DL2032 batteries are not expensive. DL2032[URL] Geforce 9800 GT is PCI-E 1.1 card and does not use 128b/130b line code or PCI-E 2.1 or 3.0 bus speed and does not have certificate in bios.  This card will have power and bus speed issues and driver issues due to these problems.  Fitting Into the slot does not mean working.  Nvidia 9800 GT 512MB Graphics Card is not a good fit for ANY modern software. 2GIG 5450 however will run Minecraft and WOW and other basic games at 1280 x 720. This issue with bus speed 2.5 GTS vs 5 GTS vs 8 GTS and line code 8b/10b vs 128b/130b is well known back to 2009 and the release of windows 7 [URL] UEFI Class 2.3.1 is windows  8 2011 &  windows 10 2015 A card at least as good that DOES WORK would be VisionTek Radeon 5450 2GB DDR3 900861 [URL]  
I've thrown a bunch of parts together for a dirt cheap pc build, namely a Dell Optiplex 990 motherboard Intel i5-2400 Geforce 9800 GT   I've managed to boot into windows 7, install drivers etc, onboard graphics work fine. I want to try for dedicated graphics, the Geforce 9800 GT. I plug it in, seat it correctly, fan spin, NO OUTPUT. 9800 GT has s-video and DVI, and I only have a DVI to HDMI adapter. I've tested the DVI adapter on the 9800 with a different motherboard, worked perfectly. I've tested the adapter on a GTX 1050, different motherboard, it works. I've tested the GTX 1050 with the Optiplex 990 motherboard, it works with HDMI and Display Port output. I put the DVI adapter into the 1050 and there's no output whatsoever, identical to the 9800. Both cards are totally functional, have adequate power. Neither of the two produce DVI video output while plugged into the optiplex board, I've tried every pcie slot. One difference between the two cards I haven't been able to reproduce might be that, windows detects the 1050 as "generic vga adapter" in device manager, and the onboard video completely disables when the 1050 is plugged in, only letting me use the 1050's hdmi or display port. This, while the 9800 shows no trace of detection in driver software, device manager, or elsewhere. I can only get output from onboard graphics with the 9800 plugged in. I imagine that if the 1050 had DVI output only, I would also get no detection of any kind, just off hunch. Installing drivers for the 1050 might produce DVI output, and is possible. But focusing on the 9800, I am unable to do this, since it isn't recognized on the hardware level. My optiplex 990 motherboard running a fresh copy of windows 7 does not recognize my Geforce 9800 GT whatsoever, which utilizes DVI as its only HD video output. It recognizes a GTX 1050, but with similar exclusion of DVI. This represents an issue with the motherboard in my mind, not sure of what variety. I'm not sure why this is happening. Is there something that disables DVI output? Both cards are getting power, work fine in other rigs, but can't produce DVI output when plugged into the dell motherboard. Geforce 9800 GT only has DVI for HD output, I want to use my 9800 GT on this motherboard, but can't for reasons stated above.
Optiplex 990 motherboard, graphics card not found in device manager, zero DVI
