Gooday all.  
I’m new to all this electronic stuff but I’m starting out by replacing a battery in my Hema GPS.  
Can anyone tell me where I could find a PT103759 battery to suit ?

Hi Lance  
If Core don’t have a suitable replacement Battery World might be a good place to start.  
Cheers Bob

This one is quite popular for the Hema HN7:

Hey Lance,

As Graham mentioned above the 2000mAh one we stock is a match for the HN7, if you have a different GPS model, measure up the size of the battery cavity and let us know the dimensions. We have a few options and we can try and figure out what’s going to fit best!

Hope this helps!
