Hello All,

I have received a Battery pack with a Nitro Car but without charger. (Pic No-1)
Brand : VB Power
Power Rating : 5*1.2v 1500mAh
In battery pack its mention : Standard Charge 14Hr  at 150mAh


My Query is Can I charge it with my another charger, by modification in its charging lid. (Pic-2)
Brand: Unknown
Power Rating : Output DC 7.2v 250mA

It came with a cheap toy car, and I used to charge 7.2v 700mAh battry (NI-CD)

Another twist in story,

That charger is giving 10.6v when I checked on Multimeter

Can anyone suggest me..

the charger output will be the higher then the battery power,,, but when you will attach with battery and starting charge then it will be the same as battery power due to the charging load on the charger.

hi thanks kapil

yes I have noticed same but now one more question.

charger come to charge battry  NI-CD

but battry seems N-MH

will it charge and what is calculation for mah between battery and charger

mah means current.... it must be same

ok but
charger is providing 250 mah
and battery is 1500 mah

this charger come with battery 7.2v 700mah

then it will take more time to charge

You are going about this the wrong way! Is it a 3 cell pack or 5-cell pack? (I can see 3 cells in pic 1)

If it is 3 cell, then you need 3 x 1.2 = 3.6V charger
If it is 5 cell, then you need 5 x 1.2 = 6 V charger

Charging with a voltage which is much more than the battery voltage can seriously damage the battery! 10.6 V is certainly bad for a 3 or 5 cell pack! Even 7.2 V...

"Standard Charge 14Hr  at 150mAh"

And it is recommended to charge at 150 mA, not 250 mA.
If you do charge at 250 mAh, it will take less time but might shorten the life of the battery...

hi swapnil thanks for ur valuable feedback

it is 5 cell, as discussed above when i m connecting charging its showing 6.5v

and what about  N-MH & NI-CD battry difference.

NiMH should have a max voltage of 1.2 V per cell. Overcharging may shorten their life.

yes swapnil its 1.2v but can I charge Ni-HM battery with Ni-CD charger ??

You can certainly use a NiCd charger if it is of suitable voltage. That is, you can use a 6-cell (7.2V) NiCd charger for a 6-cell NiMh pack but not for a 5-cell pack.

Try to find a 6V-150mA charger/ adapter. They're not costly and you won't have to risk damaging your cell pack.

do u hav a charger for lipos like the turnigy accucel 6 or something like that. if so with the leads that have the diff connectors u can modify one to charge this battery pack it'll take about 5-7 mts to charge.

As per my understanding Battery pack to be charged with "Trickle Charge"

I was just suggesting a cheap method. Using an adapter does require monitoring of the battery to protect it from overcharging.
Trickle chargers are certainly the way to go.
