Many friends worried about buying refurbished machines, or to buy new aircraft equipped with the battery Laptop Battery is really old! With JS refurbished technology innovation, a lot of identification methods have been invalid! There are several simple and effective means of checking the phone is purchased as a refurbished machine or battery-Wai, whether the old batteries, and oil to share next! (1) look at mobile phones
1, shell. The new aircraft shell bonding compact slit at smooth, no glitches. Refurbished machines generally use the fake original shell, slit at uneven, there are glitches, cell phones vulnerable to the two parts of the upper and lower case is not closed tight, leaving a great gap phenomenon. Identification with a small finger nail can be inserted into the phone try to cover the upper and lower joints. If we can insert in the first is the refurbishment of aircraft. The new aircraft, like the surface of the Acer BTP-550P Battery shell, like frosted, and there are small particles of mobile phones, but also must not buy.
This machine is a JS spray paint the shell up, and over time, paint will come off (small particles of dust on the chassis is a painting without a job created by a vacuum environment); the present moment more than a means of refurbishment for re - Spraying shell! This cost should be lower, but the re-spraying is bound to lead to the next and the next shell screw! This will inevitably leave a mark in the screw!
2, the new machines turn covered with a hint of sandalwood smell, if refurbished machines, JS generally carried out some of the fuselage Acer BTP-73E1 Battery beauty, despite the smooth appearance, but not dry, turn the battery cover or remove the rubber smell after, plastic taste , or the smell of chemicals!
3, data line interface (focus). As the charger plug, data cable plug a long-term reasons, the renovation of machines charging interface will appear difficult to eliminate the black scratches. This is the identification of the main points! JS is difficult to refurbish cell phone interface and the data-line charging interface welding swap new! Increase the cost of doing so do not say! Have requested the operation, after all, can not be original than the welder's! JS not generally reluctant to take such a risk!
4, SIM card chip contact (focus). The following figure:
This contact is generally impossible to Acer BATCL50L Battery replace JS. If it is refurbished machine, then the contacts on the SIM card chips will leave clear traces of friction, it appears bright, which is caused by excessive friction. If it is new aircraft unused chips, then the contact surface should be brushed; 14 secret will appear SIM card contacts wear and tear, however, far less! Even if the 14-day process of using SIM card once a day and can not plug a serious wear and tear marks!
5, fixed screws. (Focus) mainly to see the screw and the knife-edge interface, there is no obvious scratches parts, internal display whether or pick the bottom two pad marks. This is the repair or renovation can be a result of the situation!
6, the price. As the refurbishment of aircraft spare parts, mostly the early product, quality is also poor, the price is also low. If I run across low price to be outrageous Acer TravelMate 290 Battery and merchants known as parallel imports of mobile phones, it can be concluded for the renovation of the basic machine.
(2) The battery is a point of identifying the main points of contact: the following figure:
The new contact for the frosted surface! Without any trace! If it scratches! While most Acer TravelMate 4000 Battery minor of 14 secret cells, severe scratches can be judged to be old batteries in! Other identification methods have been largely JS technological innovations to eliminate the
