2025 Battery Voltage Drop. Battery voltage can drop during driving due to several factors, including increased electrical load from using multiple accessories, a bad alternator not providing enough power or a weak battery that can’t maintain its charge. On the pack level, global average battery prices declined from $153 per kwh in 2022 to $149 in 2023, according to the report, which predicts that they'll continue dropping to $80 per kwh by 2026.

The 2025 battery typically has a voltage of 3 volts, while the 2032 battery also has a voltage of 3 volts. Ensure that the replacement battery offers the same 3 volts.
