These are nice HT batteries and well worth considering if you wish to avoid traveling with a drop-in charger or keep a spare battery in the go-box, glove box or center console. Cost is about $4 more at LGR.
I’ve had drop in chargers in my car trunks for years…not any longer! I plan to replace the stock batteries with this “C” model over time.
