Review on Battery Charger Rechargeable Batteries Indicator Household Supplies by Erika Martin

Nickel metal halide batteries are the preferred batteries for small AA and AAA powered devices. While 1.2 volts may seem like a problem since alkaline batteries are rated for 1.5 volts, in most cases this is actually not the case. Yes, there are some sensitive devices that will not work well or will not work when the voltage drops below 1.5V. This is usually a bad or cheap design. Standard alkaline batteries are only 1.5 volts when fully charged and the voltage drops throughout their life, being as low as 1.2 volts at half-life and continuing to drop to 1 volt or less. In contrast, nickel halide remains at its nominal 1.2 volts for the duration of the discharge cycle. A more sophisticated charger is required to charge this type of battery, so the charger that comes with it will most likely have a good charging design. The KISS acronym, which people say means "keep it simple, stupid," also applies to the charger. It has no switches, no fancy controls, and an LCD that looks like a battery chart on a laptop or cell phone. The graph has a battery outline with 3 bars that appear in sequence as it loads and flashes as that level loads. The outline of the battery makes it easy to see which direction the batteries need to be inserted into the charger. If the flashing stops when charging is complete. There is a note in the little manual that it cannot be used to charge alkaline batteries. No other types are mentioned so this could be other than nickel-cadmium types, although I'd be much less keen on trying to make lithium types, but most AA and AAA lithium types aren't meant for charging. Another fact about batteries in general. . Lithium batteries can be stored at or above room temperature for ten years or more before being switched on and will retain most of their charge. For this reason, utilities and other industries use them as a backup for equipment such as standby capacitor bank controllers. They're great for devices you don't use much but when you want them to work, e.g. B. emergency lighting in case of car breakdown etc. These batteries are slightly different. After a month, they can be discharged by 40 percent or more at room temperature. If you choose to charge and store them, they will hold a 90% charge for several months if kept in a dry, sealed container in the freezer. Allow them to warm to room temperature before use. Literally in an hour of sitting here writing reviews all 8 batteries were almost fully charged based on the strips. During that time, all but two have stopped flashing, and the rest are on the final strip, so they'll be done soon. highlighted.
