Product overview

• High 1.6V cell voltage (higher than alkaline, NiCd and NiMH Batteries)
• Extra-high capacity 550mAh / 1000mWh Ni-ZN rechargeable batteries
• High current discharge ability
• Lower self-discharge due to 50% higher energy density than standard NiMH rechargeable batteries
• Better performance than standard NiMH rechargeable batteries
• Last much longer than standard rechargeable batteries
• Recharge up to 1000 times
• Environmentally friendly rechargeable battery: 0% mercury, 0% lead, 0% cadmium
• Uses Zinc in place of toxic cadmium
• Perform well in low temperatures
• Suitable for temperatures between -20°C to +65°C

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 550mAh NiMH rechargeable batteries will enable you to take 200 photos with a digital camera, 550mAh 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 550mAh with a capacity of 1000mWh 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.

Please note: These batteries require a Nickel Zinc AA Standard Battery Charger (N38KA).

Rated 2 out of 5 by from I have tried them in my camera my portable media player and a couple of other devices the camera and media player stated over voltage and would not even switch on or stated battery error on screen and switched off i have a 21 led torch that now only operates on 7 leds 14 have burnt out whilst using the batteries and i suspect they will only work in none voltage protected devices so beware the device is not protected and the batteries are over the required voltages therefore could potentially damage the device. fully charged these batteries deliver 1.83 to 1.92 volts under load it will be lower but not much

Rated 1 out of 5 by from I was sold these batteries as being capable of roughly the same life as non-rechargeables. They actually last less than a quarter of the time.The quoted charge capacity is quoted as milli watt hours rather than the industry standard of milli ampere hours and needs to be divided by 1.6 for comparison purposes. They also need a special dedicated charger to add to the price. Useful if you NEED 1.5 or 1.6 V to operate your equipment. Otherwise use standard NiMh.

Rated 3 out of 5 by from Don't buy unless you really need the extra voltage! Bought charger, AA & AAA packs about a year ago, mainly for some 'always-on' gadgets with LCD displays that go dim quickly with 1.2V NiMH. Had one NiZn AA fail fairly soon after purchase (replaced by Maplin) then one AAA fail more recently. Maplin staff generally seem to make out that they are doing you a big favour if they replace something, but isn't their stuff supposed to be fit for purpose! Also the charger 's LED indicators do seem a bit erratic - the cradle's contacts for the AAA size aren't well designed but this may only be part of the problem. Considering buying another pack (at offer price) but not really sure yet whether it wouldn't be better to buy std 1.5V non-rechargeables.

Rated 4 out of 5 by from Found battery charger channel lights flicker a lot while when I first charged new AAA batteries. I would recommend cleaning battery terminals prior to charging, I used a fibreglass brush. It solved my problem.

Rated 5 out of 5 by from Work great in Hi drain equipment. My cree tourch shines like a star for ages with these aaa babies in it, much better than good alkaline or nimh. These ni-zn will put out a high voltage(1.5v) for their whole charge, whereas nimh and alkaline batteries voltage will drop too low(1.2v) to be of any use in Hi drain equipment when they are only half flat.

Rated 1 out of 5 by from Not suitable to replace NiCd or NmHi batteries I was sold these in-store as a suitable replacement for NiCd batteries in cordless phones. Fortunately I read the information on the back before opening them, as it clearly states they must be charged in a special charger for Nickel Zinc, and cannot be charged with NiCd or NmHi chargers. Returned to the store for a refund. These Nickel Zinc batteries are clearly a separate system with their own chargers etc, and are higher voltage (1.6V) so should be regarded or sold as replacements for other types.

Rated 2 out of 5 by from Buy a dedicated charger - and read up on them!! These are not compatible with Nicad or NiMh chargers, so if you want to use them go the whole hog and buy the charger. Also, they appear to have a lesser life cycle of charge/discharge, so only buy if they are an absolute requirement.

Can you use them in cordless phones?

Asked by: Peter
These are NOT suitable for such usage. They require a special charger to recharge them and the charger/base unit for a cordless phone is NOT suitable.

Can you mix NiZn batteries and NiMH batteries in a device?

Asked by: jackie27
No this can cause damage to the items.

I have your N28NC, and see that the package suggests charging with a specific charger. I have a standard charger switchable between NiMH & NiCd, can I use this, and what setting should it be. Thanks
Asked by: steve j
You would need Nickel Zinc charger, please see order code N38KA
