There are important things to be taken into consideration when selecting best double aa rechargeable batteries. Choosing the right battery will give you the perfect performance and overall return on investment.
If a site is easily accessible, then aa lithium ion 1.5v rechargeable batteries are a good choice because their low cost and easy availability. If the installation is in a remote area where regular maintenance cannot be guaranteed, then 14.8 volt lithium ion battery packs despite their higher cost.
In areas where batteries often operate at partial state of charge, the addition of carbon additives has successedl in prolonging the life of deep cycle batteries. When batteries operate in off-grid systems or in locations that experience an unstable grid, they are often not fully charged on a regular basis. This quickly shortens the overall life of the battery, but carbon additives can help extend battery life and avoid battery replacement frequence.
3. IEC testing
Look for IEC and third-party test results. Select a manufacturer that employs outside testing companies to ensure the accuracy and validity of cycle life data. Testing to the IEC 61427 standard ensures the batteries meet the rigors of the deep discharge and recharge cycles of renewable energy applications.
Review the capacity of a battery to make sure it is properly rated for the application. A battery with insufficient capacity will over-discharge on a regular basis and have a shorter life. An oversized battery also is an unwise choice because it will cost more for no extra value.
A battery with a low price is attractive, but if bought at the expense of quality and cycle life performance, the cost over time will be significantly higher due to frequent battery replacements. It's important to think about factors other than price when choosing a battery for renewable energy applications.
