    I have some questions about the NIMH-battery pack.

    On my old Gpsmap62s, and my new 64s... i have used "normal" NIMH-batteries.. (and somtimes alkaline)
    I have not used the usb-cable that followd the gps but another one.
    And i have used an extranal charger for the batteries when theay are empty.

    I have the last few times used the cable that followd the unit, and it seems like it charge when pluged in PC.

    So to the question, du to some problem, i think that i will try the garmin-battery pack... and I hope that will help (if there is som "more" to the batteries than the NIMH that i use)

    Will it worn out the batteries if I plug it in (to transfere trips... and watch the map.. SD-card.... Basecamp).... and andout severel times a week.. so it charges a little bit then an little bit now? ... or should i remove the batrteries when i plug it in when the batteries are not out and wiat til they need charging?

    I would not recomnend the Garmin NiMH battery pack in this case, because you will not get 'more' than other NiMH batteries that can be purchased much cheaper, this pack holds 2 x 2000mAh NiMH battries in a plastic holder, the holder allows charging via USB while they are in the GPS, this is it's only advantage over 2 x AA NiMH batteries that can go up to 2800mAh and last much longer

    It is also possible to charge 2 x AA NiMH batteries in the GPS by inserting something into the battery compartment to activate the 'charge' switch

    Garmin say you should only charge Garmin battery packs in Garmin GPSs, however I can't see how either the batteries or GPS could be damaged as long as the alternative batteries meet a similar specification eg :-

    1) NiMH technology only (not zink, alcaline, Ni-Cad, Lithium etc.)
    2) at least 2000mAh (a larger value is o.k. a smaller one is not)
    3) Any make of battery that meets 1) and 2) above should be o.k.

    Although I reguard using the above batteries for charging as VERY low risk, I will take no resposability for any damage that does occur

    Your GPSMap64 needs to know what sort of battery is installed for correct operation, goto :- Setup >> System >> AA Battery type, Note :- the Battery type options may be limited if the 'charge switch' has been activated

    I have tried both pre-charged and std NIMH settings.

    and by the way, when i said plug in, I ment PC.

    I used a std USB cabel before (since the garmin was to long)...
    Now I use the Garmin-cable, and the last time (wich was the first time)... it seems like the batteries got more "juice" when i pluged it out agin. And what i was trying to say.... is it bad for the batteries to be charged a little bit then and a little bit then.

    I can't find any Info. on how long charging takes, but as the power is supplied via USB it can't be a fast charger, my guess is it will take at least 10 hours to charge (maybe twice as long with 2800mAh batteries), slower chargers are more tollerant of start-stop-start-stop charging and over charging, so I don't think 'little bit' charging will be bad. Garmin will have designed the charging circuitry to allow the battery to remain in place during intermittant USB connection so this won't be a problem
