I go through batteries pretty often, and constantly replacing them adds up fast. That’s what led me to try the inszii 4100mWh Lithium AA Rechargeable Batteries, and honestly, they’ve been a game changer. Each battery charges individually using USB C, which makes a big difference. There’s no need for a bulky charging dock, and you don’t have to guess if they’re done. With traditional chargers like the Energizer ones, the light can stay red and leave you wondering if the batteries are actually fully charged. With these, each battery handles its own charging, so it’s much easier to keep track. Another thing I like is how easy it is to identify a bad battery. Since they charge independently, you can quickly tell if one isn’t performing the way it should, instead of guessing which one in the pack is the issue. The 4100mWh capacity provides solid runtime, and the lithium design helps maintain consistent power output compared to standard rechargeables. Overall, they feel like a more modern solution to something as simple as batteries.

I used these to replace the batteries in my remotes throughout my house, and they all work really well. I'm happy to know that these are rechargeable and I shouldn't have to buy replacements.

The convenience of charging with the USB-A to four USB-C plugs is great and the blinking/steady green LEDs tell the whole story. The internal PCB senses the load and shuts-down the battery power if a short circuit is detected. Use a battery tester having a nominal load applied to check voltage, not an ammeter. Full 1.5 volts are delivered but cuts off to zero when discharged will happen with no warning/dimming of a flashlight. The mAh capacity reads well and should provide reliable power.

These are great as long as you don't get any duds. Out of the 12 I ordered 1 did not charge properly. 3 of these fully charged are lasting an impressively long time in my front door digital lock. The lock gets used multiple times per day and the batteries have to drive the dead bolt motor.

Excellent product. Lasts far longer than a regular AA batteries. Easy to use. Completely compatible for AA batteries. Recharges quickly. I have not noticed any loss during a month of storage. 8 of these have so far replaced 48 other batteries. They will have paid for themselves in less than a year. Go ahead and put them in the cart.

Needed something for my “smart” wifi connected front door deadbolt. Name brand alkaline batteries were only lasting 2 weeks. Top of the line (bunny brand) lithium batteries were only lasting 3 weeks. These batteries are exactly what I needed. They last 5-6 weeks in my deadbolt, longer than the expensive non rechargeable lithium batteries. In three months they have already paid for themselves. Recharging takes 2-3 hours. I am considering buying a second set.
