Question: My original battery was DMW BCK7PP (3.6 v, 680 mAh) for Panasonic Lumix model DMC TS25. The listed battery is rated 3.7 v , 940 mAh. Compatible?
Document: This is the real thing; a bona fide Panasonic brand camera battery. It is more expensive than the off-brand replacement batteries, but it should work seamlessly with all Panasonic cameras that use this model battery. I previously purchased a much cheaper off-brand battery,Maximal Power DB PAN DMW-BCF10 Secured Digital Camera Replacement Battery for Panasonic DMW-BCF10 (Black), but myPanasonic Lumix DMC-TS2 14.1 MP Waterproof Digital Camera with 4.6x Optical Image Stabilized Zoom with 2.7-Inch LCD (Yellow)displayed "THIS BATTERY CANNOT BE USED" message after 4 seconds or being turned "ON".

I just got the spare battery. My guess, based on the current-hours and power ratings, is it will stay powered longer than the original, included-in-box battery.
These Pansonic Lumix DMW-BCF10 Batteries exhibited problems from the start and failed in 6 months of light use. Original Lumix batteries lasted over 2 years. Expected better buying factory replacement batteries. No support from Panasonic, warranty only 90 days.
Amazon recommended via email to me the Panasonic DMW BCF 10PP battery for the Panasonic Lumix DMC-ZS5 camera I purchased from them about two weeks ago, but from the reviews it is very unlikely that the DMW BCF 10PP battery can be used for the Lumix ZS5. I need the DMW BCG 10 PP battery, but it does not appear that Amazon sells it or that their partners sell it. Regardless whether it is Amazon or an Amazon partner selling the product I think Amazon should read their reviews and make sure Amazon email recommendations to us are correct, especially when the recommendation is to be used with a product they sold to us.Panasonic Lumix DMC-ZS5 12.1 MP Digital Camera with 12x Optical Image Stabilized Zoom with 2.7-Inch LCD (Silver)
Ordered this battery for my Panasonic DMC-TS3. It does not work. Turns out to be a 1000mAh, rather than the 740 advertised. Also rated at 3.7V. The camera requires 3.4V. This is not the equivalent of the Panasonic BP-BCF10PP. Don't spend the money.
I was worried that the -PP designation would be an issue given Panasonic's new firmware, but this battery is labeled "DMW-BCF10". The replacement is virtually identical to the original that ships with the Lumix DMC-TS3. I'm new to the camera, but all the reviews I've read suggest at least a battery per day you expect to leave it on, especially with all features running. I'm glad to have an authentic extra on hand.
Outstanding additional battery for my Panasonic Lumix ZS-7. Same battery as the original one supplied when purchased. Lasts for 275-325 pictures (even with GPS on).
This battery does NOT fit the Lumix model ZS7.The battery for the ZS7 is DMW-BCG10PP. Notice the "G" instead of "F" being the difference between the product numbers.I had a lot of difficulty finding the correct battery for the ZS7, so I'm hoping this helps other customers to avoid some confusion, delays, or returns.
Quality battery. It is necessary to use the genuine Panasonic battery with the Lumix DMC-TS25. Knock off batteries are not recognized by the camera, so you are wasting your money to buy them. I have not had this battery long enough to evaluate its longevity, but other Panasonic batteries I have used have performed well.
This battery is a factory Panasonic Lumix battery. I used it in my Panasonic DMC-TS2 and charged in the factory charger and worked in my camera just like the original. I bought a new camera shortly after, a Panasonic DMC-TS3 and works in that camera as well.No problems here.
Answer: The volts are fine. The 3.6 and 3.7 are only the average voltage discharges. A fully charged battery of this type will start at 4.1 or 4.2 volts. The mAh number is only telling you how many hours the battery can provide one milliamp of current before it needs to be recharged. So, the 3.7 volt battery will outlast your 3.6 volt. You may experience shorter overall battery life by charging the 3.7 volt battery with a 3.6 volt charger, however. How much shorter? I don't know... but it's probably negligible.
