Lithium, tubular and gel behave very differently. Knowing how helps you choose the right one for your budget and backup needs.
The three you'll see
- Lithium (LiFePO₄): long life, deep discharge, low maintenance, higher upfront.
- Tubular: affordable, repairable, shorter life, needs maintenance.
- Gel: sealed and maintenance-free, but shorter life and shallow discharge.
The metric that matters
Compare cost per usable kilowatt-hour over the battery's life, not just the sticker price. Lithium usually wins there despite costing more upfront.
