Does anyone know ..

 

are the batteries for these 2 cameras the same ?

are they interchangable ?

is the charging unit the same ?

is the charging unit interchangeable ?

 

i ask this because a house guest has his digilux 3 and i have my digilux 2 here and we don;t want to exchange batteries by mistake and short out the camera or do any damage

 

thanks

The D2 battery has slightly less capacity than the D3 battery (1400ma v. 1500ma) but either battery works fine in either camera.

I have two Digilux 2 batteries which I alternate but how far should you run down the battery before re-charging ?

I used my friend's D2 charger for a week on vacation in Italy last month, as I'd managed to forget to pack my own. I had no problems. He has used my charger successfully as well. We've not tried swapping batteries.

Personally, I run 'em down until the power meter on the LCD starts to blink then swap them out.

 

From How to prolong lithium-based batteries:

 

"Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate.

 

Aging of lithium-ion is an issue that is often ignored. A lithium-ion battery in use typically lasts between 2-3 years. The capacity loss manifests itself in increased internal resistance caused by oxidation. Eventually, the cell resistance reaches a point where the pack can no longer deliver the stored energy although the battery may still have ample charge. For this reason, an aged battery can be kept longer in applications that draw low current as opposed to a function that demands heavy loads. Increasing internal resistance with cycle life and age is typical for cobalt-based lithium-ion, a system that is used for cell phones, cameras and laptops because of high energy density. The lower energy dense manganese-based lithium-ion, also known as spinel, maintains the internal resistance through its life but loses capacity due to chemical decompositions. Spinel is primarily used for power tools."

My wife has a cheapo Panasonic and (this week...) a D-Lux 3.

 

The batteries are identical in size, power output, voltage, colour. Everything.

Andy, I believe you have mis-understood the models of cameras in this thread. As the D-Lux 3 battery is quite different to those of the D2 and D3 mentioned above.

thanks all for the responses.....

 

my main concern was doing damage the camera 9either or both) and now i feel comfortable if something get switched it won;t be catastrophic.

 

thanks again
