Rechargeable battery using tips

1) How to enable a new battery

Before the opening of the new battery, the plate surface will has a certain extent of oxidation. the longer the storage time, the more severe oxidation. Added electrolyte, the rapid warming occurs, the charge will have a greater resistance, so that charging difficulties. Therefore, the opening of the new battery should be done: After filling the electrolyte, static discharge around 6h, to be completely saturated with the electrolyte plate, the temperature dropped to below 35 ℃, and then connect the power to charge; Strictly control the charge current within the specified scope, if the temperature is too high during charging , more than 45 ℃, should reduce charge current or stop charging; for 1 to 2 times charge and discharge cycle in order to achieve the rated capacity.


2) How to charge a new rechargeable battery

The battery such as Hp F4098A battery,
Hp F4809A battery, Compaq Presario NX9010 battery,
Compaq Presario NX9000 battery, Compaq Presario R3000 battery, Hp Pavilion dv2000 battery, Hp pavilion dv6000 battery, Hp Pavilion ZT3000 battery, Hp CGR-B1870AE battery and Hp HSTNN-LB31 battery positive and negative were connected positive and negative of power supply, First charge with the initial charging current to the electrolyte release air bubbles, single-cell voltage to rise to 2.3 ~ 2.4V. Then the current drops to 1 / 2 initial charging current, to charge to the electrolyte release violent bubble, electro-hydraulic stability of gravity and constant voltage until the row 3h. Full charging time is about 45 ~ 65h. Charging process should always measure the universal laptop adapter electrolyte temperature, if temperature is too high, can use the half current, stop the charging or cooling method, temperature control in the 35 ~ 40 ℃. Initial charging is completed, if the proportion of electrolyte irregularities, application of distilled water or electrolyte specific gravity of 1.4 after adjustment charge 2h, until the proportion of the required date. After charging the new battery for the first time often have reduced capacity, should be charge and discharge cycle. With a rated capacity of 1 / 20 of the current discharge to a single cell voltage down to 1.75V, and then add sufficient charge current. After the first charge and discharge cycle, if the capacity is still below 90% of rated capacity, should be a further charge and discharge cycles.


3) How to maintain the battery


a. batteries during use, evaporation and electrolysis of water are charging will reduce the surface, so every 5 to 6 days in summer and winter every 10 to 15 days should be checked fluid levels, as required, plus distilled water. In addition to reducing surface caused by leakage, the electrolyte does not allow to add, or electrolyte specific gravity will be higher than 1.300, thus shortening battery life. Battery electrode surface should be higher than 15mm, too easy to spill surface, corrosion around the parts, there is likely to positive and negative pile turn, lead to self-discharge; liquid level is too low, easy to expose the upper surface plate, not only battery capacity will decrease, and the exposed plate will soon be curing.


b. in the use of batteries due to different working conditions, often charging less than the phenomenon (especially short-haul vehicles). One of the following conditions should be added charge:

① the proportion fell to 1.200 the following electrolyte;

② winter discharge over 25%;

③ summer discharge over 50%;

④ lights dim;

⑤ weak start. Additional charge in two phases. The first stage of the rated capacity of 1 / 10 of the current charge, to the single cell voltage of 2.4V, the electrolyte bubble began to let up, which normally takes 10 ~ 11h. The second phase will be sufficient up until the current half, it generally takes 3 ~ 5h. If the proportion of electrolyte irregularities, should be adjusted, its methods and the same initial charge.


c. Winter battery should be noted:

① piling and wire electrical connector to ensure a solid connection, good contact;

② to install insulation installed in the hp pavilion dv6000 battery so that the temperature is too low, the resistance increases;

③ the proportion of the required adjustment of the electrolyte;

④ in the engine running the engine to the battery charging plus distilled water to avoid uneven mixture of water and electrolytes caused by ice;

⑤ cold start when the engine preheating, each starting time of not more than 5s, start to be repeated intervals 15s, if the three starting unsuccessful, should be checked, do not blindly re-start;

⑥ often to keep the fully charged state of charge storage in case the electrolyte reduced the proportion of the ice, and even damage the battery.
