🔌 Tenergy TN600 Wall Smart Charger: Fast Charging for 6V & 12V Sealed Lead Acid Batteries Review

A 12V lead-acid battery only took overnight to charge. When I plugged it in the indicator was red and after 24 hours it turned green - the battery is charged and ready to go!

Bought to replace a broken Garmin finder charger. It seems up to the task - charged the ice fishing tackle several times this winter and all is fine.

Sent the first one back, a new one was sent very quickly. The second didn't work either. There are no instructions at all, so I'm still not sure if it's a malfunction or operator error. I sent the second one back for a refund.

I have used it once and I find it very good and comfortable. I don't need a big heavy charger and it works great. I also like the insulated alligator clips, they are built to last. Great product and great price.

Great people like to charge their batteries before driving the jeep. It's faster than plugging in a regular charger and can be used for any battery you need. Charge while riding another, the extra charger and battery is worth it.

Extremely easy on my Fishfinder battery. I lost my old one and needed to charge the battery. It charges slowly to avoid damaging the battery and simply turns off when it's done. Just connect the red and black to the correct terminals and leave it. This works very well.

The first charge didn't work at all, a replacement was sent. It arrived very quickly and was functional. Although the original item was defective, I am satisfied that the replacement was delivered on time and found to be working.

This is a very good smart charger for small 6 or 12 volt batteries with automatic voltage adjustment. This is normal for batteries up to around 10Ah, delivering an output current of 500mA. It can probably handle large batteries, but takes a long time to recharge from a significant discharge.

The product arrived working but there was a loose item in the sealed box. However, the product worked perfectly for 5 months and was used to charge a 12V gel cell battery. The product failed after 5 months, no power. We opened the sealed case and found a small ferrite bead floating inside. No idea if that was the reason for the cancellation.

We have this to charge the 6 volt batteries that we use to power our electric goat fence. It worked fine when we first charged the batteries (for initial setup), but it doesn't charge the battery we need now when we switch batteries. I missed the return window and have since bought another one from a different company which will hopefully last longer.
