Maintenance And Care - Helvi DISCOVERY 120 Manuel D'instructions

C. Improper connection of Charger and battery polarity
D: Charging stopped under "Desulphation" or " Absorption" mode, then press "MODE"
button could resume to charging, if still have the same problem, maybe caused by:
• 1. Battery is over-sulfated
• 2. Battery can't be charged
• 3. Battery can't hold the charge
Under these conditions, the battery charger will stop charging. In the event of A B or
D the battery may be defective and we advise you to consult your nearest battery
service centre. If the problem is attributable to C, please ensure proper polarity then
start to charge
It is essential to keep your battery regularly charged throughout the year, especially
during the winter months. In the winter the effectiveness of your car battery is redu-
ced by the cold. Oil is thick. Engines are difficult to start and the heater, windscreen
wipers and lights are all draining power. It is at this time that batteries have to be at
peak power. If your battery is not regularly maintained and kept fully charged, it can
cause problems and a possible breakdown.
Listed are some helpful hints on how to keep your battery healthy in conjunction with
your Battery Charger.
Faulty Cells
Batteries are usually made with six cells. One of these cells can deteriorate or get dama-
ged. If, after several hours charging your battery is still flat, you should test the battery.
ONLY for NOT sealed batteries:
Take hydrometer readings from each cell in the battery. If one reading is lower than
the others, this could indicate a faulty cell. If necessary, get an Auto-Electrician to
check your battery. One faulty cell is enough to ruin your battery.
It is pointless to continue using it and you would be better getting a new one.
Care
Sometimes the battery may appear flat, but this could simply be dirty or loose con-
nections on your battery terminals. It is important to maintain the leads on a regular
basis. Do this by removing the leads from the battery, clean the inside of each con-
nector and terminal posts on the battery, smear the terminal posts and connectors
with Vaseline, refit in there correct positions and tighten firmly.
It is essential to keep the electrolyte level above the plates.
Note, however, that you should not overfill it, as the electrolyte is strongly acidic.
When topping up do not use tap water. Always use distilled or de-ionized water. It
is important to keep the acid level up. If necessary have it checked by your garage.
Checking the condition of your battery (ONLY for NOT sealed batteries)
Using a hydrometer, which can be purchased, from most motor accessory stores,
you can check the specific gravity of the electrolyte in each cell. The hydrometer is
use to suck up a quantity of fluid from the cell. The weighted float inside the hydro-
meter will register the condition of that cell. Put the fluid back into the cell after te-
sting, taking care not to splash the fluid about.
