NIMH battery chargers

I have been looking at NIMH battery chargers on line. The prices I see are all over the board (from $10.00 -$130.00)

Now I know the cheaper ones did not state they had the overcharge protection in them and the more expensive ones said they "conditioned" the battery.

I know I do not want the one that does not have the overcharge protection; but are the more expensive ones that condition the battery worth the extra cost?

What would be a good value for one with the overcharge protection?

Best value for the battery conditioner type?

Is there anything else I should be considering?

i have the priranha digital peak charger. i bought it for my rc stuff, but use it to charge all my nimh batts around the house. it gives you control over type, capacity, amperage and peak threshold. it also has auto modes that analize your pack and makes adjustments during the charge.

no complaints here. well... it would be nice to charge higher voltages & lithium but i don't think that was available when i got this. there might be better chargers for the price by now though.

Look at the La Crosse BC-700 (which I have) or the newer BC-900 (with a higher range than the 700). In my opinion they're dynamite. They can deal individually with 4 AA or AAA cels and can charge, discharge/recharge, test, or rerfresh cells. I was able to rejuvinate some cells I was about to through out. Gives readout of cell voltage, charge current, and mAh capacity. Batteries can be left in indefinitely since it switches to trickle charge when battery fully charged. See 'em here http://thomasdistributing.com/shop/a...words=lacrosse.
The Maha MH-C9000 is in a similar class han I have read a good review of it. I have the Maha MH-C204F and it's been a real good one but Would like to try their new 9000 which has similar features to the La Crosse 900. Thomas Distributing handles both brands.

I have the Schulze ISL-330d . it's high end charger for my radio control airplanes.
it will charge/discharge 2 packs at once and everything from Nicd, NiMa, Lithium Ion/Polymer.A123 , Lead Acid. it's about $200.
and by the way it's the cheapest charger of this brand !! they go all the way to around $1000.
ANYHOW , i'm trying to charge those Energizer 2450 with it. and Duracell in the past. those cells are crap.
it wont Peak and stop charging. or the cell just die after short time of use.
Nothing like what i used to from my hobby with Sanyo cells. that last forever for me.
i have packs that i bought in 1999, and they still have the full capacity after who know how many cycles.
not to mention that i'm pulling high current from them and charge them fast too at 2c or 3c (means 600mA battery - charginng at 1.8A !).

my next cells going to be something like this :http://www3.towerhobbies.com/cgi-bin...?&I=LXFD86&P=7
yes the capacity is smaller , but you get 1400.00 mA ! for very long time. and you can charge them fast too.


by the way for Lithiums , i'm using the Schulze and Cell PRO 4 from FMA. the Cell pro charge the cells balanced.
but you need pack with "balancer connector" for that. i got the Cell Pro for $60 on sale.

My personal favorite is the MAHA MH-C9000 (got it from www.thomas-distributing.com). This is very similar to the La Crosse BC-900 referenced above.

I also own the MAHA MH-C801D, which will charge eight AA (or AAA) batteries at a time. I got this one first, but now use it only when I have a pressing need to charge a bunch of batteries at once.

Thomas-Distributing has pretty good sales off and on, and I got these for around $55 each. They're a little higher than that at the moment. Both will charge either AA or AAA batteries.

few more details on that Schulze charger . it will charge 1-30 cells on Left port. and 1-6 on the right port for NiCd/NiMa .
11 cells for lithium on left and 3 on right port.
Current : anything from 0.1A to 5.5A. and it has optional connector to a PC for charging/discharging graphs . it's probably way over kill for most of the people here. but if you need a charger for other things as well . it's actually cheaper to buy one that makes it all then few small chargers ....
i charge everything on it , from my model planes , to cordless drills etc

Just went with a 30 min charger from Radio Shack for $46 which included 8 NiMH batteries. Nothing fancy, it has ordinary charging safeguards.

thanks everyone for the input. i have ordered this one http://thomasdistributing.com/shop/l...ordhdlnrah3vu1.

i figured this was the best value for the money. it comes with 8 rechargeable nimh batteries (4 AAA / 4 AA). i would guess that would be about $20.00 value right there.

Does anyone know what the average delivery time is from thomas distributing? i ordered some stuff from DX almost three weeks ago and have not received it yet. (i did hear about long shipping times from DX on this forum)

That looks like a really good deal with all the batteries and other goodies included. I'd say you did very well.

I think that's a lot more value in batteries than you're estimating, too. The Eneloops alone would be at least a $20-$25 value. If I'm not mistaken, you're getting eight AA Eneloops plus four La Crosse AA and four La Crosse AAA batteries and extras. That's really a good deal to get all that plus the charger for less than $60.

Thomas Distributing is pretty quick on their deliveries, as I recall. I've ordered from them three or four times. If you got a standard UPS ground delivery, my guess is that you'll get it this week toward the end of the week...depending on where you live (assuming somewhere in the U.S.).

That is a good deal. And Thomas Distributing is a great company to order from. I'm been very happy with the orders I've placed from them.

I live in Blaine MN (suburb of Minneapolis)

Maybe by then I will have my order from DX and my fenix led Q5 flashlight from LA Police gear (finally shipped)

Glad to hear you think it is a good deal.

eneloop FAQs

How many volts are in one eneloop AA battery?
AA eneloop battery is 1.2v
AAA eneloop battery is 1.2V
What is the mAh rating of the eneloop AA battery?
AA eneloop battery is 2000 mAh.
AAA eneloop battery is 800 mAh
How long does the eneloop battery last if I use them on a regular basis?
One eneloop battery may be charged, and re-charged up to 1,000* times. Usage will vary depending on what type of device eneloop is used in.
*Estimate based on test results for battery life according to standard JIS C8708 (4.4.) Actual results may vary according to use.
How long will the eneloop battery last if I do not use it?
An eneloop battery may remain up to 85% charged if not used for up to 1 year
*Estimate based on test results for battery life according to standard JIS C8708 (4.4.) Actual results may vary according to use.
Do eneloop batteries fall under the new airline travel guidelines for lithium batteries?
No. The chemistry that eneloop batteries use is Nickel Metal Hydride. eneloop batteries are not lithium and therefore do not fall under the new travel regulations for lithium batteries. For more information on traveling with lithium batteries, please go to http://safetravel.dot.gov.
Does temperature have an effect on their performance?
Yes, temperature does have an effect on eneloop's performance. If it is too hot, the high temperature could cause the battery to discharge at a more rapid rate. On the other hand, eneloop works better than alkaline, and other rechargeable batteries in freezing temperatures!

Does this mean they are good batteries? Average? Below Average?

Looks like low average for capacity or hot weather use, but should shine brightly in their performance in the cold, and their ability to hold a charge over longer times.

I'd carry them as backups to the backups, as they will hold their charge, and probably use them as primaries during colder times.

I don't think the capacity should be much of an issue. I do not plan on riding in the dark more than an hour or two at a time. I will carry some spares just in case.

Hot weather? Don't really know what that is, haven't had much in MN this year.

They may have not been the batteries I would buy outright, but then they were thrown in with the charger so what the heck, kind of like getting them free.

EDIT: What about the 1000 recharges? Is that about what you can expect from rechargeables?

Sounds like a monster charger. I'm going to have to look that one up if for nothing more than curiosity. I have to see it.

yes it is , flying models we need to be able to charge at the field fast. and we use different type of batteries. size wise the charger is really small.

there are few more out there that are really good . another one is from ORBIT. both by the way are made in Germany.

thay are completely automatic too , you just plug the pack , and they determine what kind of battery , how many cells etc. and you can upgrade the software in them as well.
So when new technology is available the charger is not absolite .Since i bought mine i upgrade it once and now its capable of Lithium Polymer and A123(power tools).

i paid back then $160 , and i think it's heck of a deal for 2 port charger

Good call on that Thomas Distributing code!

As I recall, each time I've ordered from them, they also send me a slip of paper with the 5-percent-off code for use with my next order, but I was never sure if that was redeemable every time you do an order or not (and maybe it changes periodically, I dunno).
