Originally posted by madbrain I have a lot of eneloops, way more than 4, which provides as much redundancy as I need.
The eneloops stay charged much longer than the Lion batteries, and I have never had one die yet in 4 years, whereas all my Lion batteries older than 2 years have died, whether for cell phones, camcorders, etc.
It appears people can get more shots with the K-r off the eneloops than the Li-on battery, too. The Lion battery takes longer to charge than the Eneloops with my MAHA charger as well.
The 3rd party Lenmar charger I got is not very good, aligning the contacts with the battery takes some time.
Given all this, I don't see a good reason to keep the charger and Lion battery. I know I would never choose to use them over eneloops.
All good points, but here's why I think you should consider having both:
- Li-ion have superior cold weather performance. Even with the advancements of the low self discharge Ni-MH's, they still can have problems in very cold weather. I guess if you never use your camera in cold conditions, it wouldn't matter......but I am always in the mountains here in Colorado and I have had issues with the Ni-MH's (including LSD's) in the cold environments.
- Li-ion are more consistent with the display on the battery gauge (though hardly perfect with the K-r I will admit).
- Some have mentioned they noticed that the higher voltage of the lithium chemistry can make a difference with auto focus, shutter, and write speeds (I would think even more of an issue the colder it gets).
- Even if you have plenty of easily charged Eneloops.....in case you have a problem with your AA adapter you would always have the lithium block to use. I have not had any trouble with my adapter, but I have seen problems with similar adapters for AA's (they are not exactly built like a tank).
I guess my overriding point is why not just keep the lithium? Here you have a unique concept for redundancy in the camera you own and it seems a shame not to take advantage of that specialty feature. Redundancy is more than just having extra batteries of the same type. The advantages of having both might come into play at some point.
Finally, whatever advantage is gained by having batteries that store longer would be mitigated by using the lithium battery as your every day battery. This would effectually negate the need for long term storage because (theoretically at least) you would be charging it often because you would be using it, true? That way you can have your long term storage champions, the Eneloops, as a true reliable backup......and in the meantime garner all of the benefits of the standard issue lithium ion block.
