Question 1

What battery does the Satellite 305 use?

Accepted Answer

The Satellite 305 uses a removable 6-cell lithium-ion battery in the 10.8 to 14.4 V range, with capacity around 31 to 98 Wh depending on the exact configuration. Common part numbers in this family include PA3817U-1BRS, PA3819U-1BRS, and PA5023U-1BRS. Because part numbers vary by build year, check the code printed on your original battery before ordering. Prices for Satellite L replacements run from $42.99 to $68.99.

Question 2

How do I find the right battery for my Satellite L model?

Accepted Answer

Find your exact model number, including the digits after the L (for example L655 or L50-A), then match it to the part number printed on your original battery. The Satellite L category covers 63 distinct part numbers across about 3,545 compatible models, so the exact code matters. Look for entries like PA3817U-1BRS or PA5110U-1BRS on the back of your current pack, then confirm voltage (10.8 to 14.4 V) lines up with what your laptop expects.

Question 3

How much does a Satellite L replacement battery cost?

Accepted Answer

Satellite L replacement batteries cost between $42.99 and $68.99. Where your battery falls in that range depends on capacity and cell count, since packs span about 31 to 98 Wh and include both 6-cell and higher-capacity 9-cell options. A standard 6-cell unit like the PA3817U-1BRS sits toward the lower end, while higher-capacity packs cost more. Match your exact part number to confirm pricing for your specific model.

Question 4

Are Satellite L batteries interchangeable?

Accepted Answer

No, Satellite L batteries are not universally interchangeable. With 63 distinct part numbers across the line and voltages from 10.8 to 14.4 V, a pack built for one sub-series will not always fit or power another. For example, the PA3817U-1BRS used in earlier models is different from the PA5184U-1BRS used in later L50-A builds. Always match your exact model and the part number on your original battery rather than assuming a similar-looking laptop takes the same pack.

Question 5

What differs between the Satellite L sub-series batteries?

Accepted Answer

The main differences are voltage, capacity, cell count, and physical fit. Across the Satellite L line, packs range from 10.8 to 14.4 V and about 31 to 98 Wh, with most using 6 cells and some offering 9-cell capacity. Older models commonly use families like PA3817U-1BRS, while later models move to codes such as PA5110U-1BRS or PA5184U-1BRS. Some newer builds use an internal battery that requires opening the case, while earlier ones use a removable bay pack.

Question 6

Where do I find the battery part number?

Accepted Answer

The part number is printed on the label of your original battery, typically on the side that faces into the laptop. On removable models you slide the pack out of the bay to read it. Look for a code like PA3817U-1BRS, PA5023U-1BRS, or PA5110U-1BRS. You can also check the sticker on the bottom of the laptop for your exact model number, then use both together to confirm the correct replacement among the 63 part numbers in this category.

Question 7

Can I replace the Satellite L battery myself?

Accepted Answer

Yes, on most Satellite L models you can replace the battery yourself. Removable packs like the PA3817U-1BRS slide out of an external bay and lock back in with a latch, no tools needed. Later models from around 2014 to 2016 may use an internal battery in the PA5185U-1BRS style, which requires opening the bottom case and disconnecting a connector. Check whether your model uses a removable or internal pack before you start, and match your exact part number.

Question 8

What are the signs the battery needs replacing?

Accepted Answer

Common signs include much shorter runtime than when the laptop was new, the charge dropping suddenly, the system shutting down even when the meter shows remaining percentage, or the battery no longer holding a charge at all. You might also see the laptop run only when plugged in. If your Satellite L pack, such as a PA3817U-1BRS rated around 10.8 to 14.4 V, no longer lasts through normal tasks, it is likely time for a replacement in the $42.99 to $68.99 range.
