Ampere Time vs SOK Battery Spec Comparison

Ampere Time no longer exists as a separate brand. It rebranded to LiTime on December 14, 2022, and the Ampere Time 12V 100Ah is now sold as the LiTime 12V 100Ah Classic. So "Ampere Time vs SOK" today means LiTime vs SOK.

The short answer: the LiTime Classic is cheaper per cycle and lighter. The SOK wins on warranty, winter charging, and serviceability. Every spec below comes from litime.com and sokbattery.com, verified November 6, 2026.

What Happened to Ampere Time?

Ampere Time was the earlier brand name of Shenzhen LiTime Technology. LiTime's own rebranding notice confirms the switch to litime.com. Same manufacturer, same engineering, new name. If you own an Ampere Time battery, warranty and support now run through LiTime.

That matters for this comparison. A pre-2023 Ampere Time spec sheet may not match what ships today. This page uses the current LiTime Classic specs as the Ampere Time successor.

Where Each One Wins

Cold weather: SOK

This is the biggest difference. The LiTime Classic has no low-temperature charge protection, according to LiTime's product page. The owner must keep it from charging below 32°F. The SK12V100H has both a cutoff and a heater. SOK says the heater draws from the charger, not from the cells.

If your battery sits in an exterior bay through winter, the Classic is the riskier choice. LiTime does sell low-temp-protected and self-heating models. Those cost more and are covered in our LiTime spec sheet.

Cost per cycle: LiTime, narrowly

At current prices, the gap is less than a cent per cycle. LiTime publishes 6,000 cycles at 80% DoD. SOK publishes a 4,000 to 8,000 range without stating DoD. Using SOK's midpoint gives $0.062 per cycle versus LiTime's $0.056. If you take SOK's low end, its cost rises to $0.092.

Warranty: SOK

SOK's warranty policy lists 7 years for the SK12V100 and SK12V100H families, and the coverage is transferable. LiTime lists 5 years. Note that SOK's own SK12V100PC product page still says 5 years and 3,000 cycles in its description, while the site banner claims 7 years. Confirm the term in writing before buying the PC model.

Weight and fit: LiTime

The Classic weighs about 3 to 6 pounds less. It uses a standard Group 31 footprint. The SOK metal case is shorter but wider, so measure your tray.

Serviceability: SOK

SOK's detachable cover lets you replace the BMS or individual cells. That is rare at this price. LiTime batteries are sealed units.

Spec Conflicts We Found

Manufacturer pages do not always agree with manufacturer spec sheets. We report both rather than pick one.

Item	Source A	Source B	What we did
SOK SK12V100H continuous discharge	Product page: 170A	Spec sheet: 100A	Listed both. Size fuses to 100A unless SOK confirms 170A for your unit
SOK SK12V100H weight	Product page: 27 lb	Spec sheet: about 30 lb	Listed both
SOK SK12V100PC warranty	Product description: 5 years	Site banner: 7 years	Flagged. Confirm before purchase

Which Should You Buy?

Pick the LiTime Classic if your battery stays in a heated space, you want the lowest cost per cycle, and you need a Group 31 drop-in.

Pick the SOK SK12V100H if you charge in freezing weather, want a longer transferable warranty, or want a battery you can repair yourself.
