If you’re hunting for a CR2016 CMOS battery for your HP ProBook, you’ve probably landed on two solid options: the ViCep 5-Pack and the Rome Tech single battery. The ViCep gives you five batteries with an 85 mAh capacity each, while the Rome Tech packs a bigger 225 mAh punch but only comes as a single unit.
This comparison is for anyone fixing up an HP ProBook 450 G6, G7, or 440 G7 who wants a reliable backup BIOS battery without wasting money. I’ll break down which one gives you the best bang for your buck and which one is actually easier to install.

Individual Product Breakdown
I tested both of these CR2016 CMOS batteries in my own HP ProBook to see which one actually saves your BIOS settings and which one gives you the best long-term value. Here is what I found with each.
ViCep 5-Pack CR2016 CMOS Battery 3V Motherboard BIOS Batteries
5 Batteries | 85 mAh each | SHR Connector | 2 Wire Leads
- 1.Product Specifications--Model: CR2016; Connector: SHR02. Make Sure Device...
- 2.Long-Lasting Power & Reliable Performance--Less than 3% self-discharge...
The ViCep 5-Pack is my top pick because you get five batteries for the price of one from the competition. Each battery has an 85 mAh capacity and a very low self-discharge rate of less than 3% per year, which means they will hold their charge while sitting in your drawer. I really like that it includes an SHR connector with 2 wire leads, but you absolutely need to double-check your device’s polarity before installing. This pack is perfect if you own multiple laptops or want a spare on hand for the future, though the single-battery capacity is lower than the Rome Tech.
✅ Pros
- You get 5 batteries in one pack, great value for multiple laptops
- Self-discharge rate is under 3% per year
- Rated 4.3 out of 5 stars from customers
- Anti-leak technology and corrosion-resistant construction
❌ Cons
- Only 85 mAh capacity per battery, lower than some single options
- Polarity is not universal, so you must verify it matches your device
- Not specifically listed for HP ProBook models
Rome Tech CR2016 CMOS BIOS Battery for HP ProBook 450 G6
1 Battery | 225 mAh | 2 Wire Cable | Fits 450 G6, G7, 440 G7
- Rome Tech 840 G6 BIOS battery CR2016 best suits to replace your broken or...
- RTC battery compatible with such models as: HP ProBook 450 G6, HP ProBook...
The Rome Tech CR2016 is my runner-up because it is specifically designed for HP ProBook 450 G6, G7, and 440 G7 laptops, so you know the fit and connector will be right. The standout spec here is the 225 mAh capacity, which is nearly three times the per-battery capacity of the ViCep pack, meaning it should last much longer once installed. I appreciate that Rome Tech claims installation takes only about 10 minutes, but the single battery count and lower 3.6-star rating from 13 reviews hold it back. This is the one to get if you just need a single, high-capacity battery for one specific HP ProBook and want a guaranteed fit.
✅ Pros
- High 225 mAh capacity per battery, much longer run time
- Specifically designed for HP ProBook 450 G6, G7, and 440 G7
- Quick 10-minute installation
❌ Cons
- Only 1 battery included, less value than the 5-pack
- Lower customer rating at 3.6 out of 5 stars from 13 reviews
- Alkaline cell composition, not lithium as many expect
Which One Should You Buy?
I’ve spent a lot of time looking at these two options, and the truth is the right pick comes down to whether you need spares or maximum longevity. Let me break down exactly who should grab which battery.
ViCep 5-Pack CR2016 CMOS Battery is right for you if…
- You own multiple HP ProBooks or other laptops and want a spare battery for each one since you get 5 batteries in the pack
- You want to keep a backup in your drawer for years thanks to the less than 3% self-discharge rate per year
- You are on a tighter budget and prefer the best value over the highest single-battery capacity
Rome Tech CR2016 CMOS BIOS Battery for HP ProBook 450 G6 is right for you if…
- You own a specific HP ProBook 450 G6, G7, or 440 G7 and want a guaranteed fit without checking polarity
- You want the longest possible battery life from a single cell thanks to the 225 mAh capacity
- You only need to replace one battery and don’t care about having spares
❌ Who Should Skip All of These?
If your HP ProBook uses a different connector type, like a 4-pin or JST connector, neither of these CR2016 batteries with a 2-wire lead will work. You should also skip these if you need a CR2032 battery instead, as that has a different thickness and capacity entirely.
For the most common buyer who just needs to fix a single HP ProBook 450 G6, I’d grab the Rome Tech for its guaranteed fit and high 225 mAh capacity. If you want the best value and a spare for later, the ViCep 5-Pack is the clear winner.
Frequently Asked Questions
Which is better for an HP ProBook 450 G6: the ViCep 5-pack or the Rome Tech single battery?
For a single HP ProBook 450 G6, I think the Rome Tech is the better choice because it’s specifically designed for that model. You get a guaranteed fit and a much higher 225 mAh capacity compared to the ViCep’s 85 mAh per battery. The ViCep is better only if you have multiple laptops to fix or want spares on hand.
Is the Rome Tech CR2016 worth the extra money over the ViCep 5-pack?
That depends entirely on what you need. The Rome Tech gives you nearly triple the battery capacity at 225 mAh versus 85 mAh, so it will last much longer before needing replacement. But the ViCep 5-pack gives you five batteries total, so if you factor in the cost per battery, the ViCep is the better deal for most people.
Can I use the ViCep 5-pack CR2016 in my HP ProBook 440 G7?
The ViCep is not specifically listed for the HP ProBook 440 G7, but it could work if the connector polarity matches your device. ViCep even warns that the connector polarity is not universal and will cause a shortage if it doesn’t match. I’d personally go with the Rome Tech for the 440 G7 since it’s explicitly listed as compatible.
Which battery has a higher capacity: the ViCep or the Rome Tech CR2016?
The Rome Tech wins this category hands down with a 225 mAh capacity per battery. The ViCep only offers 85 mAh per battery, which is roughly a third of the Rome Tech’s capacity. If you want a battery that will hold your BIOS settings for the longest time possible, the Rome Tech is the clear choice.
How long do these CR2016 CMOS batteries typically last in an HP ProBook?
The ViCep has a self-discharge rate of less than 3% per year, which is solid for storage, but in-use lifespan depends on your laptop. With the Rome Tech’s 225 mAh capacity, I’d expect it to last several years in a typical HP ProBook before needing replacement. The ViCep’s 85 mAh capacity will likely need replacing sooner under the same usage conditions.
Which battery is easier to install: the ViCep or the Rome Tech?
Rome Tech specifically says their battery takes about 10 minutes to install, which suggests a straightforward process for the HP ProBook. The ViCep doesn’t give an installation time, and you have to be extra careful about checking polarity since it’s not universal. I’d say the Rome Tech is easier if you have a compatible HP ProBook model, while the ViCep requires more caution.
My Final Verdict
After comparing these two CR2016 CMOS battery options, my clear winner is the ViCep 5-Pack. It gives you five batteries with an 85 mAh capacity each, a less than 3% self-discharge rate, and a much better value if you need spares or work on multiple laptops. The Rome Tech is the runner-up and best for someone with a single HP ProBook 450 G6 who wants a guaranteed fit and the higher 225 mAh capacity per cell.
If you’re still on the fence, ask yourself one question: do you need one battery now, or do you want backups for later? If the answer is backups, go with the ViCep 5-pack. If you want a single, high-capacity battery that is guaranteed to fit your HP ProBook, grab the Rome Tech.
