Last Battery Customer Reviews
We lost power for almost four days after a storm last winter, and it was miserable. After that I started researching backup options but kept running into either $10,000 solar quotes or scattered YouTube videos that didn’t really explain anything. The Last Battery finally laid it out in a way that actually made sense. I went from knowing nothing about battery storage to understanding exactly what I needed to build a small backup setup for our essentials, fridge, a few lights, our internet router. It didn’t cost me a fortune either, just my time and the parts. Wish I’d found this before that storm hit.

I’m not the handy one in my house, my husband usually deals with anything electrical, but I wanted to understand this stuff myself since we’re in an area that loses power a lot in the summer. This guide broke things down step by step without making me feel dumb for not knowing the basics. I appreciated that it explained the safety side just as much as the how-to side. Only reason I’m not giving five stars is I wish it went a little deeper into solar charging specifically, but for the price and what I actually needed, it delivered.
Karen M., Asheville, North Carolina
I’ve been prepping for a few years now and had bits and pieces of battery knowledge from forums, but nothing that tied it all together. The Last Battery was the first resource that actually organized the whole process, battery types, charging, safety, planning, into something I could follow start to finish. Built my first backup system in a weekend after going through it. If you’re tired of piecing information together from twenty different sources, this saves a ton of time
