rechargeable batteries Does anyone know if you can put different batteries into different chargers? I have a 15 minute charger unit and it says that you can use other batteries for it, but my question is..can I use duracell rechargeable batteries (which usually take an hour to charge)in this rayovac 15 min. charger? will this work or do I have to stay with rayovac batteries

Welllll, some batteries will accept a quick charge, others need to be trickle charged. You could try one and keep checking it to see if gets hot. If so, stop charging it in the Rayovac. OR, go to the Duracell website, drop them a quick e-mail and ask them, but be prepared to give them the charging specs on your Rayovac charger. Best answer I can give ya Sherry. Someone else here may know more about the Duracell rechargables and whether they'll tolerate a quick-charge. Mark

Thanks Mark.. do you know. can batteries and chargers be interchanged with each other when they are not from the same company?

Sherry; Any battery can be quick charged. Slow charging and then trickle is much healthier to a batteries life. If you are using Ni-Cads, be sure to charge them fully as they exibit memory..(i.e)..They may not take a full charge if you don't allow them to discharge completely, or remove them from the charge cycle too soon. Lithium-Ion batteries do not exibit this problem to the same degree as Ni-Cads. Yes..You can interchange batteries and chargers as long as you stay with the same type. Pete

Actually Sherry, I don't think all batteries will accept a quick charge. Although you can try it, whether it works or not and whether the battery retains its voltage AND amperage, depends on the battery type, its condition, and the charger. Also, some chargers are made to accept AA, C and D rechargables, including the one from General Electric that was (and probably still is) sold by Costco and Radio Shack, as I recall. And you can charge AA's at the same time as say a pair of D batteries in that particular unit. You just need to do them in pairs on that particular charger. What Pete was saying is true in that if a charger is specifically made to accept only one size battery, then no, you can't charge another size in that charger. And, whatever you do, don't try to recharge a depleted alkaline battery. That could be hazardous. As I said, the best source of information is to contact the manufactuer tech support by e-mail. Just tell them exactly what you're trying to do. Take it light.

Chargers are specific to the type of battery, i.e., NiCad chargers for NiCad.; NiMh charges for NiMh (can't use this for NiCads). Alkalines are not rechargeable. Most chargers have adjustments to switch to AAA's from AA's. NiMh are great. They hold the power longer, you don't have to fully discharge prior to charging. Choose the highest "mAh" like 2500. Someone explained to me that they have a lower voltage rating (1.2V) compared to Alkaline batteries (1.5V), the voltage stays longer at the same level, which is important for dslrs. Also, try to keep them warm. Hope this helps.

Just to add to what everyone has said, I don't believe Lithium-based batteries can be "quick" charged. In fact, if a lithium battery goes below a certain voltage, I think it has be be charged at an even slower rate until it reaches a particular voltage and then can be charged at a normal rate. The advantage to lithium batteries is that they can hold a huge amount of electrical current relative to their size ( i.e. more power in a smaller space ).

Thank you to all that have helped me out. I now further understand how these rechargables work. ***THANK YOU**
