Title: When to recharge batteries...
Post by: The Foster Bear on January 24, 2012, 06:48:22 AM
I have the GPSmap 62sc. The batteries now are showing 1/2 charge. Are these like the old NiCAD batteries that need to be run to zero before recharging? If I recharge now, will I loose capacity on the batteries?

Thanks, The Foster Bear

What kind of batteries are in your GPSr?

If these are new rechargables you should be good to go to recharge.  However, all the batteries have a limited number of recharge cycles.

The batteries are marked Rechargable NI-MH Battery, 2, AA size. Make is NEXcell.

I asked because our Preservation Society camera needs a replacement since it won't take a charge. It is a Sony which is unique to the camera. They keep changing the battery configuration. It is no longer carried in any stores and I have to send away. Cost is $53.

Thanks for the reply.

If I read this correctly, the Nickle Metal Hydrid batteries your trying to use will acquire a memory -- that is if they are only partially charged, then in the future they may only partially charge. These batteries were our worst pain in digital cameras and to fix this I would recommend you use Alkaline batteries. We gave up on NI-MH penlights a long time ago because of this. For one, if your battery dies they are easily replaced and even if your out you can buy a new set at a local mini-mart you'll be ready to go, where as you may not be near a power source to recharge the others. The other bad thing about them is they won't hold a charge, usually only having a shelf life (that is to hold a charge) of 30 days or less. The newer lithium batteries that everyone is going to can hold a full charge for at least a year, and take many more charges than the NI-MH batteries will. You can always carry a few extra AA Alkaline batteries with you.

Hope this helps,
Don....

There are no AA size rechargeable lithium batteries available.

In you first post you say they are Ni-Mhs which do have a finite life.  If you want to continue to us  NiMh batteries, I recommend that you go to Imedion battereis.  I use them in my Dakota and they rock!  Their unique chemistry allows them to hold 90% charge about a year.  they do extremely well in cold, too.

What are you paying 53 bucks for???

I am a big fan of the sanyo enloop batteries; they seem to have the best life and aren't very expensive.  they also hold a charge for a very very long time.  Sanyo Battery Starter Kit (http://www.amazon.com/gp/product/B003VLAEPQ/ref=as_li_ss_tl?ie=UTF8&tag=gp068-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B003VLAEPQ)

I also got a sony battery pack that does "smart" charging where I can refresh my existing batteries (complete drain and slow recharge, makes them healthy again).

I also use the SANYO eneloops, and use one of these (http://www.maxpedition.com/store/pc/Volta%E2%84%A2-Battery-Case-7p581.htm) in the field to hold extra AA & CR321 cells

I've also been very happy using the Sanyo Eneloop batteries.
Excellent at holding a charge on the shelf.  Also seem to outperform higher capacity batteries I have used in terms of battery life ( ie. runtime on the gps) for a fully charged cell. :)

FWIW, I tested/have Eneloops and the Imedions and if you like the Eneloops, you l will LOVE the Imedions.  They perform even better in my tests.
