BM Premium 2 Pack of DMW-BCM13E Batteries for Panasonic Lumix DC-TS7, DMC-FT5A, LZ40, TS5, TS6, TZ37, TZ40, TZ41, TZ55, TZ60, DMC-ZS27, DMC-ZS30, DMC-ZS35, DMC-ZS40, DMC-ZS45, DMC-ZS50 Digital Cameras

The fit and function for my panasonic camera is great, holds a charge well, and for the price compared to the factory battery, is much better. Now I can have both batteries charged, so if one dies, I have a spare. Fast shipping too.

It seems to be Panasonic's bad habit to market spare batteries for their new cameras MONTHS after the camera's release. I'd been through this with other Panasonic models, and wasn't exactly surprised when I began looking for spares for the ZS30 and couldn't find any originals. It must have been bad timing on my part, but when I needed spares, the only available ones on Amazon were Big Mike's.Cameras with built-in GPS drain batteries quickly and I knew that (I wanted the GPS, so turning it off wouldn't be an option). I was on a deadline, my forthcoming trip looming just ahead, so I decided to risk it and bought two. To my surprise, Big Mike's batteries actually lasted longer on my ZS30 than the original Panny battery that shipped with it!Unfortunately, at the time nobody on Amazon was selling external chargers for the ZS30. I absolutely HATE the in-camera charging system so many manufacturers adopted because it is such a hassle: insert empty battery in camera, plug camera to laptop or wall, charge, remove full battery, insert another empty battery, plug camera... But during my trip to Japan, I found an external charger (NOT Panasonic...) that worked with the BCM13E, which enabled me to have full spares at all moments of my trip.Big Mike's really saved my day.

Good product.

I purchased these before leaving for a vacation so that I did not have to worry about running out of battery power while out for the day. I would charge them overnight, then use them during the day. As long as I charged them every night all was well. They would power the camera the same as the one it came with. But beware - after sitting off charger for a while (read: a about 3 weeks after vacation) - they lost their charge. The original battery did not do this. The original battery is 5 years old and still holds the charge for several months without use (I'm not exaggerating, I prove this) but these batteries lose their charge over time.

The batteries and charger for my camera were getting old. The batteries were not holding their charge very long and the charger was getting very sensitive about engaging after being plugged in. I at first had trouble even finding the right replacement batteries. I found them and the charger on Amazon. They were everything I hoped for in their function, and the price was great.

These batteries work fine - but I am disappointed with the product life. I feel I should have gotten more pictures for each charge of the battery, and I find myself changing batteries too often.

I have a Panasonic Lumix TS-5 and was hesitant to purchase off-brand batteries. After reading reviews, I went with Big Mike's, and the two-pack of batteries worked better than anticipated! The batteries fit the camera perfectly, worked in the stock charger exactly like the Panasonic brand battery, and the juice LASTED! One fully charged BM battery lasted for a full day+ of vigorous photo shooting. I filled 32GB in 3 weeks, and never had power issues(:

I was using these batteries just for a few months, and so far they are working very well, practically like the original one when it was new. I will try to update my review in a few months later.
