guys, I just want to know what your thoughts are about Panasonic NiCads,

I have had Panasonic NiCads back a few years and their lifetime only lasted 60%-65% as long as Sanyo's do for me,, I just want to know what you guys think,

I like NiCads in my smaller planes and when I ordered new Sanyo's they sent me Panasonic's,

now if some one says that the Panasonic's are made by Sanyo, well OK, but I will have to think that because Sanyo is the Parent Company and Panasonic's are Out-Sourced> the Panasonic's are not up to the quality of the Sanyos,,

or maybe I just had bad luck with the Panasonic's ???

what are your thoughts about Panasonic NiCads ?

thanks guys

Jim

Any NiCd's these days are going to be suspect because they are for the most part no longer even made. If you are going to be using Ni based chemistry, you're pretty much going to have to migrate to NiMH if you want fresh cells.

Fourstroker came comment with more accuracy than I, but I suspect you're being substituted Panasonic for Sanyo because the dealer can no longer source the latter. If you learn how to read the date coding, you can see how old some of the NiCd cells are that are being sold.

Panasonic bought Sanyo (batteries part) in 2009. Any cell marked Sanyo is therefore 7 years old. According to Red Scholefield, the AMA mag. battery guy, the shelf life of NiCD is 7 years. This was his career. It's even worse than Ben suggested. The date code on the shrink wrap can be anything they want. The surplus NiCD cells are stored bare naked. They are dated somewhere in the supply chain before retail. Drill packs don't have shrink wrap do they ?

Get a LiFe charger and some LiFe or A123 packs.

A few years ago I bought some NiCD cells dated like new. They were crap. Selling junk surplus batteries to RC'ers has been going on for 50 years that I personally can attest to. I switched to the big A123.

yes I can read date codes, but I can't speak french, and I can't see the code without cutting up the shrink rap, and that would void the warranty,,

well, I will ether send it back or keep it LOL

thank you, Sir (s) !!

There are people (mostly plane guys) who refuse to buy anything but NiCD. There are reputable places that will attempt to source and sell to them. But there are other places that sell junk surplus cells without shame. NoBS is a good guy. He would rather sell you A123 and says so ! Batteries America/EHYohst/Mr.NiCD will sell you 10 year old cells that are dead on arrival. I know by experience.

NiCD and even NiMH are obsolete technologies. A123 is not as energy dense as other Lithium cells but is the most RELIABLE cell that I have used. They may also fade away.

It is unfortunate that our RC Hobby market is where all technologies end - and cells are dumped.

The Panasonic 18650 3200 Lion cells are current tech since they are used for vaping ! They should be fresh. They make a good HV RX pack and are used in the JR 28X and XG14E TX's.

http://www.batteriesamerica.com/new_page_3.htm Currently there are three companies that sell r/c battery packs. I listed this link because this is the one I use. All my fixed and rotary wing models use NICDs.

I think NiCad are the most durable and safest. NiMh are ok, big power when you first by them but after a short bit, power declines a bit plus when they die off quick at the end of there charge. NiCads aren't as big in energy as NiMh when new but the last longer over the years.

Should buy a cycler to keep an eye on any battery pack.

NiCad and NiMh are good for TX and RX but I don't think they should be used to power engines, not sure if they can be.

I have been cycling NiCads since the mid 80s

I haven't used a NiCAD in years. Ive switched over to all A123 RX packs and the only nickel batteries I use are the low discharge NiMH pack in my transmitter.

I once tried Eneloop NiMH for RX applications... didn't like them. The low self discharge ability comes at the expense of not tolerating high rate discharge or fast charging well. Also note that apparently even Eneloop has been renamed now since the Sanyo/Panasonic ownership change (according to the guys at Radical). They work great as rechargeable AA batteries for the TV clicker however

If you really want NiCADs I would call up and talk to the guys at SR Batteries or owner of Radical RC. Both dealers have very long history of dealing with Ni batteries and the SR guys especially are experts since they dont deal with anything but Ni batteries and they are a full time business who also does work for gov/UAV industries.

If neither one of those outfits has what you want ('Id be surprised) you can also try Hangtimes Hobbies (NOBS Batteries).

Im not sure why flycatch thinks there are only 3 companies that sell RC batteries... there are a lot more than that, probably dozens if you include the shops that only deal with lithium and the big distributors (Hobbico, Horizon, etc).

I'd avoid them at all costs. Too many superior options available today with LiFe, especially genuine A123.

Hangtimes has/had some low impedance NiMh which may be an option if you really don't want to go LiFe/LiPo.

I stopped using NiCd 10+ years ago and never looked back.

The last time I ordered a battery pack from Radical RC, he apparently did not own a spot welder.

HK claims to have (I have not seen or tested any) GENUINE A123 cells with solder tabs for a mere $9. Make you own packs.

I am really ticked off that W.S. Deans does not make the 8 pin connectors anymore so I could use them for balance leads.
