Contrast to the specific process of cell
NOKIA E71 two weeks to start, because the original E71 with only a 1500mAh battery laptop battery, if used normally brown on the outside is more troublesome. So mr7 in the electronic market to buy a gold dragon force brand batteries, used for E71 spare battery, of course, Li Jin Long battery life is very cheap.
The JIN Li Long battery models are J-BP-4L/e61i is for e61i use, E71 is also using BP-4L battery so common. Jin Li Long to mr7 feeling is that the use of standard battery life did not virtual (previously used to do a lot of Li Jin Long PHS batteries) are real capacity. This produced for the BP-4L battery nominal capacity of 580mAh, standby time relatively short (of course, this volume fully worthy of its price). Spent a few days later forget just modified it, buy it anyway, when the battery IBM 92P1101 Battery case is also the value of the.
E71 original battery is a SONY OEM, pick up the battery like a hand to feel of it is produced by SONY 454261 batteries, because about 454,261 batteries are 1500mAh. Apart from anything else, and quickly come up with hand SONY 454261 batteries out of the battery with the gold dragon force compare. First look at length, basically the same.
Then take a look at the width is basically the same.
Finally take a look at the thickness, or basically the same.
Installation
Use a knife to carefully cut open the wrapping paper Li Jin Long battery bonding at this time see a 580mAh lithium-ion batteries. After the wrapping completely IBM 92P1089 Battery separate, because Li Jin Long uses a 580mAh lithium-ion batteries, so the volume will be smaller points, borders on both sticky black tape to prevent the battery loose.
The Jin Li Long battery is fully disassembled, logo and check it out battery protection board. Batteries weld
The battery positive and negative and the test point identification
SONY 454261 put batteries IBM 92P1087 Battery into the Jin Li Long battery plastic box, just right. With the previous speculation was completely consistent mr7! The specific process
As the battery protection board 3 contacts the welding point was much closer, while there are around positive and negative batteries welded joints, so SONY 454261 batteries can not be positive and negative side of the shield into the same edge, we must placed on the opposite side of the two sides. We take a look at the following diagram to understand. We can put a long piece of solder batteries are negative and the protection plate is negative solder joints welded.
This is a good welding pictures, double-sided adhesive tape affixed to two pieces welded and fixed.
In addition, the best in the original plastic battery Li Jin Long both sides of the border are also labeled double-sided adhesive tape, the batteries DELL 08K8194 Battery on both sides stick to the following diagram. Also available on the plastic frame at the bottom and top cushions removed prior to the black tape used to secure the batteries.
With the wrapping paper to re-transformation of Li Jin Long BP-4L battery separate bottles, as the capacity of batteries SONY 454261 unquestionable, 1500mAh or more!
The modified cells into the E71 battery warehouse, the boot display properly electricity.
Software Testing voltage electricity 3.55V, an automatic shutdown soon.
Shutdown charge, we can see charging condition.
So much! Finally, or explain: the battery IBM 08K8196 Battery there is a certain risk of conversion, we must do a good job security protection measures. Packaging cells, especially in the latter part of this work. In practice, be careful when using the battery into the battery positions, usually the battery can not be arbitrarily placed.
