You can buy a cheap car battery charger from a variety of retailers, both online and in physical stores. The most affordable options are typically found at major automotive parts stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, which frequently offer coupons and have store-brand chargers. Walmart and Target are also excellent for budget-friendly models. For the widest selection and competitive prices, online marketplaces like Amazon are hard to beat, especially when comparing user reviews.
When shopping for a "cheap" charger, it's crucial to balance cost with basic features. A trickle charger or a standard automatic charger is sufficient for most personal vehicles. Look for models with automatic shut-off to prevent overcharging, which can damage your battery. While a $25 charger might work, spending $40-$60 often gets you a more reliable unit with safety features.
Here’s a quick comparison of common retail options:
| Retailer | Typical Price Range | Key Advantage | Best For |
|---|---|---|---|
| Amazon | $20 - $80 | Vast selection, user reviews, fast shipping | Comparing features and prices from home |
| Walmart | $25 - $60 | Low everyday prices, convenient locations | Quick, in-person purchase on a tight budget |
| AutoZone | $30 - $70 | Expert staff advice, free battery testing | Getting guidance and buying immediately |
| Harbor Freight | $20 - $50 | Extremely low-cost options (e.g., Pittsburgh brand) | The absolute cheapest option for occasional use |
| Costco/Sam's Club | $40 - $75 | Good value for brand-name models (e.g., Schumacher) | Members looking for trusted brands at a value |
Always check the charger's amp rating. A 2-amp charger is fine for slow, maintenance charging, while a 10-amp charger will recharge a dead battery much faster. Read recent reviews to ensure the model you choose is durable and performs as advertised.
