charging AAA s

[ill_race_ya]

just wondering if you can charge AAA s with a normal 1:10 scale battery charger? and if so, at what charge rate(amps) should i charge at. i just went and spent like $30 on this charger for the AAA s and then thought to myself hmm i wonder if i can charge them with my other charger. should of thought of that b4. god i m stupid:dead:

[merc-blue]

yeh you can.. depends on the AH rating of the batterys i charge my .8 AH at 1.5-2 amps

[ill_race_ya]

wat u mean by AH rating. the batteries are 700mAH is that wat u mean?

[merc-blue]

yeh thats it.. milli (m) is the same as x10^-3.. so thats the same as .7 you can charge them on 1.5 amps

[ill_race_ya]

thanx, u smart

[merc-blue]

lol no maybe u are dumb.. JK.. what 1:10 u have (im guessing that what u use a delta peak for)

[z-beam]

if you’ve bought a dedicated charger for aa/aaa batts then use it!

what type of batteries are they?

[merc-blue]

z-beam a delta peak is a much better charger than a ni-cad/nimh charger (if its a set for a time period then com back) unless its a delta peak which most arent

anyone got that 45 min AAA `charger for $17.90 from dinball rc mart? If so, is it any good?

[merc-blue]

17.90 USD + postage.. i would get a 2nd hand delta peak off ebay .. can do them in 15 mins (with a ice pack)

[icebreaka]

hmms.. how do u know when the batteries are charged? and in what way do u use the ice pack?

[merc-blue]

a delta peak cheack the output of the batterys and stops when there fully charged and then swaps to a trickle charge (to keep them charged fully untill you check) you can vary the input to your cells to vary charging times.. the ice pack its too keep the cells cool (because of high input) all the 45 min charger will be is a standard charger .. with a higher current (my cheapo charger does them in 5 hours with its output this thing wil have a higher output to charge them faster.. pretty simple the 45 mins thing is abit of a gimick i think.. you basically plug them in and do some math to work out a suggested charge time but never fully charged becasue you dont know about residual charge the worked charge time is always abit undercharged etc etc etc .. if you dont get that tell me and i will re phrase it all

[icebreaka]

hehe well i dont really get it .. lols

but about delta chargers, they wont overcharge the AAA batts but since you supply more current they’ll heat up so therefore u use the icepack to keep em cool? and it’ll only take 15 mins that way?

How much current does the delta peak charger supply versus a standard charger?

[merc-blue]

well a standard charger supplys a set current a delta peak can supply a varity of different currents set by a knob on the front mine does up to 10 amps (which will blow most standard batteys only high capacity batterys cna be cahrged).. u can do low current for battery condidtioning and high current for quick charging between races… a delta peack can have the batterys set in them “charging for a month” and not over charge try it with a standard charger (DSE sorta thing)and you will have a fire.. yeh 15 mins on a high curent

[icebreaka]

hmms..

would this charger work for Nimh batts lols even tho it says Nicd? hehe.. and is this the type of charger im looking for?

I just hook it up to a AAA 4-cell holder and it’ll do its job?

[merc-blue]

most chargers do both nicd/nimh (pretty much the same chargin sequence)

[jamiekulhanek]

This is how I charge my batteries.

Get a large cup of icy water, and a plastic polythene bag.

Put the batteries in the bag, and throw in the cup, make sure that the batteries don’t get wet.

This way you can charge the cells at 2+A without them overheating to self destruction.

The other alternative is Rayovac IC3’s

These are self delta peak charging cells that fully charge in 15 minutes…..i am yet to get any but i hear they are great.

[merc-blue]

lol jamie i do mine at 4.5 amps and just sit forzen peas ontop and they dont heat up THAT much

[icebreaka]

sorry when i said this charger.. i meant this:

http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&category=1200&item=5910375796&rd=1&ssPageName=WDVW

can it do nimh? and is this the sort of charger im after?

thanks

[merc-blue]

yeh that will do it.. and yeh hook that up to a 4 AAA pack and you will do it you will beable to charge them like jamie said much faster then the rcmarts ones.. just a note (these all have 12V inputs) so you can use either a car battery/gel cell to power it or a 12v power supply with a current rating for a few amps

[kitsune]

From memory Ni-Cad batteries have a sharper voltage drop once they peak than Ni-MH batteries … so Ni-Cad Chargers may not notice that a NiMH battery has peaked because they arn’t looking for such a small voltage drop – consequently Ni-Cad chargers may overcharge (ruin) Ni-MH batteries.

[icebreaka]

oh ok thnx i’ll look at getin one from america on ebay

[merc-blue]

yeh icebreaka look for a nicd/nimh delta peak
