Coast USB-C Rechargeable lithium ion 1.5 volt AA and AAA batteries

[Hooked on Fenix]

Found out Costco is now carrying Coast Zithion-X batteries. It was an 8 pack of 4AA and 4AAA with a 4 way USB-C charge cord. Pack was just under $28. I was curious so I bought a pack. AAs claim 2400 mAh 1.5 Volts 3 Watt hours. AAAs claim 750 mAh 1.5 V 0.94 Wh.

Tested one AA using an old Fenix L1D Q5 on Turbo (120 lumens). 2 hours 7 minutes to shut off. There was some flickering early on. I suspect the battery didn't like the heat build up and throttled down a bit.

Tested a AAA using an Olight i3E EOS 120 lumen version. Lasted 1 hour 7 minutes to shutoff. Not bad. However, these batteries would not fit inside my 2AAA l.e.d. Maglite. Too tight to fit. Both sizes are normal length for AA and AAA though.

Now I'm tempted to get the Pale Blue USB-C rechargeable 4 pack of 123As I saw at REI's website and get more use from my 1 and 2 123A lights that don't work with rechargeables. I'll have to wait until I have more money for that though.

It's nice to see more of these types of batteries becoming available in stores. I'm seeing Cs, AAs, AAAs, and 123As so far. Be nice to see USB-C rechargeable Ds at some point made from a large lithium ion battery.

Edit: It appears Paleblue did make Ds as well as Cs. I think they could have done a lot better on capacity in those sizes though.

Tested Fenix E01 v.2 with the AAA and got 1 hour 20 minutes to shut off on high.

Tested 4Sevens Quark Pro 2A on 85 lumen high using 2 of the Coast batteries. Runtime was 6 hours 27 minutes until shutoff. At 6 hours 10 minutes, light started flickering on and off a bit, moreso at 6 hours 23 minutes. Took batteries out to cool down and gave light a ten minute break before putting them back in as the light was pretty warm. Batteries only lasted 4 more minutes. Seems the batteries causing flickering is a warning that the batteries have become too hot. Probably like a thermistor throttling back the power to reduce the heat. Since alkalines last 5 hours at this setting, 6 hours 27 minutes is pretty good for usb-c rechargeable batteries.

They are quite a bit more expensive than eneloop. What advantage do they have outside of the USB charging?

Next time I'm at Costco I'll look for these.

How are they more expensive than Eneloops? They are $28 for 4 AAs, 4AAAs and a charge cord. That's $14 per 4 pack plus the cord. Eneloop Pros can cost $20+ per four pack. The AAs are 2400 mAh in this kit. Regular Eneloops are 2000 mAh. The AAAs are comparable in capacity to regular Eneloops on paper, but since voltage is regulated at 1.5 volts, the light stays on longer before shutting off. I got longer runtime on high in my Fenix E01 v.2 with these batteries than an alkaline or Eneloop. If you go to REI or somewhere else and buy these batteries, yes they are expensive at $30 per 4 pack. At Costco, they are less than half that price.

When I look on Amazon, they're about $25 for 4 batteries.

Do you have a Costco card? They are $28 for 4AAs and 4AAAs and charge cord there in store. $35 on Costco's website.
