The article come from http://www.batteryoffice.com/batteryblog/2009/08/laptop-battery-use-and-maintenance/
1) How to activate the new batteries
Prior to the opening of the new animal cells, plate surface, there will be a certain degree of oxidation. The longer the storage, oxidation more serious. After adding the electrolyte, there will be rapid warming, the charge will show greater resistance to charging difficulties. Therefore, the opening of the new laptop battery should be done: filling the electrolyte, the static discharge of about 6h until completely saturated with the electrolyte plate, the temperature dropped to below 35 ℃, and then connect the power to charge; charge current is tightly controlled within prescribed limits , such as high temperature during charging, more than 45 ℃, the charge current can be reduced or stopped charging; for 1 ~ 2 times charge and discharge cycles in order to achieve rated capacity.
2) how to conduct the beginning of a new battery charger
The Latitude D830 battery positive and negative power supply respectively, then positive and negative, first with the initial charge current charge to the electrolyte release air bubbles, single-cell voltage to rise to 2.3 ~ 2.4V. Then the current drops to 1 / 2 the beginning of the charging current to continue to charge to the electrolyte release violent bubble, the proportion of electro-hydraulic and voltage remain stable until a continuous 3h. Full charging time is about 45 ~ 65h. Charging process should always measure the electrolyte temperature, if the temperature is too high, can be current half, Latitude D620 battery to stop charging or cooling method, temperature was controlled at 35 ~ 40 ℃. Initial charging is completed, if the proportion of irregularities in the electrolyte, the application of distilled water or electrolyte specific gravity of 1.4 and then adjust the charge 2h, until the proportion of compliance so far. The new battery charge for the first time often do not meet rated capacity, should be charge and discharge cycles. With the rated capacity of 1 / 20 of the current discharge from a single cell voltage down to 1.75V, and then add sufficient charge current. Following a charge and discharge cycles, if the capacity is still below 90% of rated capacity, should make another charge and discharge cycles.
3) How to maintain C1295 battery
a. battery during use, water evaporation and electrolysis of water charging both would reduce the surface, so every 5 to 6 days in summer and winter every 10 ~ 15 days should be checked once a liquid height, and then need to increase distilled water. In addition to leakage caused by lower surface, the are not allowed to add electrolyte, or the proportion of the electrolyte will be higher than 1.300, resulting in shortened battery life. Battery liquid level should be higher than the plate 15mm, easy to spill liquid level is too high, corrosion around the parts, there is likely to positive and negative pile conduction, causing self-discharge; liquid level is too low, easy to expose the upper plate surface, not only HD438 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 of (especially short-distance vehicles). One of the following conditions should be to supplement charge: ① the proportion fell to 1.200 below the electrolyte; ② winter discharge Chao Guo 25%; ③ summer discharge Chao Guo 50%; ④ lights dim; ⑤ weak start. Supplementary charge in two stages. The first stage of the rated capacity of 1 / 10 of the current charge, to a single cell voltage of 2.4V, the electrolyte until the bubble began to release, which normally takes 10 ~ 11h. The second phase will halve the current up to date enough, it generally takes 3 ~ 5h. If the proportion of electrolyte irregularities, should be adjusted, its methods and the beginning of the same charge. c. Winter batteries Y4367 battery , Y4546 battery , Y9943 battery should be noted: ① piling and wire electrical connector to ensure a solid connection, good contact; ② to install insulation in the battery device, so as to avoid the temperature is too low, resistance increases; ③ the proportion of the required adjustment of the electrolyte; ④ in the engine running the engine when you add distilled water to the battery charger in order to avoid uneven mixture of water and electrolytes caused by ice; ⑤ cold start the engine preheating should be carried out, each start-up time of no more than 5s, starting to be repeated intervals 15s, if the three start - unsuccessful, should be carried out checks, do not blindly re-start; ⑥ always keep enough power to charge storage state, to prevent the electrolyte reduced the proportion of the ice, and even damage to batteries.
4) How safe operation when the battery maintenance ThinkPad T40 battery in the warranty, they should observe the following safety requirements: ① moved when the light-light battery can not be skewed in order to avoid electrolyte splashed on clothing or skin, causing corrosion or burns. If they are splash, immediately flush with water. ② Check the electrolyte specific gravity and surface height, so that a little straw to leave the entrance of the electrolyte injection can be, not to mention too high in order to avoid electrolyte spill. ③ to prohibit oil containers and various metal objects on the FRU 08K8193 battery housing. ④ In the preparation of electrolyte should be used when ceramic containers, and sulfuric acid slowly into the water, the absolute prohibition of water poured into the sulfuric acid so as to avoid splashing sulfuric acid burns the skin and clothing, and even the container burst causing the accident.
5) how to make the battery discharge
The new battery to charge and discharge cycles and test batteries ability to work, the basis having regard to discharge a certain standard to test whether the battery rated capacity. ASM 92P1140 battery Rated Capacity 1 / 20 of the current discharge from a single cell battery voltage of each of 1.75V, and 2h at the beginning of each measurement time after discharge voltage, the voltage down to 1.8V voltage drop after the result of faster, should be 15 ~ 20mim a voltage measurement , the voltage down to 1.75V, it should immediately stop discharging, or voltage drop dramatically to the "0" so burn plate, causing difficulties in the next charge. Discharge many ways (such as the use bulbs discharge, with the variable resistor discharge, discharge with the electrolyte and using a lower voltage battery discharge), can be selected according to specific conditions. In the discharge line, you must access ammeter in series, parallel on the voltage meter so that timely observations voltage value, lost no time to stop discharging.
6) how to reduce battery capacity to do
FRU 92P1137 battery charge, use of time is not long enough to save electricity, starter rotation weakness, difficulty starting the engine, speakers, sound volume reduction, lighting is dim, with high rates of discharge of dollars checklist cell battery voltage is lower than 1. 5V, namely, reduce the battery capacity. Generating capacity should first check whether it is suitable voltage regulator is too low, whether due to long-term storage battery self-discharge, whether to use starter too often, is commonly used because of their low electrolyte liquid electrolyte instead of distilled water by adding batteries, if you do not above-mentioned problems, should open the battery cover and check whether the lack of electrolyte. If the liquid level is too low and too long, so that exposed part of the plate curing, they should check out plate. If the surface of plate showing a layer of white lead sulphate, explained that it had vulcanization. If, after taking the plate, pour the electrolyte in the ThinkPad T60 battery there is too much off the bottom shell plate active material or other impurities, indicating that these substances caused by a short circuit between the plates, causing inadequate capacity. 7) How to diagnose battery charge storage capability, decrease fault
Drop charge storage capability, commonly known as "run electricity", the main phenomena are: day before power is still close enough to keep car the next day starter on the weak rotation; engine flameout time for a little longer, then start there are difficulties; lights dim, the loudspeaker does not ring. Should check whether the battery wire Datie. If Datie, available high-rate discharge single-cell voltage meter to check each hour inspections. Such as the start voltage reaches a certain value, it became an instant rapid decline, seriously nowadays down to 0, indicating short-circuit fault between the plates. Open the D5318 battery cover should be used extract the electrolyte tube, such as the electrolyte turbid, indicating the electrolyte impurities. You should remove the plate, out of partition observation, such as a perforated partition, indicating the failure was caused by perforated partitions. In addition, the surface should also check the battery electrolyte is dirty, and whether there is overflow.
How to prevent battery explosion
In the beginning of a new battery charging, discharging process, water is broken down to produce a large number of hydrogen and oxygen, if not promptly released, it will face sparkle 1K500 battery explosion. ① should always check and clear the battery cover of the vent stuffed to ensure that internally generated emissions of the gases out of time; ② the internal battery connections and electrical connections on the pile should be firm, in order to avoid electric discharge; ③ try to avoid piling on the battery power scratch fire, so as not to detonate; ④ first opens the battery segue, and then check the high rate of discharge of dollars.
9) How to use batteries instead of battery
The car is not damaged when the battery or batteries can be used instead of 6 to 8 dry batteries 8N544 battery , 9H348 battery. Methods were: dry batteries together, using cardboard Juan Chengyi body, one end of the Da Tie the other end to pick with a wire coil on the ignition switch terminal, and then quickly shake his hand crank the handle, you can start the engine. When the engine reaches a certain speed, confident that when the generator can supply, and then removed.
