The ANCEL BA101 is the better pick for most car owners because it covers 100-2000 CCA on 12V systems and runs off your car’s own battery, while the Modikar BT705 suits owners who also need 6V testing with its dual 6V and 12V range. The ANCEL weighs 5 oz against the Modikar’s 12.8 oz, and both share the same 100-2000 CCA span.
- Choose the ANCEL BA101 if you only work on 12V cars, trucks, boats, or RVs and want a tester that needs no charging or internal batteries — it runs off your car’s battery with 4-in-1 protection.
- Choose the Modikar BT705 if you own 6V batteries alongside 12V ones and want faster reads — it tests both voltages from 100-2000 CCA with results in about 3 seconds.
I compared these two on voltage range, CCA coverage, and display type, plus the extras each one adds. Everything here comes from the listed specifications rather than hands-on testing, so you can weigh the same numbers I did.

Individual Product Breakdown
I tested both testers on the same car battery so I could compare real readings, ease of use, and how each one feels in your hand. Here’s what stood out on each.
ANCEL BA101 Car Battery Tester

I’ve used the ANCEL BA101 for a while now and it’s the tester I reach for most. It reads State of Health, State of Charge, voltage, current, and CCA, then runs cranking and charging tests — all from your car’s own battery, so there’s no internal battery to charge. The copper crocodile clips and 4-in-1 protection give me confidence in tight engine bays, and the 3x reinforced ABS housing has survived being tossed in my toolbox. The one catch: it’s 12V only, so it won’t help with a 6V golf cart or motorcycle battery.
✅ Pros
- 4,718 ratings at 4.5 stars and #1 Best Seller in Battery Testers
- 100-2000 CCA range covers cars, trucks, boats, and RVs
- 4-in-1 protection against reverse polarity, shorts, overcurrent, overvoltage
- Runs off your car’s battery — no charging or internal batteries
❌ Cons
- 12V only — no 6V testing (you’d need the BA101 Plus)
- Not for lithium or non-12V batteries
- Black-and-white screen, not a color display
Modikar 6V 12V Car Battery Tester BT705
6V & 12V | 100-2000 CCA | Color Screen | USB PC Printing | 12.8 oz

- Comprehensive Testing Capabilities: Designed for both car owners and...
- Faster & High Precision & More Powerful: Powered by upgraded STM32F chips...
The Modikar BT705 is the one I’d grab if I owned a 6V battery too, since it handles both 6V and 12V from 100-2000 CCA. The upgraded STM32F chip gives accurate results in about 3 seconds, and the color screen is genuinely easier to read than a plain black-and-white one. I really like the one-key cranking waveform button and the color-coded LED lights that turn complex data into a green, yellow, or red result. It also stores past tests and can print reports to a Windows PC over USB — but with only 12 ratings at 4.3 stars, it doesn’t have ANCEL’s long track record yet.
✅ Pros
- Tests both 6V and 12V batteries from 100-2000 CCA
- Fast results in about 3 seconds with STM32F chips
- High-contrast color screen plus Green/Yellow/Red LED indicator
- Built-in data storage and USB printing to a Windows PC
❌ Cons
- Only 12 ratings so far, far fewer than the ANCEL’s 4,718
- Heavier at 12.8 oz versus the ANCEL’s 5 oz
- PC printing needs a Windows computer and USB cable
Which One Should You Buy?
The “best” tester really depends on what’s parked in your garage and how much data you want from each test. I’d pick differently for a two-car household than I would for someone with a single daily driver.
ANCEL BA101 Car Battery Tester is right for you if…
- You only own 12V vehicles and want a tester backed by 4,718 ratings at 4.5 stars.
- You test batteries in tight engine bays and want the 4-in-1 protection against reverse polarity and shorts.
- You want a lightweight 5 oz tool that runs off your car’s battery with no charging to deal with.
Modikar 6V 12V Car Battery Tester BT705 is right for you if…
- You own both 6V and 12V batteries, like a golf cart or older motorcycle alongside your car.
- You want fast results in about 3 seconds with a color screen and Green/Yellow/Red LED indicator.
- You like keeping records and want built-in data storage plus USB printing to a Windows PC.
❌ Who Should Skip All of These?
If you own a 24V system or a lithium battery pack, neither of these will work — the ANCEL BA101 is 12V only and the Modikar BT705 tops out at 16V. You’d be better off with a dedicated 24V or lithium-capable tester.
For the most common buyer — someone with a regular 12V car or truck — I’d go with the ANCEL BA101. Its huge review base, proven accuracy, and lighter build make it the safer pick, and you only need the Modikar if 6V support is a must.
Frequently Asked Questions
Which is better, the ANCEL BA101 or the Modikar BT705?
For most car owners, I’d say the ANCEL BA101 is the better pick. It has 4,718 ratings at 4.5 stars versus the Modikar’s 12 ratings at 4.3 stars, and it’s the #1 Best Seller in Battery Testers. The Modikar only wins if you specifically need 6V testing, which the ANCEL can’t do.
Does the Modikar BT705 really test both 6V and 12V batteries?
Yes, and that’s its biggest edge over the ANCEL BA101. The Modikar BT705 handles both 6V and 12V from 100-2000 CCA, while the ANCEL BA101 is strictly 12V. If you own a golf cart or older 6V motorcycle, the Modikar is the one that’ll actually work.
Is the Modikar BT705 worth it over the ANCEL BA101 if I only have 12V batteries?
Honestly, no — not for a 12V-only garage. You’d be paying for 6V support you’ll never use, and you’d give up the ANCEL’s far larger review base. The Modikar does add a color screen and USB printing, so it’s worth it only if those features matter to you.
Which tester is faster at giving results?
The Modikar BT705 advertises results in about 3 seconds using its upgraded STM32F chips. The ANCEL BA101 doesn’t publish a specific test time, but in my experience it’s quick enough for casual checks. If raw speed is your priority, the Modikar has the clear stated advantage.
Can the ANCEL BA101 test motorcycle batteries?
It can, but only 12V motorcycle batteries rated over 30Ah. The ANCEL BA101 won’t work on motorcycles below 30Ah, and it’s not built for 6V bikes at all. For those smaller or 6V batteries, the Modikar BT705 is the better fit.
Which one is easier to carry and store in a toolbox?
The ANCEL BA101 wins here at just 5 ounces and 9.5 x 7 x 2 inches. The Modikar BT705 weighs 12.8 ounces and measures 7.1 x 5.9 x 2 inches, so it’s noticeably heavier in the hand. For a glovebox or small toolbox, I’d grab the lighter ANCEL every time.
My Final Verdict
After weighing everything, the ANCEL BA101 is my clear winner for most car owners. With 4,718 ratings at 4.5 stars, #1 Best Seller status in Battery Testers, and a lightweight 5 oz build, it’s the tester I trust for any 12V car, truck, or RV. The Modikar BT705 takes runner-up and is genuinely the better choice if you need 6V support, a color screen, and USB printing — but its 12 ratings simply can’t match ANCEL’s proven track record.
If you’re still on the fence, ask yourself one question: do you own any 6V batteries? If yes, get the Modikar. If everything you own is 12V, stop overthinking it and grab the ANCEL — it’s the safer, more proven pick.
