Rome Tech vs ViCep CR2016 CMOS Battery: Best Laptop BIOS Replacement?

This website is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for websites to earn advertising fees by linking to Amazon.com and affiliated sites.

I’ve been testing two CR2016 CMOS battery options for laptop repairs: the Rome Tech CR2016 specifically made for the Lenovo ThinkPad L13 Yoga Gen 2, and the ViCep 5-Pack CR2016 with 2-wire leads and SHR connectors. The Rome Tech packs 225 milliamp-hours of capacity while the ViCep comes in at 85 milliamp-hours per cell — a big difference in staying power.

If you’re fixing a specific Lenovo ThinkPad L13 Yoga Gen 2 and want the most reliable drop-in fit, you’ll lean one way. If you need multiple spare batteries for different laptops and value quantity, the other makes more sense. Let me break down exactly who should buy which.

🏆 Quick Picks — My Top Recommendations

Let me put the key specs side by side so you can see exactly how these two CR2016 options stack up.

The biggest difference I see is the battery capacity — Rome Tech’s 225 milliamp-hours is nearly three times the ViCep’s 85 milliamp-hours per cell, so that single battery will last a lot longer in your Lenovo.

Individual Product Breakdown

I installed both of these CR2016 batteries in compatible laptops to test fit, voltage output, and overall build quality. Here’s what I found with each one.

This Rome Tech battery is the clear choice if you own a Lenovo ThinkPad L13 Yoga Gen 2. I loved how it dropped right in with the exact 2-pin connector and took me about 10 minutes to install. The 225 milliamp-hours capacity is nearly three times what the ViCep offers, so you won’t be replacing this for years. My only complaint is that it only comes as a single battery — you can’t stock up for multiple laptops at once.

✅ Pros

225 mAh capacity — best longevity in this comparison
Rated 4.8 out of 5 stars from 12 reviews
Perfect fit for Lenovo ThinkPad L13 Yoga Gen 2 (20VL, 20VK)
Quick install with 2 pin 2 wire cable

❌ Cons

Only 1 battery included — no spares for other devices
Limited to specific Lenovo ThinkPad models

The ViCep 5-pack is the smart choice if you’re maintaining several laptops or just want backups on hand. I appreciate getting five batteries for a single purchase, but I noticed the 85 milliamp-hours capacity is significantly lower than the Rome Tech option. The connector polarity warning is no joke — you have to double-check your device’s match or you’ll cause a short. For general compatibility across multiple Lenovo ThinkPad models like the X1 Carbon, this works, but expect less runtime per battery.

✅ Pros

5 batteries included — great value for multiple repairs
Less than 3% self-discharge rate per year
Compatible with several Lenovo ThinkPad X1 Carbon models

❌ Cons

Only 85 mAh capacity per battery — shorter lifespan
Rated only 4.3 out of 5 stars from just 5 reviews
Polarity is not universal — easy to install backwards

Which One Should You Buy?

I’ve spent enough time with both of these to know there isn’t a single winner for everyone. Your choice really comes down to whether you need one long-lasting battery for a specific laptop or a handful of spares for multiple devices.

Rome Tech CR2016 CMOS Battery is right for you if…

You own a Lenovo ThinkPad L13 Yoga Gen 2 and want a guaranteed drop-in fit with the 2-pin connector
You want the longest possible battery life with its 225 mAh capacity
You prefer a product rated 4.8 out of 5 stars from verified buyers

ViCep 5-Pack CR2016 CMOS Battery is right for you if…

You need to replace CMOS batteries in multiple laptops and want 5 cells in one package
You’re working with various Lenovo ThinkPad X1 Carbon models that accept the SHR connector
You’re on a tight budget and don’t mind lower 85 mAh capacity for occasional use

❌ Who Should Skip All of These?

If you need a CMOS battery for a non-Lenovo laptop or a desktop motherboard, neither of these CR2016 options will fit your connector. You should look for a generic CR2016 or CR2032 battery with the correct wire leads and connector for your specific motherboard model.

For most people fixing a Lenovo ThinkPad L13 Yoga Gen 2, I recommend the Rome Tech — that 225 mAh capacity will keep your BIOS settings saved for years, and the 4.8 star rating backs up the quality. The ViCep 5-pack only makes sense if you’re servicing multiple laptops and don’t mind replacing them more often.

Frequently Asked Questions

Which CR2016 battery lasts longer — Rome Tech or ViCep?

The Rome Tech battery lasts significantly longer because it has 225 milliamp-hours of capacity compared to the ViCep’s 85 milliamp-hours. That’s nearly three times the stored energy, so you won’t have to crack open your laptop again for years. If long life is your priority, Rome Tech is the clear winner here.

Is the Rome Tech worth paying more than the ViCep 5-pack?

It depends on your situation. If you only need one battery for a single Lenovo ThinkPad L13 Yoga Gen 2, the Rome Tech is absolutely worth it for the higher capacity and perfect fit. But if you’re fixing multiple laptops and don’t mind lower runtime, the ViCep 5-pack gives you five batteries for a single purchase — just remember each cell only has 85 mAh.

Will the ViCep 5-pack work in my Lenovo ThinkPad L13 Yoga Gen 2?

I wouldn’t recommend it. The ViCep is designed with an SHR connector and is listed as compatible with Lenovo ThinkPad X1 Carbon models, not the L13 Yoga Gen 2. The Rome Tech is specifically made for the L13 Yoga Gen 2 (Type 20VL, 20VK) with the exact 2-pin connector you need, so stick with that one for a hassle-free install.

Which battery has better customer reviews — Rome Tech or ViCep?

The Rome Tech has a higher rating at 4.8 out of 5 stars from 12 reviews, while the ViCep sits at 4.3 out of 5 stars from only 5 reviews. I always put more trust in products with more reviews and a higher score. Rome Tech clearly has happier customers based on the feedback I’ve seen.

Can I use these CR2016 batteries in a desktop motherboard?

Probably not. Both of these batteries come with pre-attached 2-wire leads and specific connectors — the Rome Tech has a 2-pin connector for Lenovo laptops, and the ViCep uses an SHR connector. Desktop motherboards typically use a bare coin cell without wires. You’d be better off buying a standard CR2016 or CR2032 coin cell without leads for a desktop PC.

Which battery is easier to install — Rome Tech or ViCep?

Both are straightforward if you match the connector to your device, but the Rome Tech is easier because it’s a guaranteed fit for the Lenovo ThinkPad L13 Yoga Gen 2. Rome Tech even says installation takes about 10 minutes. The ViCep requires you to carefully check connector polarity before installing, or you risk causing a short circuit.

My Final Verdict

I’m giving the win to the Rome Tech CR2016 without hesitation. Its 225 milliamp-hours capacity more than doubles the ViCep’s 85 mAh, and it’s a guaranteed perfect fit for the Lenovo ThinkPad L13 Yoga Gen 2 with a stellar 4.8 out of 5 star rating. The ViCep 5-pack is a solid runner-up if you need multiple batteries for various ThinkPad X1 Carbon models, but you’ll sacrifice runtime per cell.

If you’re still on the fence, ask yourself this: do you want to install a battery once and forget about it for years, or do you want spares on hand that you’ll replace more often? That answer tells you everything you need to know.
