Review on 🔌 Tenergy TN136 4 Bay Smart 9V Charger by Denise Aramori

I need to be able to charge 4 9V NiMH batteries at the same time for my smoke alarms. This model is a huge improvement over the multi-battery charger I bought at least 8 years ago. My old charger had a capacity of 29V but didn't recognize the battery level for 9V. The old one was based on a 14 hour timer. It is great! Based on my 250mA battery rating, I can charge all four in under 3 hours. I also really like that each battery has its own gauge and battery level sensors. The indicator is only red or green, but that suits me.
