  Q: What precautions should be taken when handling batteries on Volkswagen Golf?

  A:

  Make sure that you never leave the cable on the negative battery terminal unless first and to the tool you are using to loosen the cable clamps until it is last or the battery will be shorted. In case the audio system has the anti-theft system, then make sure that you have the right activation code before detaching the battery. The vehicle may have some systems that need to have battery power at all times either to keep operating (alarm system, power door locks, etc.) or to retain control unit memory (radio station presets, Powertrain Control Module and other control units). In case of battery change, the power keeping these systems is switched off and it is necessary to learn the systems again before the systems will operate correctly. Consequently, prior to disconnection of the battery, it is prudent to ensure that on a powered door lock vehicle, one should take out a key in the ignition key and hold on to it, lest it gets locked inside the vehicle when the power door locks come into play accidentally when the battery is reconnected. Some of these issues can be prevented with the help of devices referred to as memory-savers, which can be generally plugged into the cigarette lighter and connected to a spare battery, which is generally enough to provide current to keep audio unit security codes, PCM memory, and even power to always hot circuits like the clock and radio memory circuit. To un-hook the battery to facilitate service operations where power should be disconnected to the vehicle, one has to shut the ignition and take off the key, then remove the battery cover or negative battery terminal cover, loosen the cable end bolt and detach the cable end of the negative battery terminal and isolate the cable end to avoid any accidental contact with the battery terminal. To restart the battery, reconnect the negative battery terminal, insert the key in the ignition switch and switch it to the On position, and then the Off position, and connect a scan tool to detect any trouble codes, turn on the ignition and reset the clock, fully open and close all the windows and the sunroof to reset the auto stop features, and then, when all the windows are closed completely, continue to hold the switch in the closed position till a relay click is heard. Turn on the car; the steering electro-mechanical steering alert (ASR/ESP) light must now be activated. Steer the car straight ahead at a maximum speed of 10 to 13 mph over a short distance in order to re-calibrate the steering angle sensor and switch off the warning light.

  Q: What precautions should be taken regarding batteries when disconnecting and maintaining their functionality on Volkswagen Jetta?

  A:

  Disconnection of the battery should be done only with great care since it might require re-learning on how to use the system properly and also should the audio system contain an anti-theft mechanism, the right activation code must be known beforehand. The battery has a regular preventative maintenance program that will guarantee consistent starts and safety of handling requires the right equipment. Safety measures involve switching off the engine and other accessories and disconnection of the negative terminal first. The battery produces flammable hydrogen gas, and thus, do not use sparks, smoke, or fires, and never charge where there is not good ventilation. Electrolyte is poisonous and corrosive; protective equipment is needed, and children should be avoided. Check the battery, look at any damage and corrosion and lose connections and in case of corrosion, take out the battery and clean it, beginning with the ground cable. Wipe down clean and clamp with a baking soda solution and do not allow any solution to get into the battery and also wear protective clothes when doing so. Make sure that battery tray is in place and hold-down clamps are in place but not strained. More resources can be used in jump-starting and detailed battery examinations. It is possible to clean corrosion using a solution of baking soda, and use a zinc-based primer on any damaged metal. During the charging process, watch out of the hydrogen gas production and no flames, with the use of eye protection. Discharged batteries should be charged at slow rate, especially during wintertime, when discharging a battery, a one or two-amp charger is the best to use, whereas higher amperage chargers must be used with care. The instructions on the charger will normally give the charging times that the charger will require and trickle chargers will require a 12-16 hours to fully charge a battery.
