    I’m having trouble charging this battery and can’t figure out why. I bought the battery standalone, it had a full charge on it and ran my livescope for one day, worked great!

    Went to charge it and it won’t charge. I’ve tried my Marcum lithium shuttle charger(1.5 amps), and a norsk lithium battery charger I bought today (2 amps).

    I asked around and someone told me you have to have at least a 3 amp charger for it to charge. Is that true? My lithium charger I bought is only 2a, so I’m hoping it’s just a simple fix like that. Is that a thing though? My assumption was that it would just take longer to charge…

    Did you buy it new? Mine came with the charger and it says to only use the one that comes with it….I’ve never really believed that. I use the charger for the king to charge my other marcum brute batteries with no issues.

    Here are the charger specs in the pic.
