In winter, the proportion of the battery falls hardest test. Only one cold start which is as silenok something is not enough - how to recharge during the short winter "runs" the battery does not have time.
Therefore, the battery should be helped - it was from him, not least depends whether you travel by road in relative comfort, or dancing in the cold, looking for "brother" who would "light a cigarette."
If you're not going to put the car on the joke, then the battery need to do right now. Do not be misleading confident battery life in the summer.
Unfortunately, many drivers look back on the battery only in the first, severe cold, when the final torment battery failed attempts to start the engine - the discharge duration (more than 20 seconds), large currents lead to the dislodging of the plates.
First of all, clean the dirt enclosure, cover and vents the battery, then wipe the surface with a weak battery (10%) solution of ammonia. Plaque from the terminal and the Terminal is removed with warm water, the oxide film - fine-grained sandpaper. (When installing the battery into place do not forget to tighten bolts and lubricate the outside terminals and conclusions "litho.")
Minor chips and small cracks the plastic liner or cover you can eliminate yourself with a soldering iron. Serious injuries require the participation of specialists.
Next step - determining the level of battery charge and condition of the individual cans. We can not do without instruments - at least, need to load the plug. Therefore, further manipulation of the battery should be entrusted to professionals.
In a specialized company that you check the electrical parameters of the battery, will bring them back to normal (unless, of course, the battery is suitable for further use), and simultaneously examined electric car. Do not skimp on this procedure. Defective relay will spoil the most expensive battery for a few days.
Now you have the battery is fully ready for the winter. Help it to maintain "good shape".
Winter crank the engine makes use of motor oils with low viscosity. The faster the motor will work, the less load on the battery.
The cold electrochemical processes in the accumulator is slowing, and battery capacity is much smaller than the nominal. Before responsible travel put the battery for several hours in the heat.
At a parking lot or in an unheated garage is not superfluous to wrap up the battery on the night - an electrolyte cools more slowly in ambient air. Before starting the engine blinked distant light - the battery should "wake up".
Charge the battery, even a low maintenance, winter should be on a monthly basis. Electrolyte density monitor weekly. Norma - 1,27-1,28 g / cc. See Distilled water, if necessary, top up just before the start of movement, otherwise it will freeze.
By the way, the density of the electrolyte. Some automotive publication in the winter are advised to raise it to 1.30 g / cc. Indeed, the Bank will work in the cold, more confident. However, battery life is shortened.
And now a recommendation, which many motorists deem unworthy. We do not advise you to use your battery as a "lighter" to another machine. At the time of "lighting a" battery is experiencing extreme stress, clearly not reaching her favor.
To prepare the battery for the winter should those who are not going to operate the vehicle in the most severe season.
A fully charged battery is stored in the cold - with temperatures below zero self-discharge is reduced. However, in severe frosts nedozaryazhennaya Bank may suffer. Electrolyte density 1.22 g / cc. cm (about 60% charge from the norm) freezes at-38oS.
To store the battery for over half of it is poured and filled with an electrolyte passivating solution of boric acid.
