Buying guide – Best Rechargeable Batteries

Rechargeable AA batteries are a great solution for many people, there’s no need to buy expensive batteries again and again when you can simply recharge them. Before you buy a set of rechargeable batteries, make sure you consider the following things.

Types

You must know that there are 3 different types of rechargeable batteries available in the market. NiCd rechargeable batteries have lower voltage and have the capacity to be recycled for about 1000 times or charged per day for 3 years. This is old technology and considered cheap. Next is the advanced Li-ion batteries that offer full voltage without any memory effect problem. However, Li-ion rechargeable batteries are not accessible in standard voltage sizes and need a special charger. NiMH is the most common type of rechargeable AA or AAA batteries available. They are a great alternative for disposable alkaline batteries and replace primary batteries if you rely frequently on battery power. Also, you may notice NiZn composition batteries.

Capacity

The price difference between the two sets of rechargeable batteries depends on the capacity. Charging capacity (mAh) is mentioned on the battery itself as well as the packaging. More number of charge capacity in the battery means it can deliver more current and power the device longer. You’ll find a capacity range of 1300-2900mAh for AA batteries while AAA batteries usually have 500-1000mAh capacity.

Remember that the battery’s actual capacity is always lower than the rating mentioned on it. Not all batteries with similar mAh rating will last the same duration. Opt for low-mid range capacity ratings for devices like a cordless phone, remote controls, garden lights, etc. For AA batteries, the low-mid capacity range is 800-1300mAh while AAA batteries have 400-800mAH. Devices that need high-capacity batteries include Walkman, remote control cars, toys, radios, flashlights, and cameras. High capacity for typical AA and AAA rechargeable batteries is 1900-2700mAh and 900-1000mAh respectively. If you want to buy batteries for high-drain devices, go for higher capacities.

Cycles

You can reuse or recharge batteries from 400-1000 times on full discharge and charge that depends on battery usage. They break down slowly on each use, therefore look for a rechargeable battery with 1000 cycles ratings so it can last longer.

Self-discharge

Self-discharge is very common among rechargeable batteries; they tend to lose electrical charge even when not in use. This not only decreases batteries’ shelf-life but also stop full-charge. It can be avoided by placing batteries at a lower temperature to slow down self-discharge. Lithium-ion is the rechargeable battery that shows the least self-discharge (about 2%) while NiMH has 30% self-discharge per month.

Choose a rechargeable battery that has a low self-discharge rate if you plan to store them or use it for low-power devices. Rechargeable NiMH batteries with ‘stay-charged’ technology effectively hold charge preventing self-discharge.

Pre-charged

Some rechargeable batteries come with some amount of charge in them when sold. Labeled as pre-charged, these rechargeable batteries are ready to use straight from the packaging just like single-use disposable batteries. This is a convenient option for those who right away need to use the newly bought rechargeable batteries. However, all other standard rechargeable batteries lack this pre-charged feature and require a charge before using.

Battery charger

Rechargeable batteries require a separate kind of battery charger to charge them. There are many different types of intelligent fast chargers available in the market to charge various battery sizes. Make sure to buy the correct charger to charge AA or AAA type batteries. A standard battery charger can hold and charge 4 AA batteries at a time.

Price and packaging

Rechargeable batteries usually come in a pack of 4, 8, 12, and a set of 16. Batteries are not something that you buy every day, so it’s better to purchase the 8-pack batteries at an economical price. You can charge one set of batteries while the remaining batteries are in use. Remember that a standard battery charger can only hold and charge 4 AA batteries at a time.
