1, level of battery fluid inspection and other
Battery fluid level should be the upper and lower limits, between 10 million can not be below the lower limit, below the threshold should be added soon. Added should not be re-injected in the diluted sulfuric acid, or batteries will be damaged due to the high concentration of electrolytes. Even less filling tap water, river water and so on.latitude d420 battery , Because it contains calcium, magnesium and other ions and impurities. Pricing, the role of these substances by radiation damage adsorbed on the surface of the battery plates. Therefore, we must add water, distilled water, or market, charging the battery popular light (after the effective use of good results). Battery fluid level should be regularly monitored, the general added that a monthly check once a summer, high temperatures, it is recommended to add a half months examination. It should be noted is that for the maintenance free sealed battery and do not need to add liquid, and do not open the closures.
Then check the battery state of charge of pre –
Check the battery voltage is below the standard value, conditional can detect what proportion of the electrolyte is less than 1.28 (20 ℃). To observe the internal battery, if one or more corrosion cells, white trim, or at the bottom of the material accumulation, or deformation of the plates, then the battery must be replaced. If the battery terminal, they are dirty and have been corrosion or oxidation, may be a cleaning brush wire. If cleaning is dirty, corrosive electrolyte can run a little dry surface with water.
3, charging battery
This is a battery maintenance of the most important part, which directly affects battery life. Charging, the current can not be too great, it is recommended not to use the fast charge. Loading, please use the charge current rating of half the size of the current will double the rated load of time. sony vgp-bpl11 , Charging, the batteries in cold water cooling (water or battery 4 / 5). Because the load when the battery in a lot of heat, if not try to heat could lead to plate bending, causing damage to the batteries. Charge Non-Plug sealed battery must be open and airy, away from fire in place to prevent the hydrogen gas generated by the perception of the explosion.
Fourth, after the detection of battery charge
Charging the battery, do not rush to test, should set aside time for 30 minutes after the inspection. Otherwise, it does not accurately reflect the condition of the battery. First, check and correct fluid level, and then use a multimeter (preferably digital multimeter) by measuring its voltage. 12 volts (6 volts) and the battery must be equal to or greater than 12.8 volts (6.4 volts). If less than 12.7 volts (6.3 volts) will also be necessary to continue to charge. If 12 volts (6 volts) The following, then the battery has been damaged and must be replaced. It should be noted that the mode of ignition should not be used to determine the size of short-circuit current can be used with battery with a rated voltage of the headlight bulb with the battery connected, lit for 5 minutes time to observe the lights as the lights dimmed or extinguished obvious, note the battery is damaged and must be replaced. tecra a3 battery
In addition, the choice of charger is also very important. Charger, variable voltage (current) type, type a constant pressure, the type of constant current, etc., it is preferable not to use the home charger. Pairs of maintenance free sealed battery is preferable to use a special charger. It should be noted, some type of constant pressure, the constant current charger can not provide maintenance-free sealed battery charge.
If we insist on using the method above to perform maintenance on the battery, the battery life may be extended to 2056 a1281
