It is not recommended to use regular alkaline batteries in solar lights, even temporarily. Here’s why:

1. Designed for Rechargeable Batteries

• Solar lights are engineered to work with rechargeable batteries. They have a charging circuit intended to recharge batteries via the solar panel. Regular alkaline batteries are not designed for recharging and can be damaged if charged.

2. Risk of Leakage or Explosion

• Charging alkaline batteries can be dangerous. The charging circuit is not equipped to handle non-rechargeable batteries, leading to potential leakage, rupture, or even explosion due to internal pressure buildup.

3. Poor Performance

• Alkaline batteries have lower capacity. They will power the light for only a short period before depleting, unlike rechargeable batteries which are designed to handle the demands of solar lighting systems.

4. Consistent Battery Replacement

• Replace all batteries with a matching set of rechargeable ones. Mixing different battery types or combining old and new batteries can lead to malfunction or reduced performance.

Recommendation: Instead of using alkaline batteries, replace the rechargeable battery pack with NiMH or LiFePO4 batteries that match the voltage and size specifications. This will ensure proper functionality and efficient charging from the solar panel.
