Laptops all have a battery. When a power outage occurs, the laptop needs to use this battery to continue to operate. At the same time, the standby time of the laptop greatly depends on the performance of the battery, so How to choose laptop battery? How much do laptop batteries cost? Below we will give you the answers one by one for your reference when purchasing.
How much does a laptop battery cost?
There are many laptop battery manufacturers on the market now. Some laptop batteries purchased online are relatively cheap, with prices ranging from 200 to 500 yuan; and we buy them in specialty stores. The price of purchased laptop battery is about 500-1000 yuan.
How to choose a laptop battery?
1. When purchasing laptop batteries, in addition to the type of battery, we should also pay attention to the battery capacity and actual usage time. Generally speaking, the battery life is best to exceed 3 hours to meet the needs of daily mobile office. At present, the battery capacity of laptop computers is generally 3000 to 4500mAh, and there are very few equipped with 6000mAh capacity. The higher the number, the longer it will last under the same configuration.
2. The quality of laptop batteries must attract consumers' attention, because all major laptop manufacturers have encountered trouble due to poor battery quality. For example, Dell's DELL laptop battery short-circuited and caused a fire. Due to the accident, all 27,000 laptop batteries had to be recycled; COMPAQ also recycled and replaced approximately 55,000 battery components sold with some laptops for reasons similar to the Dell incident.
3. Since laptop batteries are highly profitable, unscrupulous merchants often sell assembled batteries or second-hand batteries as original batteries on the market. The mold used to assemble the battery casing does not have the original battery specifications, so it may be difficult to install or loose when installing it into a laptop; the production nameplate of the assembled battery is not as good as the printing quality of the original battery, and the writing is rough and unclear. When purchasing, If you encounter such an "original battery", don't buy it. The difference between second-hand batteries and new batteries is that the electrodes have more wear marks, so the gloss is not as good as new batteries. Moreover, the shell of second-hand batteries may have scratches or color changes after being in contact with the outside world for a long time. When purchasing, Don't buy this so-called "new battery". Since the monitoring and protection circuits in the original battery are well done and the cell quality is relatively good, the weight is much larger than that of the assembled battery that has cut corners. When you weigh it with your hands when purchasing, if it is much lighter than the original battery of a laptop, Don't buy such a battery either.
4. When we buy a laptop, we must pay close attention to what kind of warranty the manufacturer provides for the battery. The battery has the shortest warranty period among all laptop accessories. Most of them only have a warranty of 3 months to half a year, and some are even not covered by the warranty at all. There are very few batteries with a warranty of up to one year. Therefore, consumers must ask clearly about the battery warranty time and conditions before purchasing a laptop computer. After all, laptop batteries are expensive.
