New laptop battery required....

Nope, the battery can be removed and replaced easily without any losses (assuming you mean the main battery).
If you mean the battery on the motherboard that's the same as long as normal care is taken ... power off, remove main battery, discharge any residual power by pressing and holding the power button for 10 secs and use an antistatic wrist strap or ground yourself before touching anything. :)
 
No problem, won't affect your data at all - as a precaution just make sure your laptop is switched off and I would remove from the mains before you do it, then simply swap the old battery for the new one. :)
 
Can we assume that you do not back up your data? Sooner or later all mass storage devices fail.

The 11th commandment - Thou shalt backup till thou art blue in the face with backuping.
 
If the data is backed up, the only thing you might lose is any pre-installed software (doubtful in your case.)

What Laptop is it? I have some spare from my dead laptop which failed on me last month (a HP Pavillion)

Why would he loose anything?

Peter is only changing the battery

If he follows @gramps advice in previous posts he should be good to go
 
Lets say the battery you have just bought is poorly made and not QC'd; in a very unlikely - but possible - scenario, it overheats significantly when charging due to a faulty voltage regulator and eventually catches on fire - boom, data gone.

Never take chances with data.

Sorry, I didn't mean that. I was following up on the general advice to back up data. Then the only thing you could lose under any circumstances might be pre-installed stuff. I didn't mean to suggest that changing the battery might cause any loss.

Or just plug the existing battery in on a train socket ;) the action of changing the battery or not has nothing to with the risk of loosing the data. Not having a current back is what is the risk.

Heck for some machines in the past I always carried a second or third battery. Even done some hot swap - not recommended unless explicitly supported by the manufacturer - and kept the machine running. It will not loose stored passwords or anything.

Correct! - and that is why I tried to verify that the external drive the OP uses is an actual backup of the laptop contents. If it isn't I would be very afraid of doing anything with the laptop until I have a backup. (admittedly putting in a new battery is very low risk, but not risk free)
 
Switching the laptop on is likely the biggest risk :)
