Best Rechargeable Batteries In 2021
In our gadget loaded world, power is everything and with our busy lives we need to make sure we don’t run out of ‘juice’. One solution is to swap out your old single-use batteries for rechargeable – not only can you keep powered while saving money over time, but you can help to save the planet too. If this has caught your attention and you want to know more, then welcome to our best rechargeable batteries review!
Rechargeable batteries have been around for quite some time, and today’s versions have well and truly fixed the charging capacity glitches that caused some user frustration in the past. Virtually all rechargeable batteries now use nickel-metal hydride – or NiMH – because of its awesome capacity to hold a charge, and LSD (low-self discharge) batteries, which hold the charge for longer, even when your device is not in use, are the best way to go.
Although rechargeable batteries are generally more expensive than single-use lithium or alkaline batteries, you do get value for money over time so it’s important to think about when and why you should opt for a rechargeable. For slow-drain devices such as remote control, single-use batteries are usually still the best option. But for your high-drain gadgets such as digital cameras or for devices you always use, rechargeable make total sense and they will justify that initial extra cost over time.
So now we’ve got the ‘science bit’ over with, let’s get down to business and power up our lowdown on what we think are the best rechargeable AA and AAA batteries out there.
The Best Rechargeable Battery
For ‘straight out of the pack’ power at a good price for four rechargeable AA batteries, Panasonic’s eneloop come with top green credentials. Pre-charged at the factory using solar power, you are also helping the planet before you even open the pack. And as they use Panasonic’s advanced rechargeable technology, you can get up to an impressive 2,100 recharges, which we reckon could well stack up to five years plus of battery cell life, and that’s based on a daily recharge!
The Panasonic eneloop is the ideal AA battery for frequent use, or for those gadgets you use regularly but which have a habit of quickly eating through battery life. What is also impressive about these Ni-MH rechargeable batteries is how well they hold on to a charge, averaging over 70% even after sitting idle for a year or more.
With a proven ability to perform, even in low temperatures, the Pansonic eneloop rechargeable batteries are particularly well suited to all your outdoor tech gear such as flashlights, cameras, GPS and walkie talkies as they can cope with temperatures down to -4F. They are also a good choice for your everyday high-use items such your PC mouse, keyboards and wireless gaming devices. A reliable AA battery with a long shelf life, the eneloop easily powers into our review’s Best Choice slot. Panasonic Ni-MH rechargeable battery chargers are recommended for this product.

If you are totally taken by the Panasonic eneloop rechargeable batteries (and as they are our review’s Best Choice, we are too), then make your life a total powerhouse with this neat charger pack.
Designed for the popular eneloop and eneloop pro AA or AAA battery, the Panasonic Advanced Cell Battery Charger can also be used to power up more conventional Panasonic Ni-MH rechargeable batteries too. It is also versatile in that it can take any combination of up to four AA or AAA sizes so one for all your gadgets and their different battery needs. The charging unit will accept input voltages ranging from 100 to 240VAC, 50/60Hz and although the charging time is not as fast as others (around seven hours on average), it can take a battery up to full charge. And, with the Ni-MH, you get a reliably good battery life on a single charge.
What we really do like about the Panasonic Advanced Cell Battery Charger is just how compact and easy to use it is. Simply connect the end of the battery into the device and off you go. And, as it charges each AAA or AA battery individually, you can fully charge one battery while topping off another, all at the same time. There are also some nice function touches too, including four individual LED indicator lights and a retractable plug so you can pop it in your travel backpack or pocket for when out and about or on an overseas trip.

For a bumper 12-pack of AA batteries with a high 2800mAh capacity rating, then check out these black and lime bad boys from RayHom.
One of the lesser-known battery makers in our best rechargeable batteries review, their price per battery represents good value. And for everyday items that are not total juice-munchers, they are a practical and cost-effective choice. Despite its 2800mAh rating, the level of their charge is not quite as good as some of the more expensive or well-known brands and so for high power intensity use, such as digital cameras, you may find you are recharging a little more often. But for toys, flashlights and more domestic use, their performance is good enough. For when they are idle, RayHom claim that they can hold a charge for up to three years and their 1200+ recharge life is reassuring. Plus, RayHom AA Rechargeable Batteries come with a 12-month warranty for that extra peace of mind.
