duracell 18500 rechargeable solar battery

Within a few days it has more than paid for itself in recovered batteries (which have since been through a few recharge cycles with no issues whatsoever). It recharges every battery I can lay my hands on, and even brought to life the dead ones I had. Either way, the one I bought was fine.Īs for performance, it's great. Maybe there's been an increase in quality control, or maybe it was a bad batch. I'd read some reviews about the New i2 having poor solder joints, but I took mine apart to take a look and everything looked fine to me. The device comes with an easy to read display that shows what's going on during the charging process. Most of the time you just put a battery into the charger and away it goes, but you can play with the charging currents if you want to optimize charging. The New i2 features an array of safety features, including overcharge protection and thermal cut-outs, which offer peace of mind. This model can only take two cells at a time, so if I have more recharging to do, I'd get the four-cell i4 version instead, which you can pick up for about $20. Must read: This $35 accessory is a must-have for MacBook, iPad Pro, and Windows laptop users It's not all that new - launched in 2016 - but I thought I'd give is a go since it made some bold claims.Īnd since it was only a little more than $10, I didn't have much to lose. I've been a long-time user of Nitecore chargers, so I was excited when I came across the 'new' Intellicharger New i2. So I have a few dead rechargeable batteries from random devices - flashlights and tools primarily - and looked into getting a charger that could resuscitate them. And once discharged, need persuasion to come back to life. I find that the newer IMR batteries - lithium manganese rechargeable - cells are particularly prone to being completely discharged by some devices. But as good as modern batteries are, they can still die and refuse to be recharged While most smartphones, tablets, and laptops don't have batteries that are easily replaceable, many devices do indeed come with batteries that can be swapped out.
