Question from JWM
Just purchased the Lenz reB 1200 lithuim packs along with the socks and currently charging the packs - it appears in the Charging Time for the 1800's is 7-9 hours is this correct - does the first charging time differ from recharging times after use?
Answer from Jeff
Hello JWN,
Good Question. Time your first charge and subsequent charges and please post here. I searched and we do not know where we got that charging time. I did find this piece --
Please completely charge and discharge the lithium packs three times. After that, experience shows that an improved capacity should be achieved. If this is not the case, please contact our service centre.

Question from Nate
Is there a physical size difference between the rcB1200 and the rcB1800? What are the physical dimensions of each battery pack and how much does each one weigh?
Answer from Patrick C

Unfortunately we only have the rcB 1200 in stock and I can not open the packaging without damaging it! The catalog does not list weights. If you can email us at I will contact the company to see if I can get you some answers. Sorry I couldn't be more helpful at the moment!
Answer from greg s
It looks like Lenz updated their website with more details:

1200: 85 grams and 8.5 cm x 5.5 cm x 1 cm
1800: 95 grams and 8.5 cm x 5.5 cm x 1.5 cm
Answer from Teddy Young
Hey y'all! I busted out the calipers and scale, here are some more numbers for you.

82 g each
3.7V, 2400mAh, 8.88Wh

105g each
3.7V, 3600mAh, 13.32Wh

Dimensions seem pretty accurate, thickness might be ~0.5 cm thicker in reality. Batteries weighed without 2.5 g electrical contact cover, proprietary USB-A charging cable weighs 63 g and charges both batteries simultaneously.
