Anyone aware of a source of sealed lead-acid burglar alarm batteries at
sensible prices?

TIA

I've bought a number from CPC, but I didn't search far and wide
for cheaper ones (have seen them a lot more expensive elsewhere
though).

I got mine from a B&Q Warehouse.

If you want a one off, a special offer powerful torch which uses an SLA
can often be cheaper than any replacement. Makes no sense, but these
things rarely do.

Yes. It costs less to buy one of those car starters with built
in 24Ah battery, tyre compressor or 240V inverter, and charger,
than it does to buy a 24Ah SLA battery alone.

I have one of those bought from Lidl for under 20 quid and didn't expect
much of it, but some two years on and having started quite a few cars as
well as being used for blowing up tyres and as a convenient source of high
current 12 volt DC for testing some car electrics, it's still fine, and
has proved an invaluable device. Perhaps there isn't the same spread of
quality between SLA batteries as with Ni-Cad, etc, or it could be the
chargers are rather better designed.

I bought one of these from Lidl and topped up charged for about 6 months
then had a real life need to use it!

I clipped it on to the battery and ..... Click.... went the starter
solenoid and that's all !
The battery meter was showing full charge volts as it had always done, but
was unable to
turn the engine at all - and this was a motorcycle engine !
I got the leads out and jumped it from the car.... still haven't taken
apart to see what
the problem is, but I don't think its lead / contact resistance....

But be aware that those BFO lamps might be 6v rather than 12v that alarms
commonly use. Last SLA batteries I got for the UPS came from CPC,
previous set came from Bristol Batteries.

I've got a voucher for B&Q so I'll give the local branch a visit.
Failing that it'll be CPC.

Thanks for the help.

Beware, the batteries that come with those zillion candelpower torches
in the DIY sheds are utter rubbish.


Dunno how much candlepower, but my 55 watt Homebase special works ok.
Can't say it's had a hammering, though. But the battery seems to keep its
charge.

Could be. Leaving one plugged in permanently certainly killed
the battery in a couple of weeks.


Never a good idea if you're not sure about the charger. Applies to power
tools also.

A new battery was about 4 times the price of a replacement torch, which
made me suspicious.


Often the case. Who knows these days what things should cost? However, the
SLA battery in my el cheapo jump start pack has done well - and the
charger switches off when the battery is charged.

I'd be reluctant to put one in an alarm, that's for sure.


I suppose it depends on the alarm. Some panels are extremely competitive
in price so if including a battery the same might be said about it.

Was thinking the same - I'd won't something better quality backing up
the alarm than the ****e in those torches. Anyway, as mentioned, the
torches are mostly 6V.

A nice Yuasa or Genesis is want you want for reliable backup.

If you look further down the tread, it may have been the charger that
knackered the battery.

I did see that. Crap unregulated chargers don't help matters certainly.
But I was given one of these torches, its only _ever_ been charged on a
regulated 3-stage SLA charger (not the POS charger it came with), hasn't
been used much anyway, and still only gives about 8-9 minutes before the
first cell in the battery dies.
4Ah battery into 25W bulb (i.e. ~4A load) should give about 30 minutes.
(For those smart-arses about to say 4A from 4AH should last 60 minutes -
go look at some battery discharge curves).
