Get PriceTherefore, in cyclic applications where the discharge rate is often greater than 0.1C, a lower rated lithium battery will often have a higher actual capacity than the comparable lead acid battery. This means that at the same capacity rating, the lithium will cost more, but you can use a lower capacity lithium for the same application at a lower price.
Get PriceDeep cycle batteries are more expensive than regular lead-acid batteries, but they have a longer lifespan and can withstand frequent deep discharges. Technical Aspects Influencing Battery Longevity When it comes to lead-acid batteries, there are several technical aspects that significantly influence their longevity .
