Battery Maintenance Tools

Like it or not, battery maintenance is part of owning most kinds of off-grid solar or renewable energy systems. While sealed cells - found in AGM batteries, gel cell batteries and lithium iron phosphate batteries - are good for eliminating a lot of the drudgery that comes with batteries, it's still a good idea to keep some battery maintenance tools on hand.

Real Goods knows batteries, and we have desulphators, hydrometers, carrying straps, cleaning tools and more for all your deep cycle battery maintenance needs.


"The very best tool for checking your battery's state of health is a hydrometer. This looks like an oversized turkey baster with a graduated float inside it. You must wait at least 48 hours after adding water before you run a hydrometer test."
