I need to charge at least 4 AA's. I want something that also comes with a cigarette lighter adapter. Any brand recommendations?

I have a couple chargers from Energizer that have worked just fine. One came with a cigarette lighter adapter, but it takes a good hour to charge.
I have a power adapter that allows me to plug my other charger in with a standard plug, and I can charge the batteries in 15 minutes with it. |

| Powerex AA rechargeable batteries from Thomas Distributing are highly recommended, but it's equally important to use a charger that is able to top them off to their maximum charge. Their MH C401FS battery charger is also highly recommended. I'm awaiting my first order from them that should arrive any day. |

| I... third or whatever the Energizers. Most output for price, I got 8 for my flash power kit, like $17 at Walmart |

Just a note. I've heard from local vendors that Sanyo makes most of the NiMH batteries on the market. Other vendors like Sony and whatnot merely add their stickers.
On the subject, I've been experiencing rather poor performance from my NiMH's in that they are always self-draining. They are not cheap batteries, and I've heard that others have experienced similar effects, but my sister's 2300mah batteries don't do this. All of my 2500mah batteries do though.
2 weeks in a case or camera and I've got a dud.
Kinda disappointing considering if they are fresh, I can get more than 700 pics on a single charge with my camera and I bought this camera over the FZ20 because of the batteries... Grrr.... |

They don't hold a charge real long, but if it's down to no charge after 2 weeks it's defective and you should return them. I know Batteryspace.com is real good about swapping them out if you get a dud.
They advertise they hold a charge for 60-70 days, but that means it has a half charge after about 30 days. I always make sure to charge them a day or two before I use them.

I was in a bit of a hurry, so just went out and bought an Energizer charger (which came with 4 AA's) and 8 more AA's. I just opened the package and learned that it take 3.5 hours to charge 4 batteries. For the $60 I paid, I could have bought a similar package that charges in an hour from Batteryspace.com. I guess it does pay to be patient.

Back when I was working at the Garage back in Canada, the mechanics all pretty much agreed that it was better for a battery's long-term life to be slow-charged. I don't know much about NiMH technology, but I would imagine that this principle is pretty much the same.
I charge my batteries overnight myself.
Louddog. I'm afraid that returning batteries isn't much of a possibility for me. I live in Taiwan, and return policies are a bit different here. I have 2 sets of 2500 mah batteries and they are both the same, so I don't think it's a defective issue. I alternate using them, but usually charge one set at night and the other set go in the charger in the morning.
It could just be that my memory is at fault and what I thought was 2 weeks was actually 3 weeks or a month.
I just thought it was odd that the batteries I keep in my bag were completely dead when the batteries that I had in my camera were still able to take 175 pictures. I had taken 150 pictures a couple weeks previously with them. (or was that 3 weeks?) This happens to me a lot.
It is interesting that you mentioned that they hold their charge for 60 days.
A device knows that a battery is dead by the decrease in voltage. Typical AA batteries produce 1.5v. NiMH's ALL produce 1.2v. While the charge is very durable to load, when the battery drops, the voltage does too. 1.2v nominal is much closer to 1.4v actual when charged fully. This is quite close to the drained voltage of a standard AA battery.
Few devices take this into consideration and optimize for lower voltages, mostly because this is a MAJOR redesign of operating specs and might necessitate a voltage booster (and subsequent heat buildup and loss of efficiency).
This makes sense that with a 60-70 day actual charge drainage, such batteries will be unable to deliver sufficient charge at half full (or 2 weeks) to be recognized as not empty by the camera.
I hadn't heard the figure of 60-70 days before.
The oddity remains as to why idle batteries seem to discharge faster than batteries that are in the camera (presumably running the clock and whatever). |
