What Batteries Are Compatible With An LR1130 Battery?

LR1130 batteries are alkaline 1.5V button cells with direct compatibility to AG10, LR54, G10A, 389, 189, and 390 models. These equivalents share identical dimensions (11.6mm diameter × 3.1mm height) and voltage, making them interchangeable in devices like calculators, watches, and medical thermometers. Brands like Panasonic, Philips, and Tenergy offer these replacements, though performance varies. Pro Tip: Always verify physical fitment—even slight size mismatches (e.g., LR44’s 11.6×5.4mm) can cause device incompatibility.

What are the key specifications of LR1130-compatible batteries?

All LR1130-compatible cells deliver 1.5V nominal voltage with a 40-45mAh capacity. Their standardized 11.6mm diameter and 3.1mm height ensure seamless replacement. For instance, AG10 batteries from Panasonic exhibit ≤3% voltage variance across temperatures (-10°C to 60°C), maintaining stable performance in critical devices like glucose monitors. Avoid zinc-air variants despite matching dimensions—their 1.4V output and oxygen-dependent chemistry make them unsuitable replacements.

Which brands offer reliable LR1130 equivalents?

Top-performing options include Panasonic LR54 (1200-hour lifespan), Tenergy AG10 (20-pack bulk value), and Maxell G10A (ISO 9001-certified consistency). In temperature-sensitive applications, Varta 389 batteries maintain 1.48V after 12 months storage—crucial for emergency devices. Budget picks like Sony SF-1130 work for non-critical gadgets but show 15% faster drain in high-drain LED toys. For example, the Epson EL-1197II calculator runs 11 months on Panasonic versus 9 months on generic brands.

How do battery chemistries affect compatibility?

While alkaline (LR) and silver-oxide (SR) versions share dimensions, their discharge curves differ. Silver-oxide SR1130SW maintains 1.55V longer but costs 3× more—ideal for precision instruments. Alkaline LR1130 drops from 1.5V to 1.2V over 80% discharge, whereas silver-oxide stays above 1.45V until depletion. Never mix chemistries in series configurations: pairing alkaline AG10 with silver-oxide SR54 creates dangerous reverse-current risks in multi-battery devices.

Are there regional variations in labeling?

Yes—AG10 (IEC), 389A (ANSI), and G10A (JIS) all denote the same cell. Japanese devices often specify “G10A” while European appliances use “LR54”. Cross-reference using diameter/height measurements when documentation lists obsolete codes like Eveready 189. Pro Tip: Keep a 3.1mm spacer when substituting thinner batteries (e.g., 2.6mm SR44)—improper contact causes intermittent failures.

What devices commonly use LR1130 batteries?

Primary applications include digital calipers (Mitutoyo 500-196-10), laser pointers, and hearing aids. In automotive TPMS sensors, 389A variants survive -40°C to 125°C extremes. Gaming controllers like PlayStation VR remotes require LR54s for their balanced 0.2mA standby draw. For pet trackers, lithium-coated AG10s last 4× longer than alkalines—crucial for outdoor GPS units.
