rechargeable battery question

[thecavemankevin]

I'm thinking about buying this lot off ebay of 2500mah NiMH AA's for use in kids toys. I'm sick and tired of buying D's and AA's for the kids toys and this seems like a decent solution. It comes with AA to D battery adapters so that will help with the newborn's swing (eats batteries almost as much as she eats).

I never did understand why manufacturers dont make devices like this with a wall plug option. I mean come on, big swing. I'm not going to be moving it all over the house, why not be allowed to plug it in?

so you guys who know more about batteries than i, is this worth it if its just powering basic devices around the house (remotes, kids toys etc...)?

NiMH isn't really designed for all devices. Sure they will work, but for some things Nicad are still better.

The only thing to remember about NiMH batteries is that they are very sesitive to over charging and heat.

^ dang beat me to it ...

I purchased rechargeables a while ago ... i have build quite an army of rechargeables ... the trick is getting in the habit of keepig the extra set charged and ready to go ...

But definately worth it ... but i've found that going to the electronics store almost always comes out to about the same after adding shipping ... for batteries that is...

oh and for the swing ... fisher price makes one that plugs in ... it's the onlyone on the market ... it has worked great ...

i think he meant it was a fisherprice swing with plug. and i know, they started offering it about a year after we bought our swing for our oldest daughter now 2 1/2. That is the same swing we are currently using.


thanx guys

Yeah the one with the plug ... awesome stuff ...

i wish i'd never got rid of the one my son used with the manual hand crank ... he used that think till he started to crawl out of it ....

the electric one sucks ... it can barely swing my 15-18lb daughter ... it's wimpy ... but grandma purchased it ... what ya gonna do...

just how sensitive to heat? and they don't release more heat than NiCd during rapid discharge, do they?

to answer the original question, one other thing you have to consider is (IIRC) NiCd and NiMH cells are 1.2 volts, while normal alkaline batteries are 1.5 volts. they are still great for most applications, though.

Naa too much effort ... i thought about putting on of my RC car motors in it ... but they are twice the size of what is in there and won't fit ...

But i did laugh ... and i wouldn't use a wimpy electronis weedwacker ... oh no gas powered baby with a throttle that the baby could play with :D :cheers:

I've opted to just let her roll around on the floor ... but that just doesn't do the trick at bedtime ... the swing has some king of elf/gnome magic that puts her to sleep when in that thing ... i think the magic is wearing off ...

i think there is some residual alcohol from last night in my system ... i've edited 3 times and each time i find something else wrong or mispelled in the post ... igive up
