Review: Dual Voltage 110-240V - The device seems well-made, and the lights show the process it goes through to test the battery. I live in the U.S. but needed a 24/7 battery charger for our car overseas, as I couldn’t find any battery tender-like devices in that country. I’ll be using this with a UK type G adapter and 220V. It’s surprising to find a dual-voltage battery tender, especially here in the U.S. I haven't tested it with any kind of electronics meter but this appears to be better made than the actual Battery Tender devices I already have.
Review: Excellent product. - I have owned an Optimate 4 for several years to charge motorcycle batteries and it still performs excellent. So, I bought this Optimate 7 for charging car or truck batteries. It works just as good as the 4, but I found that the LED indicators are not as intuitive as the 4 (it does not have the 3 charging level indicators which gives you an idea of the charging duty cycle). I also found that when the charger indicates the battery is fully charged, I would call it a "minimal" full charge. Good enough to start a car, but not at the maximum of what the battery could charge to.

### ⭐⭐⭐⭐⭐ Good Charger
*by P***M on July 23, 2025*

Bought this specifically for use on a depleted 2 yr old lead-acid battery. This charger appears to have brought that battery back to fully functional condition. Can't say if any older design charger could have done the same. With sky-rocketing prices on common lead-acid batteries, it is good having a charger you can (or want to) trust. Bought this based on good experiences with previous purchase of LiFePO4 charger from same company.
