Free white paper · Voltaplex Life 18650

Your device runs where nobody can reach it. Its battery should tolerate more.

See the test data behind Voltaplex Life: higher measured tolerance to heat and internal damage, more than 1,000 cycles at 1C, and up to 5.7× the lifetime output of the commercial 18650 batteries we tested against.

What the tests measured

Heat tolerance
~20°C higher
First major voltage drop at 147.2°C for Life vs 127.8°C for the comparison cells, in a 5°C/min oven ramp.
Internal-damage tolerance
~10 vs 5–7
Estimated electrode layers a slow-moving nail passed through before thermal runaway.
Cycle life
1,000+ cycles
At 1C charge / 1C discharge to about 80% retained capacity. The tested commercial cells got there within about 300.
Lifetime output
2.6–5.7×
2,918 Ah delivered before reaching 80% state of health, vs 510–1,136 Ah for five commercial cells.

Comparisons are specific to the reference cells and test methods described in the white paper. Abuse-test temperatures are not operating ratings.

Fewer battery replacements. Fewer truck rolls.

Every battery swap on a pole or remote site costs you a technician, a truck roll and your customer’s patience. Voltaplex Life delivered 2.6–5.7× the lifetime output of the commercial 18650s we tested, so each battery does more work before it needs replacing.

Discharge output only, in ampere-hours (charge, not energy). Fewer replacements may follow for a given service requirement, depending on duty cycle and retirement criteria.

Slower capacity loss, cycle after cycle

Line chart of retained capacity versus cycles at 1C charge and discharge. Voltaplex Life stays above 80 percent past 1,000 cycles; five commercial 18650 cells fall to 80 percent within about 60 to 250 cycles.
Published 1C / 1C results, commercial identities anonymized. Test outcomes, not a service-life rating for every application.
Inside the white paper

The evidence your engineering team will ask for

What makes the battery different

How the fibrous cellulose/aramid Dreamweaver separator differs from conventional polyolefin films, and which results it is linked to.

Thermal-ramp results

Repeated oven-ramp measurements with means, standard deviations and representative voltage traces.

Slow-nail penetration

How much progressive internal damage the cell tolerated before runaway, with test conditions and data selection spelled out.

Cycle life at four charge rates

Results from C/2 to 2C charging, plus cumulative output to 80% state of health.

Why retained health matters in a pack

What a teardown of retired e-bike packs showed about weak modules, and how slower capacity loss can preserve operating margin.

Qualification status

UN 38.3 and IS 16046 testing passed. BIS certification in progress, IEC/UL 62133-2 planned.

Results are from Soteria Battery Innovation Group testing as reported in the white paper and are specific to the cells and methods described there. Abuse-test results do not guarantee that a cell cannot enter thermal runaway and are not a substitute for pack-level safety validation. Qualification status as of September 2026.
