# CEENR 6.0Ah DCB200 Replacement Lithium-ion Battery

- Manufacturer: CEENR
- Tier: C
- Price: $35.00
- Stated capacity: 6 Ah
- Amazon listing: https://www.amazon.com/dp/B0DJXVD8X8?tag=lithiumsteppe-20
- Battery page: https://www.lithiumsteppe.com/battery/ceenr_6ah

## Summary

Cannot recommend CEENR batteries due to their poor electrical construction. Skip these packs that skimp on current-routed PCBs and instead use soldered wire harnesses.

## Ratings

- **Honesty**: 3.6/5 — Actual capacity is 4.9 Ah, vs 6 Ah advertised.
- **Durability**: 0.5/5 (teardown 0.5/5, cycling 0.5/5) — Cheap wire harness heats up and melts the pack, even when within standard heavy-use operating regime
  - Teardown notes: Typical trash-construction that uses undersized, loose wiring and solder joints prone to melting
- **Capacity**: 4/5 — 4.9 Ah capacity.
- **Power**: 0.5/5 — Pack came with high-quality, cleanly-branded cells, but they were ~8 years old, plus the thermistor on this pack did not operate correctly in the performance test.
- **Safety**: 3/5 — A poorly installed thermistor shut down the pack prematurely during testing, likely culprit is the inadequate wire harness design.

## Testing statistics

- Stated capacity: 6 Ah (108 Wh @ 18 V)
- Measured capacity: 4.9 Ah (87.8 Wh @ 18 V)
- Pack internal resistance: 67.6 mOhm
- High-power cycles survived: 1

### CSV format

1 Hz samples. Lines starting with `#` are run metadata (test profile, battery profile, instrument identity, Arduino DAQ channel labels); the first non-`#` line is the column header. Columns vary by run date — Arduino DAQ columns (tc/v/r_ntc/fault) appear on runs logged since 2026-05-11.

- `ts_unix / ts_iso` — sample timestamp (Unix seconds / ISO-8601 local time)
- `elapsed_s` — seconds since test start
- `voltage_v` — pack voltage, V (4-wire remote sense)
- `current_a` — discharge current, A
- `active_power_w` — discharge power, W
- `discharged_ah / discharged_wh` — integrated charge / energy removed
- `phase / target / cycle` — load-profile phase name, setpoint, loop count
- `tc1_C..tc4_C` — Type-K thermocouple temperatures, Celsius (nan = channel absent, disabled, or faulted)
- `v0_V` — DeWalt C3 cell-tap voltage, V
- `v1_V` — DeWalt TH thermistor-pin voltage, V
- `r_ntc_ohms` — pack NTC thermistor resistance, ohms, derived per-tick from v1_V and pack voltage (DeWalt tool thermal cutoff reference: 2140 ohms)
- `fault1..fault4` — MAX31856 status byte per thermocouple, hex (00 = healthy)

## Photos

- Headline photo: photos/headline.jpg
- Teardown 1: photos/teardown_1.jpg — Deformation and melting of the pack due to me abusing the poor electrical construction
- Teardown 2: photos/teardown_2.jpg — Current-carrying wire harness is completely melted, leaving bare copper and a melted pack body
- Teardown 3: photos/teardown_3.jpg — Wiring harness poorly engineered, consistent with other cheap shadow-brand packs
- Teardown 4: photos/teardown_4.jpg — Closeup of the harness/cell junction, where cells are subjected to extreme heat from the harness
- Teardown 5: photos/teardown_5.jpg — Cell label: LGABHG21865
