AGM Sealed Lead acid Solar Batteries

​(I make a commission for purchases made through the links below)
Heavy, cheap, easy to use and they work! Typically will last about 3-5 years. Slower charge rates than lithium, much heavier, and they cost  way ​more in the long run.
​Also keep in mind that the usable capacity of lead acid is only half that of a lithium battery.
If you only need a battery that will last 3-5 years or you are on a budget, the batteries below are your best options:
