Purchasing replacement batteries for your electronic devices can be a confusing process. Should you purchase an original equipment manufacturer or an aftermarket replacement battery for your computer or laptop? There are many benefits to purchasing an aftermarket versus a brand name or OEM notebook battery. You will save money, increase battery life, receive better customer service, and get better warranties. These added benefits are available if you follow our guidelines to purchasing aftermarket netbook and notebook batteries.There are many places to shop for aftermarket laptop batteries, and doing proper research is necessary. Look for long-time, well-established companies if you are shopping online. This can help you put a face behind the company. It is hard to differentiate or gain trust shopping for identical items, where the sole difference is just the manufacturer’s brand name.When looking for a non-OEM battery manufacturer or retailer you want to look at the store’s track record and see how they perform compared to other companies. You can look at online reviews for the company, check to see if they are a member of the BBB, call the company, and if your just not sure ask the OEM manufacturer for their “expert” opinion. All these can ensure that you are buying from a reputable company and will not be a victim to internet fraud or inferior laptop/ computer batteries.You do not want to purchase an inferior battery that cannot withstand the same power charge. You always want to check to see that the battery manufacturer advertises the replacement batteries voltage and mAh capacity. mAh stands for Milliamp Hours-typically the higher the number the longer the battery will last. You will also want to look at the extra features provided, such as surge protection technology, thermal-cut-off, and short-circuit protection. These added features can improve your batteries performance, while ensuring it runs effectively and properly.Some older batteries have a “memory effect,” meaning that once you charge the battery wherever it was last at will be its new maximum output range. Replacement batteries can either have a memory effect or no memory effect. Batteries that do not have a memory effect typically advertise that fact; if it is not mentioned than it’s probably better to stay away from these sellers. No memory effect batteries can be charged anytime without the risk of lowering your laptop battery’s lifespan. Most newer batteries already utilize this technology and as such this is becoming less of a concern.Overall, when the proper research is done you can save a lot of money on computer and laptop batteries by purchasing from non-OEM manufacturers. These aftermarket batteries are excellent for those on a budget; yet require the same performance originally sought out in their computer battery. Even for other electronics, aftermarket batteries are an excellent substitute to OEM batteries. You can purchase aftermarket batteries for cameras, camcorders, GPS, radar detectors, two-way radios, cell phones, and much more.
