The battery decides the runtime.
VRLA blocks for short ride-through, LiFePO4 modules for long runtime and high cycles. The chemistry is a lifecycle decision, not a commodity choice.

ReadVRLA or LiFePO4?
Short ride-through in a cool room favors VRLA. Long runtime, tight space, or daily cycling favors LiFePO4. The charger and BMS compatibility decide whether the swap is possible.
Capital cost
VRLA lower per kWh
Usable energy
LiFePO4 80–90% DOD
Weight
LiFePO4 about one-third
Cycle life
LiFePO4 6,000 cycles
Charger
Lithium needs a profile + BMS
Recycling
Lead recycling is established

Selection checks before quoting
| Check | Recommended approach | Risk if skipped |
|---|---|---|
| kW vs kVA | Divide kW by output PF, then add 20–25% | UPS runs at overload |
| Motor starting | Use soft starter or higher overload frame | Trips on start |
| Battery runtime | Use the discharge curve, not Ah ÷ current | Runtime shortfall |
| Charger | Confirm recharge current and time | Battery never fully recharged |
| Input current | Size breaker and cable for full load + charging | Nuisance trips and heat |
| Room | Check floor loading, ventilation and clearance | Installation delay |
