    The model 430 allows for USB charging of the receiver batteries.

    In the settings there are 3 choices for battery type.
    The rechargeable choice listed is NiMH

    I have many sets of NiCad batteries for my game calls. I swap out battery cartridges on my electric collar after every set because of temperature.

    They recharge fine for me.
    I use them in Garmin handheld gps’ as well.

    Yet, they do not seem to properly recharge, if I put them into the Astro.

    I can charge them at home, they are 2300 mA batteries, but I cannot make an entire weekend with one set of batteries in the receiver. Yet, if I plug in standard AA batteries, it will run several days before it needs batteries.

    And the NiCad batteries don’t seem to charge properly in the 430 via USB cable.

    Anybody have any experience or correspondence with Garmin related to this? I don’t really want to spend another 25 bucks on a single set of batteries when I have 30 Nicd’s sitting here.

    If your not using the Garmin pack ,there is a button on the inside of the unit that the Garmin pack depresses so they will charge . If you look at the pic I put a thin piece of plastic in to depress the button .been running them like that for years ,no problems

    You use NiCd or NiMH?

    Thanks for the tip.
    I'll do it when I get home.

    I'll try that trick on my NiCd's and report back.
    NiCd's are very tolerant of overcharging.

    Yes, if you take a thin piece of plastic, like from a plastic cookie box, and put it in before the batteries, it will depress the button and you can use off the shelf rechargeables. I've been doing it this way for years.

    Wow! Thanks so much. I too had given up on rechargeable batteries in my Astro 420. Will McGyver my Astro with some plastic this evening.

    Isn't it funny how Unless you didn't want to buy a $30 pair of generic batteries from Garmin, no one would ever know about that button.

    I've never seen it discuss ed before

    I thought it was to stabilize the batteries from bouncing around hunting so it didn't turn off in use

    I couldn’t get a thin piece of plastic to work or stay inside my Astro 430. The batteries kept popping out. I opted for a piece of plastic twice as large as the button and HVAC tape to keep the small plastic piece that holds the tab down in right place, keeping the button pressed. Wow. I get a “charging” icon on my GPS screen.
