Here to summarize the U.S., with original equipment hp laptop battery and fake batteries have important distinction separately the following:
1. Battery metal contacts of different color, the metal contacts with original equipment presario 2100 battery deep partial color, fake batteries partial shallow metal contact.
2. The metal contacts with original equipment batteries and not reflective. Lighting at this point that the fake presario 2500 battery are a high degree of reflection.
3. Original hp f2299a contact metal grillwork no obvious side, and side Check the size of relatively small, fake battery contacts with a metal grillwork obvious side, and side Check the size of relatively large, in the light obviously can be observed out.
Fake hp f3172a is to identify the basic elements of the above, and in this I would like to remind everyone, buy the battery, then claimed that if the merchants are original equipment batteries, but the price, then look at recommendations of hundred dollars will not buy U.S., according to insider information, this type of battery is fakes.
