will this battery replace a wa3575 battery?

Yes it will. I have both this battery pair, and some WA2575's They both are 20Volt, while the worx is 2Ah, these are 3.0Ah capacity. Charge in a Worx charger, I have three different Worx chargers and they all will charge these and other Worx battery

Will these batteries work with a wg170 weed eater and a wa 3881 charger

Look in your user manual. If the voltage is right then they will. I use them in a lot of different WORX tools. I have a 3881 charger and several other number chargers and they will charge all of these batteries.

My old battery is a 18v lithium, wa3512.1 and charger wa3840, what battery should i order

20-Volt, and you have a choice of 2.0-Ah, 2.5-Ah, 3.0-Ah, 4.0-Ah. Just look around. The 20-V battery is only 20-V when fully charged and has not been used yet, they are really rated at 18-V when in use.

Where can I buy a replacement Worx 40 volt battery and charger

I found some on Amazon, try looking there. Also WORX sells them. Ebay has them listed also.
