Remarks on security measures:
Before a charge of the storage battery familiarize with remarks on the security measures given in the Section Check of a condition, adjustment and replacement of brushes of screen wipers:
· Do not disconnect the storage battery at the working engine.
· Never close the battery накоротко, i.e. do not connect positive (+) and negative poles (-). Thus the battery is warmed up and can burst.
· Do not use near the battery an open flame. The electrolit is poisonous. Do not allow its hit in eyes, on skin and on clothes. Otherwise plentifully wash out electrolit water.
· At the battery with central gazootvody, at a charge, a stopper (crosswise shlitsa) do not turn out.
· Before a charging of the frozen battery let's to it be defrozen. The charged battery freezes at temperature near 65°С, the semi-charged battery at temperature near 30°С and discharged at temperature near 12°С. After defrosting the battery check on existence of cracks. If necessary replace.
· At a battery charge the normal charger or the device with the accelerated charging remove the battery. At least, disconnect the negative (-) and a positive cable (+).
· At use of the portable charger (a small current) the charging can be carried out without battery removal. A cable to an onboard network to disconnect thus it is not required. It is necessary, naturally to consider data of the manufacturer of the battery.
Charging of strongly discharged and sulfatirovanny storage battery
The storage battery, long time not used (for example, at long parking of the car), is discharged and сульфатируется over time.
If tension of idling of the battery lies below 11.6 In, the battery is considered strongly discharged. Check tension of rest, thus address to subsection “Check of the storage battery”.
At strongly discharged battery of electrolits consists almost of one water.
Strongly discharged battery сульфатируется, i.e. on a surface of electrodes large low-soluble crystals of sulphurous lead are formed. The electrolit thus loses transparency and gets weak white coloring.
If strongly discharged battery is charged directly after the category, the sulfatatsiya occurs again. Otherwise plates of the battery continue to harden, and possibility of a charge of the battery for a long time remains limited.
Strongly discharged and sulfatirovanny battery should be charged by the lowered current about 5 %, i.e. at, for example, capacity of the battery 60 of Ach force of a charging current should make 3 And.
Tension of a charge should make no more than 14.4 Century.
The fast charging/the help at start
The device for a fast charge charge the battery only for ensuring start of the car. Thus force of a charging current makes 20 % and more from battery capacity. Thus the battery is damaged, since is exposed to influence of big currents. Time not used and strongly discharged battery is long it is not necessary to charge the device for a fast charge since it leads to a sulfatatsiya.
