What if any are the suggestions to buy a battery tester? In the last 2 weeks I’ve had to replace the battery in my p38 and reliant scimitar. Former was 6 months out of 4 year guarantee so had to pay for its replacement, latter was 2 years 2 months into a 5 yeAr guarantee and replaced foc. Halfords did a test and declared a dead cell unit looked like something the AA used to declare my future son in laws battery to be u/S a few months back. Have numerous multimeter s but not that determine a dead cell

I have got a professional tester similar to this one:

https://www.toolsource.com/battery-testers-c-24_528/otc-3184-professional-battery-charging-starting-system-analy-p-97887.html

However, mine is badged differently. I picked it up s/h on Ebay for about £35 from memory. Worth its weight in gold if you own a p38. It measures Cold Cranking Amps amongst other things.

You need get one to measure at least 1000 Amps, particularly if you have a diesel battery fitted,

Those with a big resistor or rheostat inside such as this: https://www.amazon.co.uk/GYS-TBP-100-Battery-batteries-x/dp/B001U1XNTS/ref=sr_1_31?s=automotive&ie=UTF8&qid=1546429163&sr=1-31&keywords=car+battery+tester get red hot very quick.
