Black 12v ,40ah Capacity ,Reliable Off-grid Lead Acid Solar Battery

In solar systems, lead-acid batteries are the most popular form of battery. Electric scooters, electric wheelchairs, electrified bicycles, marine applications, battery-electric cars or micro-hybrid vehicles, and motorcyclists all use them as backup power supplies for alarm and smaller computer systems, especially in uninterruptible power supplies, UPS. For lead-acid and lead-carbon batteries, a maximum depth of discharge of no more than 40% is suggested, with a maximum of 70% in backup situations. On the other hand, lithium-ion batteries can be depleted from 70 to 90% daily. Lead-acid battery technology has been around for almost a century, so it's a tried-and-true technology that's also quite safe and dependable when properly sized and installed. Lead-acid batteries are still one of the most reliable solutions for bigger off-grid systems, and a properly designed system may generally last 10-15 years or even longer if shallow cycled and temperature controlled.
