Dear All,
advice would be much appreciated. I purchased a new K-7 January '10. Not much use - only about 1800 actuations. Now the battery is failing after about 150 shot and needs recharged. Camera just jams and dies- although LCD disply remains on top - even when turned off. Works OK when recharged, but only for another 150 shots or so
Is this a faulty battery and should it still be under warranty? Just checked - £60 to replace.
Thanks in advnce
Michael

you charged it properly, right?

so that means fully charging, fully discharging, and repeating that for *at least* the first three charges?

Storage for long periods in a fully charged state? If not, you've broken it and you can try arguing for a new one, but I wouldn't bet on it....

Never heard of that before for 'Li-ion' batteries :

Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge.

How much do you use the LCD screen? Live view and lots of reviewing will deplete a battery quite rapidly.

If the LCD display remains, you might have a fault with the camera. When the battery dies, everything turns off.

If you know anybody doing electronic work, you can ask him (her) to do a load test on your battery BEFORE and AFTER the camera dies on you, so you'll know for sure if you have a problem with the battery or the camera.

Is the firmware up to date?

Thanks to all for the comments - very much appreciated. Battery was fully charged/discharged. Firmware up to date. Not covered by warranty. Looks like I need to replace. Better luck next time.
