Customer Reviews
Perfect replacement for Acer Aspire 7551-7422. No more low battery indicators!
This laptop replacement battery by LENOGE turned out to be a fine choice, and was a perfect replacement for our Acer Aspire 7551-7422. The original factory battery finally stopped holding a good charge and the low battery indicator would stay illuminated at the bottom right of the task bar on the laptop. A reminder message would also frequently pop up on the screen that read "consider replacing your battery". Boy, it sure was getting old having to clear the messages from the screen while trying to complete online college courses. We had finally had enough and decided that it was time to replace the battery.
When I came across the LENOGE brand I had never heard of them before, but I was able to determine that the battery should be a direct replacement for our laptop. I also liked the look of the battery and the professional appearance of the box, indicating to me that with the added attention to detail to the cosmetics the package as a whole may be a win. I received the laptop battery quickly after ordering with two day Prime and I have been extremely satisfied with the appearance, construction and performance of the battery. Even more so now than when I was just glaring at it on the computer screen! My old factory battery was model # AS10D51 and rated at 4400mAH, while the new LENOGE battery is rated at 5200mAH. The difference in the milliampere-hours "mAH" will not affect your device, as it will still only use the mAH as needed, but you will notice that a charge lasts longer from batteries with the higher rated mAH.
The LENOGE battery was simple to replace and fit perfectly. I allowed the LENOGE battery to obtain a full charge with the laptop powered off before attempting to use the laptop. I have not experienced any overheating or connectivity issues, and best of all, the low battery indicator and frequent replace battery messages have ceased! We try to prolong the battery life by not allowing the battery to go completely dead, and connect the charging cord when the battery capacity is around 15%. Also, once the battery is fully charged, remove the charging cable instead of leaving it plugged in at all times to avoid conflict.
