Storage

USE SAFETY PRECAUTIONS

Ca-Ca maintenance free flooded charged batteries and hybrid batteries can be stored for 6 and 3 months respectively. Batteries will be damaged if stored in discharged state. All batteries should be stored in a cool and dry location; for flooded batteries, separators (e.g. styropor) must be used if they are to be stacked. Battery surfaces should be clean.

First In-First Out principle should be adopted. Production and storage dates should be included on stacks.  For example, code number 280421 on a battery means that it was manufactured in the production line 2 on 21 April 2008.

Recharge requirement for calcium Ca-Ca flooded batteries:


• Once in every 6 months if average storage temperature is below 27 degrees (*)
• Once in every 3 months if average storage temperature is above 27 degrees (*)
• The battery needs to be recharged when its open circuit voltage drops to 12,4 volts. This method is alternative to methods 1 and 2.
• These periods are approximately ½ for hybrid flooded charged batteries.

ATTENTION: Do not allow acid spillage and temperature to exceed 52 degrees during recharging. If the temperature increases, lower the charge current and stop charging until the battery cools down. High charging temperature damages the battery.

TEST PROCEDURES

USE SAFETY PRECAUTIONS

Always check the following conditions when inspecting a battery:

• Loose, displaced or torn terminals
• Cracked-broken case or cover
• Displaced, broken or obstructed plug holes, clogged gas output holes
• If the battery is not damaged, proceed to the next step

Measuring Charge Level:

Measure open circuit voltage with a precision voltmeter.

NOTE: Never measure the charge level of a battery that is still in the vehicle or has just been taken out from charging.  These situations provide a false high voltage surface charge. In order to eliminate surface charge, discharge the battery by using 15x15A or keeping the headlights on for 15 minutes if it is in a vehicle.

If the charging status:

If the battery is charged for at least 75% (approximate voltage=12.4 *V), proceed to the load test; if it is below 75%, recharge it according to the specified method before the load test. Voltage and intensity values may vary depending on the battery design.

Load Test:
Battery test under load and evaluating the results depend on the systems of devices used. Load test and results evaluation are carried out as per device instructions.

Inspecting Vehicle’s Electrical Equipment:
Inspect the vehicle’s related electrical equipment when installing a new battery or in case of a faulty battery. Most common error in vehicles is over-charging or under-charging. Apply full throttle with a regular battery and check whether alternator output voltage is between 13,8-14,4 volts for hybrid batteries; 13,8-14,9V range is acceptable for Ca-Ca batteries.  (for 12V vehicle)

NOTE: For vehicles where disconnecting the battery causes a blackout for electronic circuits and coding, prevent shutdown of the system by connecting a second battery or by activating a special device before disconnecting.
