No set answer to that. It depends on charger output and battery capacity. Usually a few hours.
A set of NiMH AAA batteries can last roughly a month on a full charge if they are not being used at all and are simply allowed to sit around. In devices such as cameras and small pda's where rechargeable batteries are best used, the batteries can last nearly as long as normal alkaline batteries on a full charge. Exact times depend on the capacities of the NiMH batteries. A charge lasts long enough for a camera to be used normally for several days and hundreds of shots. As long as the NiMH batteries are not allowed to be idle and self-discharge, the life of a single charge is almost as long as a full alkaline battery. The life of the battery itself can easily be several years. NiMH batteries don't need much maintaining and can last for hundreds of charge cycles.
It takes about takes approximately 220 minutes to charge four NiMH batteries with the Canon 6872A007
If its a NiMH battery then yes. The Energizer charger will charge ANY brand of NiMH rechargeable batteries.
Rechargable NiMH batteries will have memory issues, but are so cheap it's often not an issue.
Packs,yep..
Some will, but it is not recommended because it can damage the batteries or the charger. Invest in a NiCd charger or better yet get some NiMh batteries. NiMh batteries are better than NiCd in every way.
BTY AA NIMH Batteries: The BTY brand of NIMH batteries that are being sold on I had had received merchandise that matches exactly what they advertise.
The AX-Synth does not recharge the batteries. You have to get an external AA Ni-MH charger.
NiMH batteries are the longest lasting.You need to get a quick charger if you want to charge them quickly.That's more important than the batteries.
Not significantly. So long as it is done using a properly designed smart charger, most NiMH batteries can be recharged in about an hour without any damage or significant reduction in their life. However, NiMH batteries must only be rapid charged with a charger specifically designed for charging NiMH batteries. Chargers designed to rapidly charge NiCd batteries can overcharge NiMH batteries. While it may be true that rapid charging NiMH batteries can reduce battery life by a small amount (probably less than 10%), this should be more than offset by the inconvenience of always slow charging batteries.
I doubt you'd find one ! NiMH batteries charge to 7.2 volts NOT 9 volts ! Trying to charge one to 10 volts is overcharging by almost 50% ! This will certainly shorten the life of the battery and COULD result in overheating and/or explosion !
The NiMH battery is better,but it's more expensive.
