Hello, I have a small question: my NAV4 Tomtom battery seems "a little" dead. I keep it 2-3 hours on a in-house charger and after powering it up it keeps 3 seconds and says battery empty so I think its dead. I has 5 years though, so I its past its life cycle. The question I have is about the compatibility of the batteries. I opened up mine and has a VF6F 920mAh 3.7V battery. On ebay I found only VF6S or VF6D batteries. Will they work if they have same connector and voltage but different capacity?
