Laptop needs a new battery, the current battery is 10.8v 4400mAh, I have seen a replacement battery that will give a longer run time but its 11.1v 5200mAh, would this battery be safe to use and how much longer would it last? TIA

........would this battery be safe to use .......

Yes, it'll be safe to use.

.........how much longer would it last?

In principle it should last roughly 18% longer.

While the extra voltage (10.8 volts to 11.1 volts) is unlikely to destroy any of the internal parts immediately, it will stress them and hasten their demise.

When you do get your battery sorted consider the following article (if the battery is a Li-On type): - click here

Ignore the usual rubbish posted by "wee eddie".

The replacement battery's voltage is just 0.3 volts more than the original and that's well within acceptable tolerances. And anyhow, your laptop has voltage regulators to step down the voltage to feed its hardware components.

I can guarantee that no harm will come to your laptop with that replacement battery.
