General Battery in Baltimore: Where to Buy and Replace Batteries for Everything You Own
General Battery is a single-location, independent retailer on East Pratt Street that stocks automotive, marine, power tool, hearing aid, and household batteries alongside charging equipment and accessories. It's the rare Baltimore store that treats batteries as a category worthy of depth rather than a convenience aisle, and its inventory and staff knowledge make it genuinely useful for anyone who needs a specific battery fast or wants to avoid big-box guesswork.
What General Battery actually is
The store occupies a modest street-level space in the Fells Point area and operates as a family-run battery specialist, not a general electronics or automotive shop. The focus is entirely on batteries and related gear: everything from AA and AAA cells to 6-volt and 12-volt automotive units, plus marine cranking batteries, rechargeable packs for cordless tools, and hearing aid button cells. The staff can identify a battery type from a photo or part number and discuss real trade-offs between chemistry types (alkaline vs. lithium vs. nickel-metal hydride). This matters because buying the wrong battery type for your application wastes money or damages equipment.
Products and pricing
General Battery stocks Duracell, Energizer, Panasonic, Rayovac, and house brands across common consumer sizes. A pack of Duracell AA alkaline cells runs around $5 to $7 depending on pack size; Energizer Max AA is similar. Rechargeable NiMH batteries (Panasonic Eneloop brand, among others) start around $12 to $15 per pair for AA or AAA. Automotive batteries range from $80 to $200 for standard 12-volt passenger-car cranking batteries; marine batteries and specialty types like golf-cart units cost more and require a phone call or visit for pricing. Hearing aid batteries (size 10, 13, 312, 675) are $4 to $6 per pack of four or six. Power tool batteries (for DeWalt, Makita, Milwaukee tools) vary widely by voltage and capacity but typically range from $40 to $120. The store also sells battery chargers, from simple two-cell AA/AAA chargers at $15 to $25 up to multi-bay smart chargers at $60 to $100. Prices reflect current stock and should be confirmed by phone at the store.
How General Battery compares to other Baltimore options
Chain retailers like CVS and Walgreens carry batteries but limit selection to mainstream consumer sizes and brands, with no staff ability to troubleshoot odd-ball applications. Target and Walmart stock a wider range but still orient toward convenience shoppers, not people comparing lithium versus alkaline trade-offs or trying to find a replacement for a discontinued marine battery. Automotive retailers like Mr. Tire or Firestone have strong automotive battery inventories but treat batteries as a sideline; they will not stock hearing aid cells or power tool packs. Home Depot and Lowe's offer batteries as part of a much larger assortment, making it harder to get focused advice. General Battery is the only Baltimore store where batteries are the entire focus, and where staff time is dedicated to application-specific recommendations rather than processing high volume. Choose General Battery if you own hearing aids, marine equipment, or cordless tools, or if you want to understand battery chemistry before a purchase. Choose a chain if you need a single AA pack at 11 p.m. and convenience trumps expertise.
Who it suits and who it does not suit
General Battery suits anyone with a specific or unusual battery need: marine enthusiasts, people who wear hearing aids, DIYers with multiple cordless tools, and anyone who wants rechargeable options explained clearly. It also suits customers who trust local ownership and want their money staying in Baltimore. The store does not suit people looking for a one-stop shop (no groceries, no household goods, no clothing) or those who need batteries in bulk for institutional use at a steep wholesale discount. It is not a self-service warehouse; the experience relies on asking questions and waiting for staff input.
What the first visit involves
Walk in with your dead battery, its packaging, or a photo of it, or with the model number of the device it powers. Staff will identify the correct replacement, explain why a certain chemistry makes sense for your use (alkaline for smoke detectors, rechargeable for cameras, lithium for high-drain flashlights), and ring you up. If it's an automotive battery or an unusual type, expect a brief conversation about fitment and warranty. The store is small enough that wait times are usually under five minutes, even during weekday afternoons.
Hours, parking, and logistics
General Battery is open Monday through Friday, 9 a.m. to 5 p.m., and Saturday 10 a.m. to 2 p.m., and closed Sunday. Street parking is available on East Pratt Street; a public lot is one block away. Call ahead (verify the number with current directory listing) if you have a specialty request like a hard-to-find hearing aid battery size or a marine battery you need to source. The store does not have a website or email ordering system; phone calls and walk-ins are the way to reach it.
General Battery fills a real gap in Baltimore's retail landscape by treating a mundane category with seriousness and stocking depth that chains cannot justify. If you own equipment that needs the right battery, not just any battery, this is where to start.
