Lightweight Rechargeable Lithium Batteries 3.7V 20Ah For UPS Battery Replacement
3.7V 20Ah Rechargeable Lithium Batteries for UPS Battery Replacement , Light Weight
Lithium battery VS lead acid battery
1. Lightweight and Small
2. More Efficiency
For quality lithium batteries, discharge and charging are as close to 100% DOD. That means they could charge and discharge completely without losing amps.
3. Increased Cycles Life
You’ll be getting the most possible cycles, around 5000 plus cycles, depending on the battery you choose.
4. Competitive Price
At first, the investment of lithium battery is more than lead-acid. However since you take lifespan, performance and ability into consideration, lead-acid batteries will actually end up costing you more in long time.
5. Low Maintenance
You’ll forget the lithium battery is there due to it needs very little maintenance.
6. A Sleek Design
7. Consistent Discharge Voltage
Voltage is inconsistent when lead acid batteries discharge. But voltage of lithium batteries remains consistent during discharging, making it much more safer to use in terms of protecting electric components.
8. More Environmentally Friendly
Lithium batteries are much more environment friendly
