Home Battery Lifespan: How Long Will It Really Last?
Home Battery Lifespan: Setting Real Expectations
Home battery lifespan for LFP systems is typically 10-15 years or 6,000-10,000 cycles at 80% depth – far longer than lead-acid.
What Affects Life
| Factor | Effect |
|---|---|
| Depth of discharge | Shallower = longer |
| Temperature | Cooler = longer |
| Quality | Cell grade matters |
Maximize It
- Keep daily DoD near 80%.
- Install in a temperate, ventilated space.
- Buy from a lithium battery manufacturer with documented cycle data.

Frequently Asked Questions
Do batteries expire if unused?
They slowly self-discharge and age; periodic cycling and ~50% storage is best.
Is 10 years realistic?
For quality LFP with normal use, yes – capacity fades to ~70-80% by then.
