To ensure the optimal performance of your IdeaPad, you need to replace your aging batteries regularly with new, high-quality laptop batteries. Compatible with the IdeaPad U450 and U550 model series, our high-quality lithium batteries are manufactured new and undergo rigorous testing to guarantee the batteries meet or exceed OEM specifications. The ThinkPad compatible batteries feature six Grade A li-ion cells with an 11.1v output and 4400mAh power capacity. The high-capacity ensures your device has long usage times. Since the batteries are completely OEM compatible, the batteries can be charged with a standard IdeaPad AC charger.
Although our IdeaPad U450 and U550 compatible batteries, many times, outperform the original battery, our batteries are nearly 70 percent less than the original battery’s cost. Replacing batteries is a necessary purchase, but it doesn’t have to be an expensive one. To ensure complete customer satisfaction, our ThinkPad replacement batteries have a 30-day money-back guarantee and are protected by a one year warranty. For extended coverage, a three year warranty is also available.
