Lead-acid batteries generally require about 8–10 hours for a 100% charge, whereas lithium-ion batteries require a minimum charge time of 2–3 hours. On the contrary, lithium-ion batteries come up with a cycle span of around 5,000 cycles, thus providing five times more longevity than an ordinary lead acid battery. Lifetime CyclesĮven the best lead-acid batteries have a cycle span of 500–1,000 cycles, and if you’re frequently tapping into your battery bank, that could mean that your batteries may need a replacement within a year or two. However, in the case of lithium-ion batteries, self-discharge varies between 2% and 3% and if you leave them unplugged for almost a season. The self-discharge rate of a lead-acid battery is 33%, which is no doubt enormous.

Well, it’s a little bit technical, so instead of boring you with lengthy deets, let’s cut it short: Internal reactions within the batteries make them lose charge over time and ultimately reduce their capacity. Well, it’s a hell of a lot of work to do, isn’t it? Lithium-ion batteries certainly suit you the best if you’re a lazy bum. Monitoring the discharge limits (keep a check that they don’t fall by the 50% charge limit).Corrosion cleanup (check if they are clean so the charge terminals don’t get corroded after some time).Watering (you have to keep optimum water levels).They require frequent maintenance in terms of: However, lead-acid batteries are an absolute bummer.

To begin with, lead-acid batteries are significantly less expensive than lithium-ion batteries in the short term, but over the length of the battery’s life span, lithium-ion batteries look like a more feasible option. With that aside, let’s do a side-by-side comparison of both batteries from different perspectives: Cost Provides energy backup when the main battery starts dying!
