Duracell, Energizer, JCB, Alkaline are the most common type of household battery. They became popular in the 1970’s, as an alternative to Zinc carbon & Zinc Chloride batteries (e.g., “Heavy Duty” and “General Purpose” batteries). Alkaline have a lot of power and are inexpensive and they usually can’t be recharged.
Standard alkaline don’t work well in high-drain devices (like digital cameras), because they’re not good at pumping out lots of power quickly. They’ll still work, but your battery life will be short. However, most manufacturers have introduced special alkaline which work well in high drain devices, such as Duracell Ultra, Energizer Lithium and Panasonic Evolta and JCB OXI
There’s not much difference in capacity from brand to brand, as long as you’re comparing standard to standard, and high drain to high drain. Consumer Reports found that the spread between the best and worst alkaline was only 9-15% regardless of the brand.
Alkaline lose their voltage gradually — as opposed to rechargeable like NiMH which maintain most of their voltage over the whole charge and then suddenly plummet.
Lots of power – up to 3 to 7 times longer than alkaline
These are designed for very high-drain devices, like digital cameras, mp3 players, motorized toys, and portable CD players (in which they last for up to 10 years). They’re more efficient than standard alkaline for high-drain devices because they can supply the POWER much quicker. But they’re more expensive.
Lithium’s are useful in low-drain devices like smoke alarms — they last so long you can go for years without replacing the battery. When you go through only one battery every several years, you’re not as concerned that it can’t be recharged.
Don’t confuse AA Lithium’s with Lithium-Ion battery packs (like the kind that come with some cell phones and camcorders). Those Lithium-Ion packs ARE rechargeable, but only when they’re installed in the device they’re powering, or in a special recharger. Supreme offer this product in Both Energizer and JCB
NEW Ready to Use (PRE CHARGED) Rechargeable Batteries
By 2005 asked hundreds of consumers if they knew about rechargeable batteries and the reasons why they are still using disposable batteries. The major reason given by the consumers was that they were disappointed by the high self-discharge of rechargeable batteries.
“Whenever you need them they are empty and need to be recharged”, was a common reply.
This complaint about rechargeable batteries was reasonable, because at that time all manufacturers of rechargeable batteries focussed their development on higher and higher capacity, and nobody seemed to care about the self-discharge.
Compared to classic alkaline batteries which keep their charge for years, the available NiMH batteries had rather a high self discharge rate.
Sanyo were the first company to take on board this criticism from the consumers and developed a rechargeable battery with very low self-discharge: eneloop.
While conventional NiMH Batteries suffer from substantial self-discharge, eneloop batteries have a drastically reduced self-discharge.
Ready to use is a most easy to use kind of rechargeable battery, like a disposable battery.
Because they has a very low self-discharge, we can ship the batteries to the retailers in a pre-charged state.
Also in the shops it loses its charge very slowly, which means the consumer purchases a charged battery that can be used immediately.
Therefore as user-friendly as a disposable battery with fantastic power
Zinc Carbon & Zinc Chloride
You know that’s what they are because they’re NOT labelled “alkaline”
They usually say “General Purpose”, or “Heavy Duty”. They were the battery type of choice in the 70’s, before Alkaline were available.
Even recently they were still popular because they used to be a lot cheaper than Alkaline and are great for low drainage items like TV remotes, clocks and any low drainage device.
Nickel-zinc battery 1.6V Rechargeable AA (the most powerful AA on the market)
Nickel-zinc cells have an open circuit voltage of 1.8 volts when fully charged  and a nominal voltage of 1.65V. This makes NiZn an excellent replacement for electronic products that were designed to use alkaline cells (1.5V). NiCad and NiMH both have nominal cell voltages of 1.2V, which may cause some electronic equipment to shut off prior to a complete discharge of the battery because the minimal operating voltage is not provided.
Due to their higher voltage, fewer cells are required (compared to NiCad and NiMH) to achieve a given battery-pack voltage, reducing pack weight, size and improving pack reliability. They also have low internal impedance (typically 5 milliohms) which allows for high battery discharge rates.
NiZn batteries do not use mercury, lead or cadmium, or metal hydrides that are difficult to recycle. Both nickel and zinc are commonly occurring elements in nature. Zinc and nickel can be fully recycled.
NiZn cells use no flammable active material or organic electrolyte.
Properly designed NiZn cells can have very high power density and low temperature discharging performance.
