For a few pounds more than a battery tester I have a reliable multimeter
I needed a good battery tester, having experienced that the usual cheap ones were not very reliable. I decided that I may as well invest in a multimeter that could test batteries. I'm very pleased with this - exceptional quality for the price (YouTube reviews attest to build quality) - and it will test 1.5V / 9V batteries 'under load' to give an accurate remaining voltage reading. You have to use the supplied leads to 'touch' the battery +/-contacts so perhaps not as convenient as many specific battery testers, but this multimeter does have a built-in stand which means you have both hands free.

Perfect for all my jobs
This is the second multimeter I have purchased. I wanted to test an earthing sheet and the one purchased from Halfords wouldn’t test low enough. This one did the job as much more accurate and a much sturdier feeling device. It has since proved itself again with vehicle fuse checking saving me garage costs. Would thoroughly recommend.

Amazing Multimeter for the Price
Klein Tools MM325 Multimeter, Digital Manual-Ranging 600V AC/DC Voltage Tester: Love my new Klein multi-meter, very accurate readings, nice clear screen, 'normal' batteries, and the leads are good quality. I bought an off-brand hard fabric case for it to keep the leads in good nick. Lovely multi-meter, and just as good as the bigger more-expensive "F" brand units.
