How to insert the batteries

Flashlight, a radio, a watch able to operate autonomously for a long time even where there is no electricity, thanks to the batteries. The capacity of these food elements depends on their type and material content. Sometimes devices that are powered from independent sources of electricity are sold without them. In order to use the purchased appliance you need to know which batteries fit for him and how to properly insert the device.

You will need

• - the appliance is powered
• - a store that sells batteries

Instruction

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. The size of the cylindrical batteries are of the following types: D, C, AA, AAA. D - battery of large diameter, AAA is the smallest.
9. 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.
10. 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.
11. After placing your batteries in a special compartment close the cover of the device.
