At check and battery service it is necessary to observe special safety measures. In battery banks always there is at the higher measure an inflammable hydrogen, therefore approach to a place of work with the lighted cigarette, and any sources of open fire is inadmissible. Work only неискрообразующим as the tool. The battery electrolit represents a solution of sulfuric acid and its hit in eyes and on open sites of a body is fraught with serious traumas. Besides, the electrolit easily destroys a fabric of clothes and a paint of panels of a body of the car. At a detachment from the battery of wires always begin with the negative. To connect it follows, on the contrary, to the last.

Check up an external condition of the battery. If the positive plug of the battery and it клеммный a clip on your car are equipped by a rubber protector, check up it on presence of cuts and other damages. The protector should cover completely the plug together with a clip. Check up clips on reliability of fastening on plugs and presence of signs of corrosion. The case and a battery cover should not have cracks. The battery should fasten reliably on the pallet clamping laths. Check up both wires of the battery on all their length on presence of cracks and протертостей isolation. If during external survey of the battery corrosion traces are found out (in particular around an arrangement of plugs) which represent fragile white colour a crust, the battery should be removed for cleaning carrying out. A key ослабьте bolts клеммных clips - remember that by the first the negative wire should be disconnected - and remove clips from plugs. Then give fixture (a bolt with a nut) a clamping lath, remove a lath and take the battery from an impellent compartment. Carefully smooth out клеммные clips of wires one of special adaptations (see an illustration) and wipe their solution of baking soda. The same solution wash out plugs in the top part of a casing of the battery, however, watch, that the solution has not got in the battery. Cleaning spend in goggles and rubber gloves in order to avoid hit of splashes of a solution to eyes and on open sites of hands. The clothes should be dressed such that after it was not a pity to throw out it - splashes of the solution mixed with acid will lead to formation in a fabric of holes. If degree of corrosion of plugs is too great, preliminary smooth out plugs the special adaptation (point 7 see an illustration). Carefully rinse all smoothed out surfaces with pure fresh water.

Check up a condition of the pallet of the battery and bolts of clamping laths. If the battery is removed from the pallet, track, that at its bottom no tools and other extraneous subjects have been forgotten. At battery fastening on the pallet do not tighten clamping bolts of laths too hardly. All metal surfaces of the car damaged by corrosion should be processed and covered by a first coat on a zinc basis, then are painted. The information on removal and battery installation can be found in the Head System of an electric equipment of the engine. The order of carrying out of start of the car from the auxiliary power supply is described in the beginning of the given Management.

Remove covers банок batteries (if those are provided) and stop up apertures with pure rags in avoidance разбрызгивания electrolits. Disconnect a negative wire from the battery from the battery and connect to its plugs of a wire from зарядного devices (with polarity observance - plus - to plus, a minus - to a minus), then include зарядное the device in a network. Track, that the handle of the selector of the device has been established in position 12 Century If you use the power supply with the rated current exceeding (1 - 2) And, whether is regular in a course to gymnastics check the battery has overheated. At gymnastics of the battery from 1 - 2 амперного the power supply, it is enough to track gymnastics course only first two hours then it is possible to leave safely the battery to be charged for the night without supervision. If the battery is equipped by demountable covers банок, the electrolit density should be checked with the help ареометра everyone some hours зарядного a cycle. Ареометры it is possible to get cheaply in any shop of automobile accessories - adhere to the instruction applied on the device. It is possible to consider the battery charged when the electrolit density does not change in two last measurements the interval between which makes 2 hours, and the electrolit in banks starts freely барботировать to (bubble). The difference between indications ареометра in various banks of the battery should be minimum, otherwise () it is necessary to consider the battery/bank faulty. Some batteries of tight type are equipped built in ареометрами and level of their charge is defined on the colour indicator through an observation port. Bright colour usually corresponds to the charged condition whereas indicator dimness specifies in necessity of additional charge of the battery. If the battery of tight type is not equipped built in ареометром, between its plugs for the control over gymnastics course it is possible to connect the digital voltmeter. Pressure of completely charged battery should make not more low 12.6 In the ambassador of removal of a superficial charge. Additional requirements on the battery and carrying out of start of the engine of the car from an auxiliary source can be found in the Head System of an electric equipment of the engine and in the Management beginning (Start of the engine from the auxiliary power supply see).
