Portsmouth waterways
Portsmouth Harbor and Little Harbor are near the river mouth, and New Castle is just across. Lift bridges cross the river to Kittery, Maine, and the Isles of Shoals lie offshore.
Most boats are hauled for winter. The Portsmouth Naval Shipyard, one of the oldest in the country, sits on an island in the river on the Maine side. The Great Bay estuary, upstream, is a large tidal bay popular for striped bass and kayaking. The Isles of Shoals, about six miles offshore, draw cruisers and anglers in summer. Boats moving through the harbor must time their trips with the tide, because the current can run several knots, and a stalled engine in that current is dangerous. Keep the cranking battery healthy and test it before the season. Charge batteries fully before winter storage.
Choosing the right battery
Center consoles and offshore boats
If you run twin or triple outboards, replace cranking batteries as a matched set. AGM batteries in Group 31 size are a dependable starting choice for big outboards, and many Portsmouth owners add a lithium house battery so the electronics never touch starting power. Check your engine maker’s cranking amp requirement before you choose.
Sailboats and cruising boats
Sailboats and cruisers in Portsmouth rely on a house bank for lights, refrigeration, instruments and an autopilot, plus a starting battery for the auxiliary engine. A bank of 6V golf-cart batteries wired in series is a traditional choice; lithium banks like the EPOCH 12V 300Ah or Battle Born 100Ah give more usable capacity and recharge faster from solar or the engine.
Houseboats and cruisers
Many cruising boats around Portsmouth Harbor are upgrading to lithium for faster charging and more usable capacity. Check your charging system first.
What people run and fish for in Portsmouth
Striped bass, mackerel and groundfish are fished. Sailboats, cruisers and fishing boats share the harbor.
Keeping batteries healthy in New Hampshire
Strong currents call for reliable cranking batteries.
New England and Long Island boats are usually hauled for winter. Charge batteries fully before storage, and keep lead-acid batteries on a maintainer or remove them. A discharged lead-acid battery can freeze and crack.
The boating season is short, so it pays to have batteries ready in spring. Test them before launch, and replace any that won’t hold a charge.
How shipping to Portsmouth works
- Free lithium freight: lithium batteries over $150 ship free, curbside, to the lower 48.
- Parts and chargers: free shipping when your cart subtotal is $150 or more.
- Lead-acid and AGM: free curbside truck freight to the lower 48, the same as lithium.

- Inside delivery, or hard-to-reach spots like marinas with restricted access, may cost extra, so a home or business address is usually best.

FAQ
Do I need a heated lithium battery for Portsmouth?
Only if you plan to charge in freezing weather. Standard lithium batteries should not be charged below 32°F. Batteries with internal heating, like several EPOCH models and the Dakota Lithium DL+ 135Ah, warm themselves before charging. For normal spring-to-fall use with winter storage, a standard lithium battery is fine.
How do lead-acid batteries ship?
Lead-acid and AGM batteries ship free by curbside truck freight to the lower 48, the same as lithium.
Do chargers and accessories ship free?
Chargers, accessories and lithium batteries of $150 or less ship free when your cart subtotal is $150 or more. Otherwise a flat shipping rate applies, shown at checkout.
Can you ship to my marina?
We can ship to most addresses, but marinas with restricted access or no way to receive freight may cost extra or need special arrangements. A home or business address is usually easiest. Contact us before you order if you want to ship to a marina.
