I imported the standard axle E300 in 2010, and the auxiliary battery was finished. The first time was two months ago. I took it down and bought a battery reparer to be rescued. I have to replace it this time. Without talking too much nonsense, I will just go to the picture
I have been diving for a long time, but I have never found the exact size of the auxiliary battery. I will send one first for your reference.
Remove the headlight switch first, turn it to the P position and press it down.
Press and twist clockwise.
Remove the three screws under the instrument panel
When you want to remove the lower cover plate, remove this screw and unplug the foot lamp plug, the air flow device plug, and the computer plug in turn. However, I removed it the second time, but I didn't think it was necessary to remove it because the screws were very hand-held when installing the cover handle and it was difficult to put on. Just open the board a slit.
Remove the left cover plate and unscrew the only fixing screw to remove the auxiliary battery.
I didn't buy the original battery because I thought about it and estimated that they were all fake or renovated. It was not as good as the brand's new products. The most important thing was that they were cheaper.
The length and height size are the same, but the width is slightly smaller. It doesn't matter that a rubber pad is added to prevent abnormal noises
The only thing to note is that the positive and negative electrodes are positioned opposite to those of the original factory. Don't connect them incorrectly.
Successfully completed, everything started OK, Chaowei battery's working environment is minus 40 to 70 degrees, and the cost is 50. Just ask not to leak liquid. Please advise Yan Ban.
