Do i need to get the lithium battery or does it come with it. it is showing no rechargeable battery in the specs/what's in the box?

Yes it does come with a battery and a charger in a nice hard plastic case. Thank you

i want make sure if this product works on r134a and r1234

Compact and rugged, the DR82 Infrared Refrigerant Leak Detector helps you quickly find leaks in the field. The 10-year infrared (IR) sensor detects all HFCs, HCFCs, CFCs, HFOs and blends. warn Inhalation of high concentrations of refrigerant vapor can prevent oxygen from reaching the brain, resulting in injury or death. Do not use this unit in the presence of flammable gases or with A3 refrigerants such as R-290, propane or R-600, isobutane. Do not block the exhaust or the device or it will not work properly

This are good for 410 and mo-99 Freon?

It works great on R410A but I have not used it on a system with MO99.

Where do i find replacement filters?

I have also tested my vehicle charge port for R134a and this Fieldpiece detector did not disappoint. 😉

Very accurate and easy to use. Great budget leak detector.

Amazing leak detector. On the max sensitivity it doesn't have the false alarms I thought it, but using it can find eve tiny leaks, and then dialing it down I've been able to pinpoint every leak I found without even using bubbles. This is the best leak detector I've used so far under $500.

Very nice tool

I bought this as a backup since my stratus needs to be sent in for repair. This product works great. No regrets buying it. I've already found a small leak in an EVAP coil. Very nice product.
