This is a great Battery. have had for a few months and used in a solar generator system. I ran 250 watts of stuff for hours at a time with no power fluctuations. Takes a charge very well from my MPPT charger, I have also had it in storage and it holds the voltage really well for weeks.

Replaced old wet cell battery in my RV with this one. Night + day difference! This one rarely gets below 70% charge overnight, even running our heater fans. It is heavy but I love that it’s no maintenance. Recommended.

Using this battery set for an off-grid 750 watt solar system and so far they perform well. Looked at other battery options but in the end went with this product. 400ah only works out to 3-4 amps per 10 hours at 120 volts but if people are realistic about what they really need these should work well. I bought these because I got tired of the expense and noise of the generator and am very pleased. I am a master electrician, certified in several states so I know a little bit about what I talking about. If you have reasonable expectations, this is a good product.

Fast delivery. Carefully packed. Pleased with the quality.
