FZ30 battery

On the Panasonice website they have one for sale for approx. $70.00 U.S. But other website are selling replacement batteries for the FZ30 for as low as $19.99. That price really seems suspicious to me. What do you think? Also, is it safe to buy and use batteries for this camera that are not O.E.M? Thanks for any and all replies. I have an FZ20 and I bought a spare battery off ebay. Works great! I don't remember who I bought it off, but if you put in search "battery fz-" with the "-" being your number camera, then you will get a lot of listings. Just look at the sellers' feedbacks - they are usually good. Steve I just ordered one from Amazon.com for $12.95, rated at 1300mAh, ordered last Sunday, came on Saturday, charged it up and seems to work OK in the camera, FZ-15. |

Check eBay for batteries priced about $5 from Hong Kong.

One has to beware where you get cheap batteries from because it is very
difficult to tell the good from the bad. You can even look to the Nikon battery recall for defective OEM batteries. Bad batteries not only can ruin your camera but can cause fire and/or physical damage to your body. The one good thing (and you do have to pay for it) in favor of OEM batteries is you have a reputable camera company behind them who does not want to risk their good will. But no name who knows what from who knows where does not care as they just want profit. If their name (if they have one) becomes tarnished they will just market under a different name. Something like after market printer ink but in the case of batteries they can damage your body. Jay wrote: Check eBay for batteries priced about $5 from Hong Kong. |

Thanks for all of the information. I was extremely reluctant to puchase
"cheap" batteries for the very reasons reasons you stated below. Consequently, I went for the OEM from Panasonic. While it did cost a lot more than some of the incredible prices I have seen listed, I just did not want to take a chance on a purchase that I might regret later. In any event, I have appreciated every one of the comments. "measekite" wrote in message et...

Likewise, should I worry about the spare LiIon laptop battery sitting in my bag, about 3" away from the identical battery in the laptop? Were these exploding batteries under charge or violent discharge? -- ~Dibley |

Likewise, should I worry about the spare LiIon laptop battery sitting in my bag, about 3" away from the identical battery in the laptop? Are you being deliberately obtuse? If it is in a camera or if it is a camera battery sitting in a bag then it's clearly a reasonably recent design--cameras with lithium-based batteries have not been around that long. You ship a battery through the mail, sans camera, and the inspector doesn't have any way to know whether it's a brand new camera battery or a 20 year old ELT battery. The issue isn't that your camera is going to explode, the issue is that some generic battery in an box might do so. If he has to choose between ****ing you off or losing his job he'll **** you off every time. Were these exploding batteries under charge or violent discharge? Kind of hard to be under either sitting in an ELT in an airplane tied down on the ramp. Lithium batteries were used because they had a long shelf life. ELTs don't power up until either the plane crashes or someone turns on the switch, and in either case the actual power consumed is fairly low. -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |

Unless one has experience with the older designs, the notion that a common battery might be a serious explosion hazard is novel. In all the endless flame wars over which battery type is best, I have never seen a good technical description of exactly how the Li-ion battery explosion thing works. So I Googled it. Apparently, Li-ion batteries with cobalt oxide electrodes (pretty-much all of them) are subject to a thermal runaway condition. It can be triggered by overcharging, charging too fast, discharging at too high a rate, or other unspecified sorts of abuse. Once the internal temperature reaches the threshold (one web site said "about 140 degrees F"), the cell self-heats uncontrollably. The result is a burst cell from which the "magic blue smoke" has escaped. Presumably, the "protection circuits" employed by modern Li-ion batteries act to limit the over-current conditions that could cause the battery to reach the threshold temperature. I'm not sure what they do about a battery sitting in a car trunk on a hot afternoon. I found numerous warnings from experts to not trust cheap knock-off batteries. The claim is that Li-ion chemistry is touchy and the makers of cheap batteries may have cut too many corners. Unfortunately, I don't see any way to distinguish "cheap" from "reasonably inexpensive". Other than buying a battery with a camera maker's name on it, I don't know how to be sure I'm getting quality. It's too bad NiMH cells can't match the size, weight, and power density characteristics of Li-ion cells, because NiMH's have a lot of other advantages. Paul Allen |

The size, weight, and power density advantages of Li-Ion are just three of the many advantages. The major advantages of Li-Ion a 1. Much lower self-discharge rate (except for Sanyo Eneloop NiMH batteries) 2. Higher maximum number of charge/discharge cycles 3. Higher energy density in terms of both weight and volume 4. Far, far better low-temperature performance 5. Lower cost, when you factor in the higher energy density, and the maximum number of charge/discharge cycles 6. Protection circuitry integral to the battery pack, rather than integral to the camera 7. Accurate charge level indicator due to linear voltage decline proportional to charge level 8. Lower maintenance. 9. Much better selection of higher-end cameras use Li-Ion batteries. 10. No problems with battery doors that are part of the charging circuit (battery doors are the most often replaced part of digital cameras). NiMH rechargeable batteries have the following advantages over Li-Ion rechargeable batteries: 1. Faster charging with high rate chargers 2. Ability to use disposable AA batteries if NiMH AA batteries are discharged and no charger is available 3. Longer shelf life |
