Your gonna need some batts for them damn toys!

If you needed AAA you might as well keep them, there is no such thing as a 1850 AAA, it's not like you will do much better paying for return shipping and then buying a different AAA.

Actually BUy.com is paying the return shipping and I found 1000mah AAA's at Thomas-Distributing but I want to see if the pair of 750mah batteries will work ok in my mp3 player (my 600mah batteries were drainged in about 30 seconds, but htey were old).

Costco has a deal with 8 2300/2350 AA's, and 2 AAA's, with the charger for right around $20.

That's nice of buy.com

Beware of off-brands with lofty capacity claims, typically maha/powerex or sanyo have the best capacity and they're not up to 1000mAH AAA yet, AFAIK, which makes a generic cell with such a claim very dubious.

This deal might be hotter than most people think. I've found the higher rated batteries tend to have a MUCH shorter useful lifespan than the lower rated batteries. Most of my 2x00mAH batteries have lost a great deal of their capacity within a year.

I've noticed this as well. It seems that in the competition to have higher MAH ratings they have shortened useful life of the batteries over time. So they test well for reviews but later you suffer. I don't know, could be my imagination.

In addition the other comment about the skin peeling off and such, they aren't as high a quality as the name brands in that regard. Again, as mentioned, for Kids toys they're probably allright.


That said, for the price I think the batteryspace stuff is decent and I would buy it again.

Last note, some kids toys (and electronic devices in general) don't like the lower voltages of the NiMH/NiCD batteries (1.2-1.4v per cell) vs the 1.5-1.6v of Alkalines. Also, NiMH batteries drain (I think like 1%/day) even when not in use so if it's a pain to change the batteries sometimes Alkaline are still better.

All that said, I still use NiMH for 90% of our household items but after buying all the cells and all the electricity to charge them the last few years I'm not really sure I've saved anything yet.

Unless you bought an excessive (-ly expensive) charger, you should have recouped the cost of the cells in a couple month's time, three or four recharge cycles. Typical generic AA cells are $1 each in bulk and after about three recharges it's all savings, you've already exceeded the capacity of same $ in alkalines. Electricity cost is trivial, you probably don't spend $1 per year on power to charge them.

If you want rechargeable batteries, get the 8 +4 Energizer overnight charger pack from Sam's for like $22 bucks. The AAAs are 850 which is very high.

 

[Ryland]

I don't need another charger since I have a nice MAHA charger. I just needed a few AAA's but found 2 in a flashlight I had which may work out fine.

 

[datacomm]

Agreed,MWink.

Cells with high capacity will run through fewer cycles than the lower capacity cells before capacity loss really begins to set in and finially....failure

I've also found that 2x00 mAH seems to be the cutoff point.

Like most things in life, there's always tradeoffs.

I need more batteries...just a few more...

 

[Ryland]

Oh well...my 750mah AAA's didn't cut it. I have a feeling its something with the mp3 player that I have, it just doesn't like rechargeables but loves alkaline..weird.

 

[lebe0024]

I need a AA charger and batteries for my kodak digital camera (which takes AA). What would you guys recommend? Not these 1600's right? Also, I can't go to sams or cosco.

Thanks.

 

[smartt]

Good deal. The rest is more than I wanted to know about batteries.

 

[misterj]

"powerizer" eh? what is the typical lifespan of these or thomas distributing?

i've used ebay crap that didnt work at all, to ones that have lasted about a year or so. it seems name brands like kodak, or whatever come with name brands, last about 1-3 years.

i liked how my dad's makita power tools had NiCad, and held good charges for 10+ years. i was excited about nimh a while ago, but have somewhat lost faith in them. lithium would be nice..

I'm not here to defend Powerizer, but the Battery Shootout competition seems to rate Powerizers much higher than Lenmars. For example, the Powerizer 2000 ranked 9th on the list, while the Lenmar 2000 ranked 22nd on the list (even lower than many 1800 mAh batteries).

You referred to the Battery Shootout as "infamous", implying that perhaps the results are questionable - I have no idea.

good shootout, but i dont see any mention of the number of cycles or total lifespan? or perhaps im misinterpreting something?

so should i get a the lower mAh if i want longer life? i don't see why i would need more than the minimum amount of current for the device i'm using. i just want it to deliver the same number of shots as alkaline, last at least a month between charges if not in use, and have a lifespan of 2-3 years. is that too much to ask?

btw i have a canon that uses a NB-5H nimh pack, or 2CR5 (one-time lithium i think), and 50+$ for the canon brand is just too much. these new ebay ones with "panasonic" cells are working but i think they are starting to die after only a few weeks. i've seen replacements from lenmar etc. and they cost 20-30$ but i dont know who to trust. *sigh*

like dman said above, alkaline bats have a higher voltage than NiMH bats (which is probably why rechargable NiMH aren't as good for things like flashlights, they don't supply as much power, hence not as bright). Perhaps your mp3 player doesn't do as well because of the lower voltage of NiMHs?

Another factor I don't think I've seen mentioned in this thread is 'conditioning' (completely discharging and then fully charging bats). Although NiMH bats are supposed to have no memory, after browsing the readers forum link on the great battery shootout site it appears that many users seem to get better results after conditioning their NiMHs. People with a charger that has that capacity might look into it a bit further.
