1, the preparatory work
AR with pure water and a solution of sulfuric acid, electrolyte configuration, proportion, 500ml water, add 0.5 ml of pure sulfuric acid.
Prepare a standard rubber valve in the exhaust.
Tools: screwdriver, straw (which can be used instead of disposable needles), clear diameter polyethylene pipe should be suitable for straw (needles) inlet. ABS plastic.
2 along the top of the vent forced the battery. Some of the Laptop battery cover is a glue ABS, a number of cells is connected by a loop. Note that forced open the lid when not to damage the lid. So you can see 6 Cape exhaust valve rubber.
3 Open the rubber cap, exposed escape through the chimney can be seen inside the battery. Some battery rotary exhaust valve is open, as the days may be the battery is the case. Some cells there is elastic around the filler cap and pay attention to ensure the stuffing.
4, with good drops inhalation prepared by a row of holes in the electrolyte electrolyte. Electrolyte to cover only the plate of 1mm.
5, the electrolyte filling the battery cover with breathable material proper ventilation category covered to prevent dust from falling into the wind, still 24 hours to observe the interior of the vent electrolyte there should be flow of electrolyte, or if you want to add electrolytic fluid.
6, the wind does not qualify for the smallest to the nominal 12V to 16.2V Dell Latitude D505 battery voltage constant current limit. The battery is best placed in acid-resistant containers to prevent spillage of the electrolyte environment. The load current of the battery has dropped to 400mA ~ 300mA or voltage 16.2V 3 hours after the initial charge that the battery is full.
7, after the end of the initial charge, check the surface of the electrolyte of the battery, if, without electrolyte, the electrolyte should be added later, again limiting constant tension, if there are six cells inside the electrolyte with straw to suck the excess electrolyte.
8, using current limiting constant voltage 14.8V until the charge current dropped to 300mA.
9, Re Cover install exhaust valve exhaust valve later, attention to resume stuffing. If the exhaust valve is opened in rubber, it is better to replace them, if the characteristics of a good may or may not change, but be sure to check the flexibility, if flexibility is not good, we must find a good exhaust valve replacement.
10, cover the hp F3172A battery cover, if the bonding time and bonding should. Yet another 24 hours until completely solidified gel, which further limits 14.8V constant voltage until the charging current dropped to 300mA.
11, once again test the capacity of the battery, the battery capacity to determine whether to reinstate him.
Maintaining good battery (capacity increased by less, or who do not meet the nameplate capacity of more than 70%) reasons:
1, positive plate battery to soften its remarkable performance: In the 7 steps above, you will find suck the electrolyte impurities than black, if the impurities are more black then, softening is discharged positive plate, so that the battery base can not fix can not be discarded.
2, vulcanization, the battery, the restoration project of the batteries after the pulse, once again the burden.
3 load after 30 minutes, test the battery voltage, but lower than 12V, the circuit may be internal battery. The battery must be discarded.
Chargers – leaf green, essential
The quality is good or bad life toshiba PA3285U-1BRS battery charger is directly related to the length, and even some low quality charger will also lead to battery charging and deformation. So generally, the production of ordinary battery charger and battery manufacturers are supporting production. However, there is the quality of the magazine market is uneven, some manufacturers for the pursuit of profit and ignore the batteries and matching chargers, and consumers are also less costly for the love of a moment, the choice of charger is not enough scientific and rational. Therefore, the choice of shippers, we must pay attention to the choice of regular charger manufacturers, and manufacturers to do with the manufacturer of the battery charger online, so even if the failure, but also be able to find the appropriate vendor repairs or returned.
Motor controller – the backbone of electric cars to travel
According to some insiders, is the electric vehicle start-up engine and acceleration features such as the completion of the key, and the level of engine performance will lead directly to the life of batteries. The Promise controller that the speed of the vehicle electric power braking, soft start functions such as using “body” if the limit is unreasonable design is too large, may seriously affect the battery life engine. Thus, the purchase of electric vehicles, they need to go over a test drive, multi-feeling. Take a look at electric cars start, acceleration, fixed speed, braking, balance and other functions is consistent with the instructions.
