- •Slightly larger than typical alkaline batteries, which may cause fit issues in very tight compartments

Bottom Line
If you're looking for a reliable, long-lasting battery that can withstand extreme temperatures and store for years without losing potency, these Energizer Ultimate Lithium 9V batteries are a solid choice. They are especially good for smoke and CO detectors, reducing the frequency of replacements and ensuring safety.
