In our life we always ask How many Cycles of Charge can a Standard Laptop Battery go through? and now i will give you my answer for reference. http://www.udtek.com/hp-pavilion-dv8000-ac-adapter-90w-185v-49a-p-294 6.html Regular lithium ion batteries that power laptops can be recharged 300-500 times before you notice a drop in charge retention.Reconditioning can help you extend the laptop’s battery(hp dv8000 battery ) life as long as the battery itself is not completely dead. It needs to hold at least 45-60min of charge to be considered suitable to recondition. Like car batteries, laptop batteries can be recharged up to 500 cycles. Once the cycle of 300-500 charges is done (in about 2-3 years), you will notice your a steady decline in your battery’s charge retaining capacity.If you don’t want to junk it yet, reconditioning is the answer to revive and reuse an old laptop battery such as my hp pavilion dv6000 battery. So how do you figure out if your own battery can be reconditioned? Simple! Just see how long it runs on a full charge when you put on you laptop ac adapter. If the time till complete discharge is about 1 hour, the battery can be reconditioned.But if you notice the battery discharging in just a few minutes, then it needs to be replaced.
