The institution offers a wide scope of rechargeable lithium-ion batteries, AAA, AA, C, D, and 9V, arsenic good arsenic type bundles. These are superior to nan older nickel-metal hydride (NiMH) rechargeable batteries, which request their ain chargers.

Paleblue claims nan batteries are bully for astir 1,000 recharge cycles, truthful if you person to complaint them daily, they'll past astir 3 years.

The 4-way charging cablegram intends you tin usage 1 USB-A larboard to complaint each 4 batteries.

They besides recharge rapidly, pinch nan AAs taking astir 2 hours to complaint and nan AAA taking astir an hour. This is overmuch faster than older NiMH rechargeables, which could return up to a time to recharge.
The glowing LEDs connected nan apical are cool!
I for illustration nan 4-way complaint cable, too, though nan truth that it's designed to spell into a USB-A larboard feels a small antiquated (but it's thing that a inexpensive adapter won't solve). Plug nan cablegram in, and nan batteries person glowing LEDs that illuminate during charging and spell retired erstwhile they're fresh to use.
ZDNET's buying advice
It's nan 21st century, and I don't cognize why anyone is still utilizing disposable batteries (outside of a fewer separator cases aliases wherever you request agelong support life, temperature-resistant lithium batteries). And now that you get batteries that past years, accelerated recharging, and nan easiness and convenience of USB recharging, pinch nary abstracted charger required.
Prices for nan Paleble packs are besides rather reasonable -- a 4-pack of AAs is $30, $55 for an 8-pack, and dense users tin pick up a 12-pack for $80. If you person tons of different batteries you request to replace, you tin get an 8-pack of AAs and AAAs for $90, aliases a super-bundle consisting of a 12-pack of AAs, 8-pack of AAAs, a 4-pack of 9V PP3s, and a 4-pack of D-cells for $200.
They're not inexpensive -- truthful don't suffer them -- but they should springiness you years of service, making that first finance a bully deal.
