Yes, they are finally available. A company called Kentli has released AA and AAA rechargeable lithium polymer batteries that output 1.5 volts.
DURACELL ALKALINE BATTERIES

A regular AA battery which is a an alkaline battery has a 1.5 nominal voltage charge, but when it is fresh or brand new, it will have 1.65 volts. That is the full capacity of an alkaline battery but when it reach about 1.4 volts, it will be considered dead.
A typical alkaline or NiMH battery in the standard “AA” size has about 2000 to 3000 mAh (or 2 to 3 Ah).

Q: Can I use a higher rated mAh battery in my electronic device (i.e. 1800mAh vs. 2000mAh)? A: Yes, the mAh rating will give you longer run times between recharges. The higher rated mAh of a battery has no effect on electronic devices other than they allow longer term use.
A reading of 1.3 to 1.5 volts means the battery is good. A brand new battery might show a higher voltage level. Reading at 1.6 or slightly higher is not uncommon, and this is the reason for setting the DCV to a level of 20 volts as the maximum threshold.
If the cell is good, you should know, by the capacity and size of the cell, what the chemistry of the cell is. If the batteries have a covering on them and it's green, then it's NiMH. Unless it's a Sanyo or Panasonic industrial NiCd cus a lot of them had green wrappers too .
It is difficult, if not impossible, to slow charge a NiMH battery. Harmful overcharge can occur when charging partially or fully charged batteries, even if the battery remains cold. The same scenario occurs if the battery has lost capacity and can only hold half the charge.
Rechargeable batteries are of the same sizes (AA, AAA, C, D, Sc and 9V) and are intended for everyday use are the throwaway or primary batteries people use.
Your RadioShack 9.6V/7.2V RC Ni-Cd/Ni-MH Charger can fully charge 7.2V/9.6V nickel-cadmium (Ni-Cd) and nickel-metal hydride (Ni-MH) cord-connected battery packs used in many remote- controlled cars, in about 5 (for Ni-Cd) or 7.5 (for Ni-MH) hours.
For 1.5v AA or AAA primary batteries, 1.3v "under load" as tested by your DMM is considered dead. For 1.2v Nicad or NiMH AA or AAA rechargeable batteries, 1.0v "under load" is considered dead.
2 Answers. Test the battery under load after charging. For AA and AAA, use a resistor of about 10 ohms, or a small incandescent flashlight bulb, in parallel with the multimeter. NiCd or NiMH cells should be ~1.4 volts, though different cell chemistries may give a range of ~1.35 to ~1.5 V.
When a battery is repeatedly overcharged, small crystals form on the electrodes, inhibiting their ability to complete that important chemical reaction. As a result, the battery's voltage drops. For both conditions, the standard advice is to discharge your batteries completely, then recharge them.
The main difference between rechargeable and non rechargeable batteries is that rechargeable batteries can be put to use again after have been fully discharged once, while non rechargeable batteries cannot be charged again once they discharge fully.
Voltage: 1.5 Volts. Duracell CopperTop Alkaline AAA batteries are available in packs of 4, 6, 8, 16, 20, 24.
Answer has 5 votes. The letters on a battery give the size, in height and width, of the battery. AA means “50.5mm x 14.5mm.” The later the letter the larger the battery. "D" is larger than "C", etc. "A" is larger than "AA" is larger than "AAA".
ELI5: Why are batteries (Such as AA, AAA, D, ect.) so expensive? Because people need them and will pay the prices charged. The price has stabilized at the highest point people will accept.
AAA batteries can replace AA batteries by enlarging the size of the casing.
Duracell batteries typically sell for about a $0.03 to $0.10 per battery premium (depending on type, quantity, sales channel) compared with their name brand peers (e.g., Energizer, Amazon Basics, Rayovac, etc.). They can get this because they have an excellent battery and Duracell has great brand recognition.

- 33% lighter than alkaline batteries – ideal for travel, camping, hiking and use in high-drain game controllers, handheld electronics and power tools.
brief overview of all the different types of AA and AAA batteries today: Alkaline, Rechargeable Alkaline, NiZN, NiMH, NiCD, and lithium batteries (rechargeable and non-rechargeable) that are available in today's market.
Alkaline AAA batteries weigh around 11.5 grams (0.41 oz), while primary lithium AAA batteries weigh about 7.6 g (0.27 oz). Rechargeable nickel–metal hydride (NiMH) AAA batteries typically weigh 14–15 g (0.49–0.53 oz).
The Amazon battery is a surprisingly good battery though. You will probably barely notice the difference in capacity, so if you don't want to waste time shopping around then its a good choice. I also performed the same test on Duracell Copper Top, and Energizer Max.
Energizer Ultimate Lithium
When comparing rechargeable AA batteries, Gizmodo found that Duracell lasted longer (5 to 6.5 hours) than Energizer batteries (2 to 3.5 hours). Both companies's batteries are NiMH; the Duracells are 2000 mAh and the Energizer batteries are 2200 mAh.
11 amps. An average AAA alkaline battery contains about 1000 milliamp-hours, so therefore, the batteries would last a maximum of 9.09 hours.
Rechargeable nickel–metal hydride (NiMH) AAA batteries typically weigh 14–15 g (0.49–0.53 oz).
Use. AAA battery life particularly depends on use. By comparison, a digital clock will run for about six months with a standard battery, a year with an alkaline or a rechargeable but up to two or three years with lithium.
Even though the physical material used for AAA batteries are less, the shipping, handling and promotion and cost of sales are the same or more, and mass production of larger quantities leads to lower costs. Some battery powered gadgets require 2 AA batteries, some 4 AA batteries, and some require AAA batteries instead.
How to select the correct battery pack (General Knowledge)?
- First of all, you must get to know your device:
- Decide battery pack voltage you will choose.
- Decide Battery pack's Capacity ( mAh or Ah)
- Battery capacity is depended on how long you need to run your device ( hours ), which can be calculated as the follow:
Highest Capacity Rechargeable AAA: EBL (8-Pack)
If you're trying to get the most out of your high power electronics, then you should grab some of EBL's rechargeable AAA batteries. They have a 1,100 mAh capacity, and EBL claims that they can endure 1,200 recharge cycles.
