battery.
The second letter indicates the shape of the power source: R - cylindrical, F - flat, in the form of tablets. If the marking of the batteries starts not with letters and numbers (e.g. 6F22), it means the number of its components smaller batteries. The numbers at the end of such designations indicate the radius of the batteries.
In the instructions to the electrical device find out, where is the compartment for the batteries. Slide the right cover and carefully inspect it: on the inner side can be placed layout of batteries in the compartment.
At one end of the cylindrical battery is the negative terminal and the other positive. The positive pole of the convex portion is larger than the negative. Also usually on the housing of the power element can be detected symbols in the form of plus and minus, indicating the polarity of the poles.
The size of the cylindrical batteries are of the following types: D, C, AA, AAA. D - battery of large diameter, AAA is the smallest.
Batteries-tablets, on the contrary, the positive terminal is on the flat side, and negative to slightly convex. Usually on the flat side of the batteries you can see the marking in the form of a plus sign showing the polarity.
Insert the batteries according to the diagram on the cover of the device or clarification in the instructions to the device. Be sure to observe the polarity of the poles on the batteries and the circuit.
After placing your batteries in a special compartment close the cover of the device.
In one appliance, insert the batteries, same manufacturer, same type and the same state of charge.
Advice 2: How to charge the batteries
Not necessarily every time you get the batteries, take the time to buy a new one. Much easier to spend a little more money and purchase the batteries that you can charge.
To charge batteries you need a charger that is often sold together with two to four batteries, so if you bought the kit, half the problem is already solved. If the charger, then they will have to acquire.
If you decided on buying the charger at the same time, check your existing batteries – not all can charge. On rechargeable batteries Rechargeable will necessarily be written and large numbers indicated their capacity: 800, 1200, 1600, 2200, 2600 etc. If your batteries such signs there, and a voltage of 1.2 V and 1.5 V – be sure to charge those batteries is impossible.
After the batteries and charger ready insert the battery into the device, strictly observing polarity. Look for signs of the plus and minus buttons and insert the batteries accordingly. As a rule, to insert the battery in the charger need to bend the "tongue", which will hold the battery by means of a spring.
Making sure the battery is securely in the charger, insert it into the socket. On most chargers the LEDs at this point, turn to red, which means the beginning of the charging process.
All batteries can one find information about how many hours to charge these batteries. For batteries of different capacity, charging time can vary from 12 to 24 h or more. In addition, some of the charger signals completion of the charging process a sound signal or a change in the color indicator from red to green.
Types Of "Batteries". Battery chargers, providing a constant voltage (potentiostatic charge mode) and a combined charge. Charger for lead-acid, lithium-ion and lithium-polymer batteries are supposed to regulate current at the first stage of the charge and stabilization of the supply voltage at the second.
