Why replacement batteries have 4 contacts..curious
I have been wondering about something so just going to see what you think.
The original HD100U battery (model BN-V428U) has 3 battery contacts but replacement batteries have 4 battery contacts. Wondering why? Is it because the batteries work in several models and not just the HD100U? |
