Teach You Some Tips to How to Choose the Right Battery
Key Indicators of the battery of course,is the battery life.On the surface,this is just a simple specification,but it is related to many factors,including: system load (full load current supply,a part of the circuit or microamp time power supply),energy efficiency,power management system,battery types and charging methods.In addition to the special importance of the interaction between these characteristics will improve or decrease the feelings of the end user.Under normal circumstances,when users began to notice the existence of the lithium battery,things get more difficult!
Alkaline batteries so that the point of non-rechargeable battery,but they have very low self-discharge rate and the cost.For low power applications,the alkaline battery is a good choice,subject to reasonable use of current of rest or sleep current must be very low.A common misconception of the design:only for work efficiency,while ignoring the “sleep””off” or the state of the power loss,or even hundreds of au of current can lead to a replacement common to the battery consumption of the battery.Now,using the design of many soft switches to replace the mechanical switch (mechanical switch can completely disconnect the battery connection).However,this misunderstanding of the design compared to some years ago,but is more common.
Good product design does not require a replacement battery,hp pavilion dv4 battery do not require frequent replace battery,so that the battery of the user’s eyes “disappear”to.Avoid user concerned about the capabilities of the device also concerned about the battery.The mutual restraint between the battery and the system is often overlooked problem in the design to ensure that the capacity of the battery and the consistent system requirements is essential.Type commonly used battery: alkaline batteries,nimh batteries and lithium-ion Compaq Presario r4000 battery.They are not interchangeable,the vast majority of products have a better option.
Another adapted to the application of the NiMH battery is an alternative to alkaline batteries,batteries are exhausted the battery of the device by an external charger to charge the battery.This application is more frequent in digital cameras,but requires frequent user.Many portable products ibm thinkpad r40 is different from the situation above,PDA,cell phone on the need for smooth loading,but they are rarely the consumption of electricity consumption.These products are the best choice of the lithium-ion density in addition to weight,the battery also has two important advantages: low self-discharge rate for a short period of charge-discharge is no limit.Consumers do not consider the problem of battery management,and simplify the use of the product.
When the load of alkaline batteries in terms of is too large,the need for the selection of the rechargeable batteries,laptop products,PDA,cell phone and continued on become the standard mode.The rechargeable battery as little as possible to disrupt the user,have a role in the promotion of the product,at least not reduce the performance of the product.There are two choices of rechargeable batteries:nickel-metal hydride or lithium batteries.Cost of NiMH batteries,lithium-ion battery is low,when the official use of the product in terms of insecurity on the battery,this choice will become very sensitive.The issue of the absence of complexes of load low-cost products is more important,because NiMH batteries suitable for battery fully charged and fully discharged.This is more appropriate for products which,often the energy is completely exhausted, such as: power tools.
