it depends on what type of batteries...

for SLA battery, you can't let it totally flat out, it will be dead forever if you do it that way. charge it full after used, and charge it every 3 months if not in use.

for Li-ion battery, use on most cameras, always keep it fully charge will help prolong battery life.

for NiMh batteries, use on flashes, since most of them won't retain power very well, charge it before use, and run conditioning charge and discharge periodically.

Since they are based on different technology you can't treat them all in the same way. Camera batteries are based on Lithium-Ion technology, AA types come as NiMH or NiCd (very old ones) and maybe as Li-Ion soon as well. Only NiCd batteries suffer from 'memory effect', all other batteries basically can be charged whenever needed, independently from the current charging level. Use the respective chargers and follow the instructions for charging, refreshing and formatting (only NiCd). Although NiMH don't have this 'memory effect' it's a good habit to discharge them once in a while using the refresh function of many chargers.
As catchlights pointed out: camera batteries (Li-Ion) cannot (and must not) be drained totally. The camera will stop working below a certain level (indicating the lowest possible discharge point). If you try to discharge further you'll damage the battery. Charge them soonest and keep them charged.

I usually...

1. Put the batteries in the charger.
2. Turn the power on.
3. Take off the batteries when the light turns green.

Hahha....

Ok, seriously, I charge when the batteries are weaker, like when they show 1-2 bars after using for some time on my camera (For the Li-ion camera batts) and when the flash cycle time is slower (For the NiMH AAs for my flashgun).

Li-Ion battery must not be drained totally? you mean using it for shooting till it fully flat? So i have to charge it if it shows 1 bar?

What does it mean Li-Ion cannot and must not be drained totally ?

after each shoot can charge liao

i'd charge it if it's less than 80%. sometimes i shoot a few things ard the home, use only 5% or so, i just dun bother to charge.

there's no need to drain lithium batteries before charging. in fact, deep discharge (draining more than 60%) should be avoided.

Cannot - the camera (or any other device using such batteries) has a built-in discharge control. Once the voltage goes below a certain level the camera switches off (although maybe there is still some charge left for 10 shoots or so).
Must not - some people try to be clever and use some lamps or other stuff and connect it to the battery for deep discharge. Sure way to spoil your battery and get a new one.
Chargers have integrated checks and meters to determine what needs to be done with the battery.

Mind the difference between "charge of a battery" and "voltage".

draining batteries is due to memory effect which is no longer the case with nimh or newer rechargeables.

Just plug into charger whenever free.

hmmm, if that's the case, why would people want to use batts that (operate and achieve best perfomance/lifespan) shouldn't fall below 60% charge level?

kind of pointless to have a batt still have 60% charge but not be able to use it for fear of spoiling it right?!

the batts that come with your DSLRs are Li-ion, and the rechargeable ones (ie eneloop, energiser, ikea rechargeables, etc) are NiMH right?

what about handphone batts?

using it accelerates the wear and tear, but if u need to use until "empty", just go ahead ;). equipment is meant to be used, not babied. but of course if one is a light user, no point pushing the limits of one's equipment, right?

li-ion batts will cut off the power below certain voltage. low batt means it's used until the safe level liao.

60% (or thereabouts la) is the optimum. i.e., if u shoot very little, try not to let the battery drop below that amount. reach abt 80% can recharge liao. wanna recharge at 90% also no issues.

if u are shooting a lot and drain the battery, 60% or not, ur battery will have wear and tear, like most other components. so u will have to replace the battery eventually.

for long term storage of li-ion battery, it's another story. drain til abt 40% then store. apparently not so good to store it at full charge. storing means a couple of months i guess?

i was reading up on wikipedia after i saw this thread, so if u want the info from the source, can go take a look :)

hp batts these days use lithium. about 8-10 yrs ago, i remember some with NiMH batteries :bsmilie:

i think the most "recent" model with NiMH option is the nokia 3310. cos i used it for some time. NiMH noticeably heavier, but somehow can last longer. not that it matters. this is getting OT

Can i charge my eneloops anytime?

Sometimes I try to drain them by putting leaving "on" on torchlight. But someone mentioned it's not the right way.
