They're different!
Ok and ThankYou for the confirmation.
WB have 3 different types of Panasonic 3400 mAh which is best as I might as well buy from them with the discount applied, only makes sense.
1./ WallBuys.com is for sale | HugeDomains
Go with 3, they are the best protected batteries you can buy and no doubt the ones I’ll be ordering with my TK75
Do any coupon codes work with batteries?
Yes the Coupon Code “WALLBUYSALLMAGIC” also discounts the batteries also and comes to $192:15
it is still cheaper than what i paid without the batteries 
Sooooo tempted…or keep waiting for the FFIV….choices…
WB’s FF4, with 11% coupon code, is currently $210. Doingboutdoor still has it for $208
11% off batteries as well?
He has some Keeppower cells on sale I think.
As for the Panasonic NCR-PD prices, email Bill your asking price.
