The first generation rechargeable alkaline batteries were introduced by Union Carbide and Mallory in the early 1970s. [3] [5] Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents, under the trademark "RAM".
For instance, this 12-pack of rechargeable batteries is just $10, with a unit price of $0.86 per battery. A 12-pack from Energizer is almost double the price at $17. A 12-pack from Energizer is ...

Non-rechargeable alkaline and zinc–carbon cells output 1.5 V when new, but this voltage drops with use. Most NiMH AA and AAA cells are rated at 1.2 V, but have a flatter discharge curve than alkalines and can usually be used in equipment designed to use alkaline batteries.
Ditch the disposables and try these expert-recommended rechargeable batteries and battery chargers. You'll save money and create less waste along the way.
The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide (KOH) instead of the acidic ammonium chloride (NH 4 Cl) or zinc chloride (ZnCl 2) electrolyte of the zinc–carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes.
The alkaline sulfur liquid battery is an interesting concept due to the simplicity, low cost, durability, thermal stability (no thermal runaway), low carbon foot print, eliminating the need of rare earth minerals for storage and its applicability to transportation systems. The internal electrolytes and the catholyte gets refreshed continuously ...
Alkaline carbon‑zinc (3 cells): 4.5: Two 6–7 mm wide metal strips +: shorter strip −: longer strip: H: 67 L: 62 W: 22 This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series. In Switzerland as of 2008, 4.5-volt batteries account for only 1% of primary battery ...
