Panasonic CF-VZSU1DJS Battery for Panasonic Let's note SV / FV Review
Panasonic CF-VZSU1DJS battery pack (L) for the Let's note CF-SV7, SV8, SV9, SV1 and SV2.
CF-VZSU1DJS is Panasonic's optional large L pack for the Let's note SV line: 6 cell, 10.8V, 6300mAh, about 68Wh by our calculation. Panasonic lists it for the CF-SV7, SV8, SV9, SV1 and SV2, and the same pack is listed for the CF-LV series. Buy CF-VZSU1FJS instead for a black body. It weighs about 0.355kg, 100g more than the standard S pack. We recommend it if runtime matters more than weight.
Fitment answer
OEM confirmed for the Let's note CF-SV7, SV8, SV9, SV1 and SV2. CF-VZSU1DJS is Panasonic's optional L pack: 6 cell, 10.8V, 6300mAh.
Panasonic quotes volts and mAh. The 68Wh figure is our calculation from that rating.
Which laptops this fits
Panasonic lists the L pack for the CF-SV7, CF-SV8, CF-SV9, CF-SV1 and CF-SV2, and the SV manual names it as the optional large battery. Our source notes also list it for the CF-LV series.
It does not fit the CF-FV line, which uses CF-VZSU1PJS and CF-VZSU1QJS.
What to check before you buy
Body colour decides the part number. CF-VZSU1DJS is for silver and black-and-silver bodies. CF-VZSU1FJS is the black body version.
This pack runs at 10.8V while the standard S pack runs at 7.2V. Panasonic lists both for the same machines, so swapping between the two genuine packs is fine.
Weight is about 0.355kg, against 0.255kg for the S pack.
Part numbers this replaces
CF-VZSU1FJS, the black body version. A laptop that came with the S pack (CF-VZSU1CJS or CF-VZSU1EJS) can also take this L pack, per Panasonic's option list.
Safety and handling
If the pack looks swollen, bulges the case or lifts the keyboard or touchpad, stop using the laptop and stop charging it. Do not puncture, bend or press on it.
New lithium packs ship at partial charge because transport rules cap how charged a battery can be in transit. A pack that arrives low is normal, not faulty.
Recycle the old pack at an electronics or battery drop-off point. Never mail a used or swollen battery back to a seller.
Age and condition
Panasonic released the silver version in February 2018 and the black CF-VZSU1FJS in October 2018, per our source data. We found no published date code policy.
Ask any seller for the manufacture date. Old stock can arrive below its rated capacity.
If this is not yours
Read the part number printed on the battery you are replacing and the model code on your laptop's label. If neither appears on this page, this is not your part.
Own a CF-FV? Look at CF-VZSU1PJS or CF-VZSU1QJS. Want the lighter SV pack? Look at CF-VZSU1CJS. For everything else, browse our full laptop parts catalog at /laptop-parts.

FAQs
Is this the biggest battery for the Let's note SV?
Yes, as far as Panasonic's option list goes. The SV line has two genuine packs, the S CF-VZSU1CJS and this L pack.
Can I swap the battery myself?
Yes. Panasonic's support FAQ 0497 covers battery replacement on the SV7, SV8, SV9, SV1, SV2 and LV.
Why does my Let's note say the battery is not genuine?
We have not found Panasonic documentation on how Let's note firmware treats a non Panasonic pack. CF-VZSU1DJS is the genuine part, so buying it avoids the question.
Why did my new battery arrive at 30 percent?
Lithium packs have to ship partly charged under transport rules, so a low reading on arrival is expected. Fit it, charge it to full on the laptop's own adapter, and judge runtime only after a full cycle.
