Remington SP-94 Microscreen 3 Replacement Screen and Cutters for MicroScreen 3TCT Shavers

Can I buy a replacement battery for an ms3 1000 razor?

Are the screens easy to fit on?

Are these SP-94 TCT cutters made by Remington in their packaging or made by Aftermarket

I want replacements for my ms3 2700 titanium. it says the replacements are sp94 but i don't know what the tct stands for. can anyone help me?
