1.5 Volt Rechargeable batteries

[niceguy71]

I mentioned a long time ago that I had found some EBL 1.5 Volt Lithium Ion Rechargeable batteries on Amazon and it has greatly helped me with my old HandHeld CB tests as some of the old radios didn't take rechargeable batteries and I'm not going to keep buying Duracell or Energizer batteries just for testing old HandHeld Radios... (radios like the GE only allow 8 batteries and they need to be 1.5 volts. not 1.2 volts )

my NIMH rechargeable batteries are a trickle charge and take over 12 hours to charge..... the Lithium Ion can be recharged in just over an hour.

someone told me that Lithium Ion Batteries make a lot of RF Interference.... I think it was (PRCGUY or maybe Merlin ) and in all my testing I have not had any problems and they all transmit and receive just as clear as other radios with NIMH rechargeables.... they don't last as long but they work great, and last long enough.

well I just found out all my radios that have the weather channels, wouldn't work???? it didn't matter what brand radio..... if the Lithium Ion Rechargeables were in it.... nothing but static on all the weather channels.
so I took out the Lithium ion batteries and put in NIMH rechargeables and the weather channels came in crystal clear again.

just something to be aware of.

Does that set-up interfere with any other radios trying to receive WX?

Good question, I'll have to take a look

I hear you loud and clear on burning through alkaline batteries. I have some Coast Li-ion AA batteries and they generate noise as well. I posted my results in the thread below. Most of my rechargeable are Ni-MH. I also use lithium metal AA batteries for certain non-radio devices and need to test the Li-ion instead.

* I only noticed interference when in close proximity to a device using the Li-ion, or using them directly and the interference was only on certain bands.

If you have space in those radios, make up a series battery pack of regular Lithium Ion cells that produce the desired terminal voltage of the Alkaline string. A lithium Ion cell produces 3.7 to 4.2V at the terminal. An Alkaline AA tops off at 1.5-1.65 V so qty. 3 series Lithium Ion will give you equivalent of 8 AA in a nominal 12V radio pack.

Unfortunately, those Lithium batteries in the OP have regulator chips, limiting them to 1.5 V and making all the noise. It also removes the best point of a Lithium battery, the high discharge rate.

18650s or 21700s would make a good external pack if the HT has a power jack. Depending on the battery compartment layout, you might get 3x18650s inside one; 3x18350s would fit, but are getting harder to find.

Be very careful with Lithiums. They use a buck convertor to limit the voltage. If that goes south the batteries will fry your electronics. It's why I never use them anymore and just use NiMH batteries. My charger is a fast charger, but I know that's not good...

I would just load up on the NiMH's so you always have a fresh pair. And never leave the charger alone. I'm sure these aren't even UL listed. Mine isn't and it's an Energizer! Same applies for cheap Chinese radios and their craptacular chargers.
