Battery technical issues

1. The ideal storage temperature is 15 C and zero humidity.
When this is not possible the phenomenon of self-discharge is enhanced whic is always directly proportional to the increase in temperature and humidity. Avoid immediate sun exposure. Maximum storage life with proper maintenance, 24 Months.

2. Avoid contact of battery with the floor. There must be a minimum distance of 10 cm

3. Do not place more than 4 rows of batteries in height.

4. The maximum slope when the battery is on shelves should be 45 degrees.

5. Charge batteries remaining in the rack so that the voltage is always above 12.60 before it is placed for use. This avoids the danger of electrolyte stratification and thus sulfation.



Calcium batteries are maintenance free because they do not have fluid loss due to negligible boiling during charging.
This,though, creates the following disadvantage:
Due to lack of boiling during charging so that the electrolyte is stirred, when discharged to a large extent and not fully loaded and again, we have the density stratification. The concentrated acid that comes from the plates during charging goes to the bottom of the battery and plates while at the top remains the dilute acid or water. As a result the battery indicates a high voltage while the density and the starting current remains low. This for automatic dynamo is an indication that the battery is fully charged and stops charging. Then you should be charging at 16 volts constant voltage charger and constant current intensity for a while until you boil the electrolyte. A SCHUMACHER charger makes these functions automatically.


In any discharge of the battery sulfuric acid enters the lead plates thereby forming lead sulfate, which if it remains so for some time, crystallizes. In this case the battery is not recharged and is discarded. If we try to recharge it we observe the voltage to rise rapidly. If a battery remains completely uncharged for three days it loses 20% of its capacity, if it so remains for a week it is rendered useless. Sometimes you can save a sulphated battery charging with voltage 16 volts.


It is isnduced by the decline of active material at the bottom. Thus forming a precipitate which connects the plates together conductively. It comes either from overcharging or from a battery hit if not well fixed to the base.

6. Always follow the rule: First in, First out. That means that the first battery entering the store should also be the first to leave.

7. We follow appropriate recharge programs to prevent overloading. We ensure that charging takes place in a well-ventilated area with no flames or sparks near the battery EXPLOSION HAZARD (batteries emit flammable gases).

8. Do not refill elements of open-type batteries with acid or tap water. We use only licensed distilled water.

9. Never short-circuit the poles of a battery with cables or keys to examine if there is current.

10. Always watch the correct polarity when charging and installing.
