Suggested charge rate non-peak detecting 215mah or less, peak detecting 1075-4000mah. 4 amps is the max charge rate through hobby pins.

According to Great Planes, you may need a new battery cover to upgrade from the AA battery holder to this battery pack. Quote: "To use the NiMH battery FUTM1473, you will need to purchase charger FUTM1832. Then call Futaba Services at 217-398-8970 option 2 and they will send you a battery door- HSP82469. If you already have a charger and need a charge lead they can sell you part number- HSP29615. (requires soldering on the correct charger plugs)".

Side By Side, 9.6V FDK (formerly Sanyo) 8-AA 2500 NIMH cells, fits Multiplex radios. "Twicell" (formerly Eneloop) low self discharge type which comes partially charged and is the same product as prior Twicell (Eneloop) cells. Same size as 700 and 1100 NiCad pack above. Less weight than 1400 NiCads above. Good cell where fast charging is not a needed but extra capacity is desirable. High capacity TX Battery, if you are sick of your TX running down. Yes, it is the same size as your current AA pack. A "AA" is a "AA". This is what your computer TX should have included!

9.6V Weight 312g / 11 oz.

Individual Cell Internal Impedance 20.0mΩ

All AA size cells over 1700mah should not be fast charged ever! If you repeat this experiment, your on your own. I recommend only factory wall wart charging with units rated of 70mah or less for these type cells. Break in (first forming charge) on 50mah factory wall charger 700mah-19.6 hours,1100-30.8 hours,1650-46.2 hours, 2500-70 hours. For 70mah wall charger deduct 28% of time, for 100mah wall charger deduct 50% of time. Forming charge (initial charge) on peak detection chargers is not recommended and voids warranty. Any peak or fast charger use on this pack voids warranty. Don't bother calling trying to get a warranty for failing to follow instructions. I've heard all the stories. They all end like this, "My battery does not cycle well now." and "It worked ok for a while but now it runs down fast shortly after charging". If you put any AA cell over 1700mah capacity on your peak charger, it's bad. I've already made theses tests for you so you could avoid the pain. If you ruin one of these mega capacity TX packs, just order a new one and do better the second time.
