Battery Tester recommendations?

Good luck Timbo, but how did you do it, nothing simple I hope, some amazing story, if not make one up.

How accurate does it have to be and what does it measure, there are some very cheap ones on the market that seem to work, but as Tel said just replace them if you think they have been in a while, then on your report just say "Fire Alarm battery replaced" looks better than "Fire Alarm battery tested"

It’s basically got to measure the Ah in the battery and Voltage. They get replaced between 3-5 years anyway. It’s just for servicing which is every 6 months.

The bar graph show 100% does not take much effort the estimate the capacity left. Amazon.co.uk - https://www.amazon.co.uk/Digital-Battery-Tester-Universal-Voltage/dp/B08B83NZM6/ref=sr_1_11?

Its used for testing 12v batteries. You can also test car batteries with the ACT ones I think. They are quite expensive and being an Adult Apprentice it’s a lot to outlay.

£9.99 is a lot to outlay?

Obvoiusly there is a difference between a voltage tester that just shows the state of charge (regardless of the battery capacity) and a capacity tester that shows the battery performance and hence useful life. The capacity testers take a small amount of charge out and use a formula to estimate how much charge would be available if it were completely discharged. Obviously it is quick and convenient but not as accurate or reliable as a full discharge test.

Not a pink case Tel. A pink tester. Must be a special edition ?

I once got arrested by a female Police Sgt who actually had genuine police issue handcuffs, in pink powder-coat!

@Lucien Nunes Quite so, but think it's a bit of overkill to test a Fire Alarm Battery, just a test between inspections giving an idea of state of charge I would of thought was enough.

Was this in the privacy of your own home or the privacy of a room in West End of London?

It was in an actual Police custody suite, sadly! And...... the reason was...... I'd already been wrongfully arrested after a false allegation by my pyscho ex and taken in for questioning (later released without charge) but in the search prior to going into the holding cell I had my CK electricians lock-knife in my pocket and so got re-arrested on suspicion of carrying a weapon!!
