12 Cell Laptop Battery for HP Pavilion DV4 1543sb
on August 19, 2013
The 12 cell battery is deeper in size. It fit perfectly with a snap and protrudes about 5/8 in beyond the base on the laptop making a comfortable tilt. The battery lasts around 5 hours with normal business use. It arrived within 5 days! The directions for initial use were helpful suggesting to charge fully, unplug, discharge as much a possible below 9% and repeat 3 times. Then continue to use laptop unplugged until battery is 30% before connecting to power to recharge. Very helpful. If you want the best battery life possible, do not use the laptop plugged into power with a battery at 100%. Only plug into power in battery is removed or it is recharging. I recommend!
The only improvement I see would be that the vender state the full model number on the laptop. I wasn't sure it would fill my 1543sb.
