User manual seems to contradict potential charging source claims on product page!
The manual that comes with the batteries states “Use Li-ion compatible battery charger.” This contradicts claims on the product page that any USB power supply can be used. The manual implies that the safety protocols provided by such a charger are not present otherwise.
Since many negative reviews contain incidents regarding batteries overheating during charging, it appears that these occurances are likely caused by the use of a simple USB power supply and not a suitable Li-ion capable one as recommended. In the event of problems with the batteries, a simple USB power supply will not limit the power supplied during a malfunction and could result in a bad, if not disastrous, outcome.
This is not necessarily the fault of the consumer, as everyone knows that most people never read the instructions!
I wanted to post this right away due to public safety concerns. I may update this review with more information regarding “the normal stuff” once I’ve had some experience using these batteries.
I’ve only given them 3 stars (average) for now, since I don’t know anything as yet.
I have installed them in a radio controlled (atomic) clock and basic thermometer/barometer station with wireless remote temperature sensors. I installed them without topping them off as they are pre charged. So far, they are functioning as expected, but it’s only been about 9 hours since they were installed.
