FAQ

Can I leave the battery unused for a long period of time?

Yes you can, but you must check its charge status every now and then (about once a month) and perform a charging cycle if necessary. Never leave the battery flat as it may become difficult to change due to the plates sulphating.
 

How long does a battery charging phase last?

This basically varies according to:
- Residue charge level
- Charging method (current charging curve)
- Temperature

When should I water my batteries?

Water is lost during charging. Therefore, the best time to water your batteries is always at the end of the charge cycle. However, if the electrolyte level is extremely low or the plates are exposed to air, add some water to cover the plates before starting the charge cycle.

Do you ever add acid to a battery?

Under normal operating conditions, you never need to add acid. Only distilled, deionized or approved water should be added to achieve the recommended levels mentioned above. When a battery is shipped in a dry state or accidental spillage occurs, electrolyte should be added to the battery. Once filled, a battery should only need periodic water addition.
  

How is a battery fully charged?

There’re two ways to charge a storage battery:

The first way:

  • Open all buttons of the storage battery.
  • Use a DC source with a current equivalent to 1/10 of the storage battery capacity to charge. For example, the storage battery of 50Ah capacity should be charged by the 5A DC power source.
  • Connect the positive wire (+) of the source with the front positive terminal (+) of the storage battery, and connect the negative wire (-) of the storage battery with the rear negative terminal (-) of the storage battery.
  • When the electrolyte solution of the storage battery cells boils, lower the DC source to a half and continue its charging.
  • The charging finishes after 2-hour constant charging voltage.

         The second way: 

  • Open all buttons of the storage battery
  • Use a DC source with a current equivalent to 1/10 of the storage battery capacity to charge. For example, the storage battery of 50Ah capacity should be charged by the 5A DC source.
  • Connect the positive wire (+) of the source with the front positive terminal (+) of the storage battery, and connect the negative wire (-) of the storage battery with the rear negative terminal (-) of the storage battery.
  • When the charging voltage reaches 14.4V, continue its charging for more 5 hours.

Why is the storage battery difficult to be started?

Possible causes

Solution

·        The storage battery is not appropriately charged

·        Recharge as instructed

·        The storage battery's capacity decreases because of long usage

·        The storage battery has low capacity

·        The storage battery has an internal error

·        Replace the storage battery

 

Why is the terminal of the storage battery sparked and burnt?

Because the terminal is not connected tightly or due to an inappropriate terminal (type, size,...), as a result the terminal can be easily burnt when being started. Therefore, the selected terminals should be ensured the appropriateness, mechanic and electric strength, and aesthetics.

Why is the storage battery exploded?

Possible causes

Solutions

  • There is a spark after charging the storage battery:

               + Static electrization

               + Short circuit in the car

Check the joints in the electric system

The storage battery has an  error in the cell: bad connectors upper the electrolyte solution, as a result there is a spark when the storage battery starts.

Replace the storage battery

 

Why is the storage battery hot and in loss of much water?

Due to overcharging, overvoltage and the recharger should be checked.

Why does the storage battery have a short life?  

Possible causes

Solutions

Used for wrong purposes: the storage battery which is designed for starting is used for lighting, the storage battery is fully discharged.

It is recommended to use the storage battery which is designed for lighting.

The storage battery has been stored for a long time after being fully discharged.

The storage battery should be fully charged before long-term storage and every month during storage time ,the storage battery should be periodically recharged to avoid sulfatization.

 

Why does the storage battery run out of electricity?

Possible causes

Solutions

  • The storage battery is not appropriately charged
  • Recharge as instructed
  • Check the charger
  • The storage battery is contacted in the cell
  • The storage battery is sulfated
  • Replace the storage battery

 

Why is a or more storage battery cells boiled when there is a high load current (when starting or trying starting)?

The storage battery has some  failed cells: The terminal plates in the cell are not properly contacted with the lead shoulder or the lead shoulder is cracked or the joining bridge is badly connected.

In this case, the storage battery should be replaced by a new one.

How to identify the overcharged storage battery? 

Commonly, when looking into the cell, we will see the swollen side of the positive plate and the electrolyte solution is red brown when being swung. That’s when the storage battery is heavily overcharged. 

In case that the storage battery is not heavily overcharged, the worn side of the positive will be detected only when the storage battery cover is cut.
