Can Rechargeable Batteries be used in Smoke Alarms

David — Wed, 27 Jan 2010 18:19:38 +0000

Smoke Alarm Batteries

Yes, but perhaps the question should be:

“Should I use rechargeable batteries in a Smoke Alarm”

One of the problems with conventional rechargeable batteries is the self discharge – at between 1% and 2% per day this is higher than the drain from the smoke alarm itself.

So a conventional rechargeable will be pretty much flat after just a couple of months or so. This in itself is not such a problem as you can just take it out, recharge it and put it back in.

The real problem is how quickly the voltage drops off as the rechargeable battery approaches exhaustion. In most single use batteries the voltage drops off at a fairly consistent rate, so the low battery warning beep you get in a Smoke alarm can go on for weeks. Rechargeable batteries hold their voltage really well right to the end, but then drop off very quickly, this means you get the low battery warning for a much shorter time – This can be just a day or so, perhaps even just a few hours.

So unless you check your smoke alarm battery ever day, there is a real possibility of the rechargeable battery going flat without you ever knowing! – not a great thought.

So I think the answer is “Yes you can, but you probably shouldn’t“.

Instead I would suggest you use conventional Alkaline type batteries or, for extra piece of mind, why not look at using the ULTRALIFE Lithium PP3 type battery, this can last up to 10 years in a Smoke Alarm.

Battery Chargers and Rechargeable Batteries – Our Best Christmas Deals

David — Tue, 15 Dec 2009 10:17:53 +0000

We always have great deals on rechargeable batteries and battery chargers, but which are the best ones to look at this Christmas.

PC17 with eneloop

Ansmann PowerLine 5 Mobile

GP 8 + 4 ULTRA Alkaline

We have a couple of great deals on the PC17 Travel Battery Charger, one bundled with a set of 4 x AA2500 mAh batteries at an amazing £10.99, the other bundled with the superb Sanyo eneloop Low

Self Discharge (LSD) AA batteries at just £12.98!

The PC17 battery charger is not the fastest or smartest, but at this price for a travel charger you can’t go wrong.

If you want to be able to charge the full range of battery sizes (AAA, AA, C, D & PP3), then you can’t go wrong with the Ansmann PowerLine 5 Mobile. This intelligent battery charger will charge and monitor each battery slot independently (except the PP3 slots which are trickle charged) and drop to a trickle charge when the batteries reach a full charge. The Ansmann PowerLine 5 Mobile comes with a 240V mains adapter and a 12V in car lead making it really versatile and fantastic value at just £19.99.

Don’t forget we also have a full range of alkaline batteries with the 12 pack of GP batteries offering great value.

Low Self Discharge (LSD) Rechargeable Batteries

David — Thu, 26 Nov 2009 16:51:25 +0000

Ansmann maxE

All rechargeable batteries lose charge over time once they are removed from a charger, this is known as “Self Discharge”.

For conventional NiMH type rechargeable batteries this is generally between 1% and 2% per day, though can be higher for the first few days.

As a result a rechargeable battery could have lost something like 50% of its capacity after a month of storage. This is often seen with digital cameras, where you put some freshly charged batteries in, take a few pictures, then put it away for next time. Next time ends up being a month or 2 later and the camera batteries are dead – really annoying.

Low Self Discharge (LSD) Rechargeable Batteries tend to have a self discharge rate of more like 1% – 2% per month making them much more suitable to this type of usage.

The down side of Low Self Discharge (LSD) Rechargeable Batteries is they tend to be a lower capacity, typically 2000mAh – 2100mAh for the AA size. This means they won’t last quite as long as a high capacity conventional rechargeable battery would if used intensively soon after charging.

As a rough “Rule Of Thumb” for AA rechargeable batteries, the cross over point is something like 2 – 3 weeks. So if you would ordinarily exhaust 2700mAh rechargeable batteries in less than 3 weeks, then stick with them, but if it would be longer than this then consider the Low Self Discharge (LSD) rechargeable batteries.

Low Self Discharge (LSD) rechargeable batteries are best for:

Clocks
TV Remote Controls
Torches
Flash Receivers
Wii Controllers
Xbox Controllers
Kids toys
Casual use cameras
Solar Garden Lights
Other low drain or occasional use products

Rechargeable Batteries and DAB Radios

David — Mon, 16 Nov 2009 08:35:36 +0000

DAB Radio

DAB Radios are real battery eaters, especially the older ones.

We often get calls from customers who have bought a DAB radio that uses 6 x C Size or D Size alkaline batteries and are only getting something like 8 or 10 hours from a new set of Duracell Alkaline batteries.

This costs something like £9.00 each time they have to change the batteries for another set of Alkaline cells, let alone the environmental cost of throwing away all those batteries.

From a rechargeable front this can be a little tricky to solve if the DAB radio uses 6 C or D size batteries, as most chargers only cater for 4 cells at a time.

One solution is to use the Ansmann Energy 16 Battery Charger (as this can charge 6 C or D size batteries at a time) and a set of the Ansmann maxE 8500mAh D size (or Ansmann maxE 4500mAh C size) batteries. This would cost something like £150.00 – yes a lot of money, but only equivalent to having to buy 16 or 17 sets of Alkaline batteries. That’s just 160 hours of radio time if you only get 10 hours from a set of Alkaline batteries.

A cheaper alternative would be to use the Ansmann Powerline 5 Mobile (or even 2 of them to enable you to charge all 6 cells at the same time!) and a set of the CAMLINK 8000 mAh Ready-2-Go batteries. This would cost more like £65.00 – £85.00, that’s just 7 – 9 sets of alkaline batteries!

NiMH Rechargeable Batteries

David — Tue, 03 Nov 2009 16:34:16 +0000

2850 mAh AA

Nickel Metal Hydride or NiMH, Ni-MH type rechargeable batteries are higher capacity replacements to the generally poor performing Ni-Cd (Nicad) type rechargeable batteries.

These are available in all five battery sizes (AAA, AA, C, D & PP3) and can usually replace normal disposable batteries in just about every application.

Typical battery capacities are:

AAA (LR03)         800 mAh to 1100 mAh
AA (LR06)            1300 mAh to 2850 mAh
C (LR14)                2500 mAh to 4500 mAh
D (LR20)               2500 mAh to 10000 mAh
PP3 (9V)               150 mAh to 250 mAh

Performance of NiMH rechargeable batteries is in a different league to the early Ni-Cd rechargeable batteries, and anyone who hasn’t tried rechargeable batteries recently really should give them another go.

NiMH rechargeable batteries tend to perform particularly well in higher drain applications like digital Cameras, Flash Guns and radio controlled toys.
