I need a replacement battery for my JR9503 radio.

I have searched, and it seems to be a hard battery to find.

It has a 9.6v Ni-HD battery pack which they recommend.

What replacement battery should I use as JR doesn't make their battery anymore?

Thanks, Dennis

I have a battery from NoBS batteries in my 9303. Had it 3 years or so. Still an excellent battery.

I search for the battery using your wording. Several hits came up.

I wonder if this battery will work in the JR?

I could change the plug on this battery.

Your Thoughts?

I don't want to burn up my JR, just being careful before doing something.

This one looks like it has the correct JR plug

Description actually states it's for a JR!

Expensive, ? ? ? ?

I burned one radio up before, don't won't a second one.

This looks like a candidate, just have to change the plug.

Price is decent.

I am told it's best to use a Ni-MH pack! Opinions?

By the way, I have found several replacements, but $50 to $60 plus is a little more than what I want to pay.

BL that battery will not fit a JR radio, the cells are in the wrong orientation.

He is looking for a pack that has 4 cells in a square configuration and then 4 more end to end.

I run a LiPo in my JR radios. If you search you will get mixed reviews but it works and will not endanger your radio.

I have also run the Enlopes but you have to be careful charging them because you can cook them. Hangtime has great information regarding this. It has a lot of information relating to batterys.

I use the life battery from amainhobby.com because it's 6.6v and you still can use the wall charger.

I use a Turnigy 1C 2650mah 11.1v Transmitter pack lipo in mine. Has the JR plug already on it. Been using it for over 3 years now and still going strong.
I tried a 11.1v Lipo in my JR 9303 radio. I blew the fuse and burned the board in the transmitter.

Horizon told me to only use a 9.6v NiMH in the transmitter.

It's a great price on the battery, but I don't want to burn my radio again. I have found a few, I guess I will decide which one will be the best value.

DemetriusUSN has a great suggestion, I don't think I have ever used a LiFe battery, and have no clue how it compares to a NiMH.

Anyway, it's time to make a decision. There are some out there for >$20.00 and up to and above $60.00.

Thanks, Dennis

PS: This battery listed on Ebay might be the one considering the mAh's. Listed above.

I like the life because you use the wall charger that came with the radio. If you use a lipo, you have to take it out and charge,there's nothing wrong with that but the life route is easier.

New scenario, or question ? ? ?

I am also looking a NiMH AA batteries which are 1.2v each with some having a 2,000 mAh capacity.

My Devo Transmitter has a pack you put AA batteries in it, series.

If you take 8 NiMH AA batteries packed in "series", you have 9.6v, correct?

If each AA has 2000 mAh's, when hooked up in series, what total mAh's do you have?

I know parallel packs you would have 16000 mAh's.

Is this the same for Series Packs? or ???

I have been looking all over for an answer to this question. I don't see a problem if you have 18000 mAh's, I guess the batteries would never die. The reason NiMH batteries are recommended, they don't have a memory like Lipo's. This "definitely" is the cheapest way to go! Plus you can order a JR radio connector.

Answer found: NiMH battery in the standard “AA” size has about 2000 to 3000 mAh (or 2 to 3 Ah). With a cell voltage of 1.2 V to 1.5V, this corresponds to 2 to 4 Wh per cell. When multiple cells are used in series, as with the use of a battery holder or most pre-made battery packs, the voltage goes up but the capacity in amp-hours stays the same: an 8-cell NiMH pack made of AA cells will have a 9.6 V nominal voltage and a 2500 mAh capacity.

I am getting a real education on batteries lately.

I even found a company that will "CUSTOM" make a Lipo battery for my TRex's! I will post the price when I get it. I requested a price for a 22.2v 18,000 mAh, 35C battery pack! LOL, it's worth looking into.
