4.9 out of 10

It stores 1,280 Wh, the typical size for a 12 V battery, so it scores 5 on capacity.

At 23.32 lb on Redodo's spec table it holds 54.9 Wh per pound, so it scores 6 on efficiency.

Redodo rates its BMS at 100 A maximum continuous discharge, 1.0C on 100 Ah, with a 500 A surge on the spec table and 330 A for one second in its manual, so it scores 5 on operating range.

Redodo rates it for 4,000 cycles at 100% depth of discharge, with no end-of-life capacity in its spec table or manual, so the 4,000 is scored and taken one rung down for the missing end point, and it scores 6 on lifespan.

Built-in heating pads warm the cells from as low as -4°F (-20°C) before charging resumes at 41°F (5°C), given at least 15 A of charge current, and it carries an IP65 rating and allows four in series and four in parallel, but has no Bluetooth and no CAN or RS485 port, so it scores 6 on features.

Redodo cites only CE, FCC, RoHS and UN38.3 for model AE-A14114C-0D; Intertek's UL 1973 record for its 100Ah siblings does not name this self-heating model, and no listing turned up in the Intertek, UL, LabTest, TÜV SÜD, TÜV Rheinland or SGS directories or on the California Energy Commission list in October 2026, so it scores 2 on verification.

Better on verificationRedodo 12V 100Ah Group 31 Battery$249.99Scores 6.0

Redodo's warranty policy gives its 12 V batteries of 20 Ah and up 5 years, and its depreciated refund after the first 12 months is a refund schedule rather than a prorated term, so it scores 6 on warranty and support.

Heating runs from -4°F to 41°F (-20 to 5°C): below 32°F (0°C) charging current goes to the pads first, and charging resumes at 41°F (5°C); the pads need a charge current of at least 15 A, and heating takes about 30 to 60 minutes from 14°F (-10°C) and 70 to 100 minutes from -4°F (-20°C). It charges and discharges from -4°F (-20°C), to 122°F and 140°F respectively, with internal resistance of 40 mΩ or less, an IP65 protection class, a flame-retardant ABS case and M8 terminals with 5/8 in (16 mm) bolts and insulating caps.
