Sony FZ190 battery back from the dead?

Is it possible for a Sony FZ190's battery to come back from the dead (Battery Bar utility indicated that it had no charge or was missing; could only run on AC power)? Earlier today I initially could not start the Sony even with AC (battery light blinking, green power light on only when I held power on/off switch down, would go off if I stopped pressing).

I took took the battery out and re-installed (had done this previously when replacing hard drive about a month ago; battery was assumed dead at that point too). When I plugged AC power back in and pressed power on, it started up like normal (running Windows 7 64 bit).

The Battery Bar indicated that they had a new version. I updated this (now version 3.3.2) and it now gives additional information on the status of the battery. I did a double take when it not only showed that the battery had some charge, but also appeared to be charging. It appears to be charging even though Battery Bar does not show a charge rate (eg. shows 0) and the battery wear is about 12%. As time goes on the charge level has steadily been increasing (from 25% to now just over 81%).

I had assumed that I needed to replace this battery. Now I am not sure if the problem is the battery or something in the charging system. If it is the later, I don't want to buy a battery if that is not the problem.

Attached is a screen shot showing the Battery Bar status.

Any suggestions?

 

This Sony FZ190 has the original battery (eg. 3+ years old) and had the charging plug adapter (eg. where AC cord plugs into notebook) replaced about a year ago. It was charging battery after that repair.

 

Well, my e1405, when I got it, would die immediately if you unplugged it, and would not even try to power up unless it was plugged up to the adapter.

So, I ordered a battery from ebay, and the very next day, my battery came back to life. Granted, the wear level was 40%, but it would at least stay running while unplugged.

Short version: Yes, it's possible.

 

mnrat,

just want to add that Battery Bar Pro, while I was demoing it, showed a 2% decrease in the batteries life (VAIO) where this computer has been in use for 1 year and did not show anything of the sort. When I tested the run time on battery power, it was down nearly 20 minutes - needless to say, I uninstalled Battery Bar Pro and my run times are back where they should be - except that HWMonitor does show it as 2% degraded too.

On which I'm blaming Battery Bar Pro for.

Somehow, I don't trust that program.

 

You probably don't need to buy another battery unless you require a mobile laptop, but either way batteries start to deteriorate the moment they are manufacured. The chemistry behind Li-ion batteries is such that they have a limited number of recharge cycles and a limited shelf life.
