The company offers a wide range of rechargeable lithium-ion batteries, AAA, AA, C, D, and 9V, as well as assorted bundles. These are superior to the older nickel-metal hydride (NiMH) rechargeable batteries, which need their own chargers.
Each kit comes with the batteries, a 4-way charge cable, and a plastic box to hold the batteries.
The batteries are identical in terms of size, voltage, and power to the alkaline batteries they replace. This is important, and you’d be surprised how variable some poor-quality batteries are — I’ve literally seen some that are too big or too small to fit properly.

Paleblue claims the batteries are good for about 1,000 recharge cycles, so if you have to charge them daily, they’ll last about three years. For more modest applications where they’ll last a couple of months, these batteries will last for many years, and you’ll probably lose them before they die.
ZDNET’s buying advice
It’s the 21st century, and I don’t know why anyone is still using disposable batteries (outside of a few edge cases or where you need long shelf life, temperature-resistant lithium batteries, $55 for an 8-pack. If you have lots of different batteries you need to replace, you can get an 8-pack of AAs and AAAs for $90.
They’re not cheap — so don’t lose them — but they should give you years of service, making that initial investment a good deal.
