These extra-high capacity nickel-zinc rechargeable batteries offer amazing value for money. Up to 1,000 charge/discharge cycles can be expected and a single charge outlasts most standard NiMH rechargeable batteries. While 1500mAh NiMH rechargeable batteries will enable you to take 200 photos with a digital camera, 1500mAh Ni-Zn batteries will allow you to take 400 photos! This makes these the ideal choice for today’s power-hungry digital devices such as digital cameras, MP3 players, hand-held games etc. These batteries are rated at 1500mAh with a capacity of 2500mWh and have a voltage of 1.6V – this higher voltage can be useful in various applications. 3 Ni-Zn batteries have the same capabilities as 4 standard NiMH rechargeable batteries.
Rated 4 out of 5 by from Excellent battery I fitted three of these in place of some NiMh cells in a cordless Ikea LED table lamp. The lamp is solar charged but not so good in the English winter. The three NiMh's in series gave 3 x 1.2 volts = 3.6v whereas these Nickel Zinc's give 3 x 1.6 volts = 4.8v That's like having a fourth NiMh for free. I also bought the NiZn charger. If you're continually buying alkaline (non-rechargeable) cells for kids' toys (e.g. Duracell) these will save you a fortune. Just make sure the extra voltage won't damage the gadget - if in doubt, ask Maplin. My Ikea lamp has a constant current chip which protects the LEDs. Good product and well worth a try.

Rated 5 out of 5 by from Very good I use these in an old mobile phone. It was designed to use either a 6V monobloc rechargeable battery (which is no longer available) or 4 x 1.5V AA cells. It will not work on 4 x 1.2V AA cells but works fine with the nickel-zinc 1.6V cells. Nickel-zinc cells have an interesting history. Thomas Edison patented them in 1901 but did not develop them at the time because he was more interested in nickel-iron cells. Dr James Drumm, in Ireland, developed them further in the 1930s and they were used in some battery-electric railcars around Dublin. The production of AA and AAA cells is a much more recent development.

Rated 5 out of 5 by from I zinc we have a winner! I bought these whilst they were on a half price offer at Maplin on the off-chance that they would power my Fuji E550 point & shoot camera for longer periods between charges than the nickel metal hydride batteries do. The problem with those batteries is that they have a lower working voltage than the 1.5 volts or so that alkaline batteries and so are effectively used up quicker - as few as 10 pictures when used with a flash. Of course, the batteries aren't actually flat, it's just that the lower voltage confuses the camera. Anyway... These cells, at 1.6 volts each work superbly well in my camera. They last for hundreds of shots between recharge (about 30 to 40% with flash). The charger (nickel-zinc batteries need their own special charger, also sold at Maplin) is a bit cheap looking (and the battery compartment is slightly too small so it ripped the plastic coating on the cells, but it's no big deal), but it works. Over all, I am very happy indeed with this product.

Rated 4 out of 5 by from Ni-Zn rechargeable batteries. I have bought quite a number of these batteries and use them in devices that have wireless communication built in as the lower voltage of standard NiMh cells gives low output. Unfortunately a small number have developed faults. They discharge rapidly after recharge and if used straight from the charger will fail after only a few minutes use. They seem to develope internal leakage and no amount of discharge/recharge cycles will correct the fault. I have taken a total of three sets back to MAPLIN and they have changed then without question. According to he assistants no one else has had this problem!!!!

Rated 1 out of 5 by from Thus far these batteries and their chargers have proved to be profoundly disappointing. 1. Significant out gassing on first use. This was in a sealed torch. The internal pressure generated was such that I needed mole grips to unscrew the torch. No subsequent outgassing following first recharge 2. Charger does not give clear indication of charging. Newly discharged batteries do not light up the charging lights until they have been in the charger for 5 minutes. The charging lights are very dim so even if the charger is working correctly it is still difficult to see in daylight. 3. Recharged batteries only seem to last about 10-15 minutes before becoming discharged again so there is something wrong with the charger or the batteries. I have 12 AA batteries and three chargers and the problems are consistent among the whole lot.

Rated 4 out of 5 by from Solved a problem... I needed a PC-tethered camera that was much higher resolution than a 'HD' webcam, but inexpensive. That ruled out a dSLR. I eventually got a cheap Aiptek mini-camcorder that could tripod-mount, stream as a webcam, then take a 5mp 'still' on demand. The PC software even complied with Win 8 ! Snag was the device could not draw power from the USB tether, so rapidly consumed pair after pair of alkaline AA batteries. Trying NiMH and other 1.2V chemistries quickly gave 'low voltage' alerts, then shutdown. I'd remembered seeing these 1.6 V AAs. Though expensive, they proved a perfect match to the task. One quibble; There seem to be slight size differences between different sets of cells. My first set had to be wrestled in and out of their special charger. The second set just slips in... Hopefully, such variations will vanish as production ramps up. Meanwhile, try not to mix different sets !!

Rated 4 out of 5 by from Fine... Everything was fine batteries worked ok, even thrashing them at 3.5A for 5 minutes only made them a bit warm. The charger charged them, my mazelli flyback driver discharged them. Capacity seems to be OK... No problems, as expected.

Rated 5 out of 5 by from Best Rechargeable AA Batteries These batteries are excellent. They are the best I have ever used. I have them fitted to my car's Dash-Board Camera, my Nikon D7000 Battery Grip, My Yongnuo YN-560 2 Flashgun and my Bushnell Camera Trap. I am a professional wildlife photographer and it is great to be able to be out in the wilds, hours away from a charger and have batteries that hold their charge like these do. At this price for 4 they are not cheap. Especially when I needed to buy 8 packs of them. You have to buy the specific charger for these batteries. The charger was reasonably priced and it charges the batteries quickly. It isn't the best looking piece of kit but That is an irrelevance, it works great. One downside is that they do not make a charger that can be plugged into the accessory outlet in a car but the batteries hold their charge for so long you would be unlikely to need that facility. Overall they are the best on the market, that i know of.

Can these batteries be recharged in an ordinary Duracell charger for AA size.

Asked by: John
A charger like the one below would be required. http://www.maplin.co.uk/p/nickel-zinc-aa-standard-battery-charger-n38ka

Are they affected by heat either hot or cold? Would they lose their charge quicker in temperatures greater than 30deg C for example?

Asked by: Gareth
All batteries are affected by hot and cold tempratures and therefore will affect the operation of the battery/s.

Do they self-cutoff at safe voltage to avoid cell damage on discharge

Asked by: Davet70
This would be down to the charger, not the batteries.

Are these batteries rechargeable using a standard NiCd NiMH charger?
