What to know about Battery Tender 022-0148-DL-WH

Four independent 1.25A charging circuits in one IP65 unit for maintaining up to four 12V batteries at once. It is the collector's or multi-vehicle garage pick for winter storage. Expensive, with only a 2-year warranty.
Editorial notes

Why it stands out

Why we like it

If you store several vehicles, one plug and four independent banks are tidier than a pile of single chargers. Each bank runs its own 1.25A circuit, so a full battery on one does not affect another. The Drive's 2023 maintainer guide names it Best Overall and says it can maintain a car, truck, SUV or power boat, and Road & Track picks it for multiple batteries.

It is IP65 rated, ETL/cETL listed and CEC/DOE compliant. Amazon shows it in stock now, but it has often sold out, so buy early in the fall.

What to know

Skip it if you store one or two vehicles. Lithium support is stated inconsistently by the manufacturer, and the warranty is only two years. Two-vehicle owners could consider the NOCO GENIUS2X2, which costs less but has no independent test.
Performance

Score breakdown

Long-term maintenance performance

How safely and reliably it holds a battery at full charge for months: automatic float/pulse maintenance, overcharge protection, temperature compensation, behavior after power loss, ability to restart on low batteries.

8.5
Each bank runs its own float maintenance, so one bad battery doesn't affect the others.
Battery compatibility

Supported voltages (6V/12V), chemistries (flooded, AGM, gel, LiFePO4), and rated battery capacity relative to the vehicles people store (motorcycles to trucks/RVs).

7.5
Four 12V batteries; Amazon lists LiFePO4, but the manufacturer states lithium support inconsistently; no 6V.
Ease of use & hookup

Set-and-forget operation, clarity of status LEDs/display, lead length, ring-terminal/quick-disconnect harness, mounting.

7.8
One outlet for four vehicles, with an LED per bank.
Durability, weather & cold resistance

Build quality, IP rating, rated low operating temperature for unheated garages, warranty length and reported failure rates.

7.5
IP65, but only a 2-year warranty.
Safety, certifications & energy

Third-party electrical safety marks (UL/ETL), spark-proof and reverse-polarity protection, CEC/DOE efficiency compliance (maintenance-mode draw), recall history.

8.5
ETL/cETL listed and CEC/DOE compliant (manufacturer page).
Value

Price relative to capability, warranty and the battery sizes it can serve.

6.8
Expensive up front, reasonable per bank; stock is volatile.
