Battery Tester recommendations?

[Mike Johnson]

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!!

When permanently on float, knowing the state of charge will tell you that the charger is working, but not whether the battery is any good. You might have a life-expired 7Ah block that is down to a usable capacity of only 1Ah, but that 1Ah is fully charged and will read good. The capacity tester uses Peukert's exponent and/or other methods to calculate from a quick discharge what will happen when current is drawn over a period of time.

I think I had a pint of that at our local real ale pub.

I used to drink a similar Pint when I was young . It was called Newcastle Brown Ale. It was the quantity not the quality that caused the reaction though.

Nothing fancy, just general abuse and wear & tear over the years.
A warning to all - look after your back! If you get a chance to go on a Moving & Handling/Lifting course it's worth doing, even for an update as techniques develop over time and the way it was done 20, 30, 60 years ago may

I could not agree more. I slipped a disc when I was very young, bending over to pull an arrow out of the ground. It has plagued me all my life.

Quite an acidic, citrusy flavour that has. I like citrus ales but less strong, Ghost Ship is good. I don't like the stuff we keep on tap in the workshop, Old Suds I think it's called.

The other way to test batteries is the spanner test!

Remove battery and splash a 13mm spanner across the terminals - if you don't get any or much of a spark the battery is clucked. Please don't try this in areas with explosive/flammable gases or liquids.

Kept me entertained this thread. I take it no one has one for sale?

 

[Mike Johnson]

In my younger days I used to test batteries with my tongue, kept me going all day. ?

ACT tend to be the go-to for most FD&A contractors I've found. If you're doing FD&A as part of an FD&A company (and not as a 1 man band job), generally these are supplied by the employer.
