Halfords Leisure Batteries

Dry cell torch batteries are better than AGM.

Interesting theory pappajohn
Wonder how many AAA Ducacel's I could stash in my van.
Indeed how many would I need to replace my 160ah AGM.
Lots of soldering I would have thought.

A VRLA battery (valve-regulated lead–acid battery), more commonly known as a sealed battery or maintenance free battery, is a type of lead-acid rechargeable battery. Due to their construction, they do not require ventilation, can be mounted in any orientation, and do not require constant maintenance.

Considering some leisure batteries are just relabelled car batteries at worst and slightly differing in construction (thicker lead plates) in best cases.....I think the same as the above will apply to leisure batteries.

The article then goes on to say
Likewise, do sealed lead acid batteries vent? In order to achieve a maintenance-free lead–acid battery, a sealed battery was developed in 1970s by adding a valve to control the venting of gases during the charging and discharging operation. The purpose of the valve is to act as a safety vent when gases build up during overcharge or discharge.

Regarding this, what happens if you don't vent a battery?

You have a major fire hazard or even an explosion in your boot, as while lead acid batteries are being "used" they release toxic and flammable gasses. Also the gasses could/will leak into the cabin .. if that doesn't kill you, then you'd prolly lose a damn few brain cells.

I think I've been gassed. Doh.

Nothing wrong with Halfords but watch their prices. Sometimes competitive other times not. My most recent purchase was a £15 real leather steering wheel cover which looks great, and is excellent quality. At Halfords.

Hi Mike
I know this is an old thread but interested in your leather steering wheel cover, do you have a photo of it?

If your gas detector would pick up hydrogen, it must be very expensive. A hydrogen gas detector for battery rooms, ups and telecom stand by back up, cost quite a bit. And the gas build up for any dangerous levels, it’s quite a bit. A battery if it boils all of its electrolyte in a van, is still not enough hydrogen air mix for going off.

A carbon monoxide detector will pick up a gassing battery, and they are cheap , and I would say an absolutely essential piece of kit .
I may be OTT as I have 2 in my van as I was once quite ill due to a leaking heater flue. Lucky escape as CO is very lethal in very small concentrations.

Have you actually tested this? A carbon monoxide is designed just for that, not a mixture of gases. Hydrogen detectors are for battery rooms telecom and large ups. Before the detector picks up the fans will expel most of the hydrogen to weaken the mix within a enclosed space.

It's worth reading this discourse on batteries before buying replacements, the guy has a lot of experience and appears very knowledgeable. I thought this article is quite well known in moho circles?

Not tested it as such, but my CO detector kept going off due to a gassing battery under the passenger seat in an old van I had, replaced the battery , no more CO alarm.

Case Study: Hydrogen Gas and False Readings on Carbon Monoxide Alarms​

Carbon monoxide alarms are vital pieces of safety equipment used to protect workers and residents from poisonous carbon monoxide gas. But, did you know that hydrogen gas from charging batteries can set off the alarms as well. The post below is from a real client case, and shows how hydrogen gas can trigger these alarms and potentially become an explosive hazard.
