What's a general rule on these? Do I have to shoot until they are flat or can I charge it when there is half a battery charge left. I'm obviously worried about running out of battery power at a crucial moment.
 
For normal penlight batteries best to have minimum 4 off - I mark then in pairs for I know which are charged. I keep a piece of blue masking tape in my bag and place a small piece on a freshly charged battery.

for proprietary batteries - spend the extra bucks and get a second battery and a car charger .... check on ebay ... they can be bought very cheap.

that way you will never be stuck without juice.


ps. the energiser 15 min chargers are the best thing ever for batteries ... i dont regret buying that thing .... expecially for xbox controller etc.
 
Li-ions are fine to re-charge whenever.
ni-Cds or Ni-MH need to be dis-charged before re-charging for best life.

You can charge Ni-MH any time as well.

To the OP, if it's the camera battery you're referring to, buy a spare and make sure that it's charged before you go on an outing.
 
And keep them in your pocket on cold days, cold weather affects their ability to provide the rated capacity.
I have a MAHA programmable charger, even though people say it's ok to treat nim-h as you please, I still give them a reconditioning charge every 2 or 3 months. They are NOT memory effect free, just much less likely than nicd
General rule here is, i treat batteries like i treat my pets... care and attention, and then you get the same back :D
*poetic*

The same is usually recommended for laptop and other 'smart' batteries. Run them down and recharge them fully periodically.

No. It is actually NOT recommended to discharge a battery completely. Batteries perform best in their top 30% range, and when you run them completely flat you run the risk of damaging them.
Keep them charged, they will perform better and last longer.
 
Correct, frequent cycling is great for batteries, they are merely chemical anyway, and yes, overdischarge == very bad. Don't discharge lower that 0.7V for nimh... anyway google for the right numbers.
OR, just use the damn things as you wish, if they last 1.5 years, then that's good :)

Just very NB, don't throw it in the trash when they are toast, recycle, or send it to me, and Ill do it, or something :(
