Common Household Battery Chargers Powered by 12 volts

[rockDAWG]

Glad I can help EOTR

The smart charger I mentioned is great. It charges each battery independently depending its own state of charge. The non smart charger charges the battery in series of 2 or 4. As such, it can easily damage the battery by overcharging them. Over charging and charging rapidly are the most fatal to the rechargeable batteries.

Costco has the best price for Sanyo Eneloop if you find them for sale. They have two types. One with a charger, one without. I buy the latter.

Ok, now I'm getting charger envy.

Rockdawg,
I just ordered the charger and 3-four packs of aaa batteries on amazon for $61 free shipping.
Thanks

One important diff between alkalines and NiMh (and some other rechargeables) is that alkalines are 1.5V and NiMh are 1.2V. Some devices don't like this and some will reach a low battery state much sooner.

I've used the Tenergy charger below for a few years now. Has direct 12V or AC adaptor input. Also really like their high capacity batteries.

Update,
I'm not overly satisfied.
I'm not getting the hours I should be getting out of the batteries.
I'm not yet sure if it's the Sanyo batteries or the charger itself.

I have the Eneloop batteries and love them! Did not find a single negative aspect about them.

I use two types of chargers: the small one that you can get packed with a 4-pack of the Eneloops and a big one for 16 batteries that looks like a double version of what you have.

I thought you got the Eneloops? and that charger really looks like it has the same internals…

Another Eneloop user here with ZERO problems. Class act AAA/AA battery. I use a LaCross charger. The meter shows they charge to about 1.48 volts before reading full.

Yeah...I feel confident about the eneloop batteries but the Hi-tech brand charger might be the problem.

Maybe it's me?

The batteries are fully charging according to the charger but the charges are about 60 percent of store non chargeables.
Does this sound about right?
Am I expecting too much from rechargeables albeit Sanyo eneloops?

Sounds like maybe your charger has an issue...it is reporting full before it is really complete.

Yes,
The bars show the gradual charging of the batteries to full and then the bars stop blinking indicating fully charged according to the users manual.
I even used the discharge option and then fully charged a set of batteries.

I'm only getting about 50 percent usage out of my Sanyo eneloop batteries compared to a conventional battery.

You might want to consider a new charger. My La Crosse BC-700 charges each cell individually. I have not had a problem with it taking out any of my Eneloops regardless of charging input. I am not a real fan of chargers requiring cells to be paired up. When I used one, I would usually use my multimeter to pair the cells with similar discharged voltage.

If you keep an eye on Fleabay, you can get a decent charger at a decent price.

Although it was highly recommended in this thread by another member I'm assuming that anything called "high-tech" is garbage.
The fact is, it can't be 12 Sanyo eneloop batteries that all are weaklings, it must be the hi-tech band charger.

I have the La Crosse charger too… more geeky, more settings, but end result is equally good. I love it to see 16 batteries charging simultaneously, each on it's own charging circuit!

In my camera flash units, they outperform batteries like Duracell easily. But for other, less demanding tasks, I can see Duracell outperforming Eneloop. But not by 100%.
