Fancy Buying 38Wh Spare 746641-001 Laptop Battery for HP OA04 OA03 740715-001 746458-421 751906-541 HSTNN-LB5Y HSTNN-LB5S OA04041 J1U99AA HSTNN-PB5Y TPN-F113 TPN-F115

product was a perfect fit. included tools I needed. arrived before del date. all great so far.

The battery won't charge. I tried all troubleshooting except resetting the bios. The company is sending a new one. Amazon won't take it back because they aren't able to take items that are hazardous. Now I get to find how to safely discard it. Update, I received a replacement battery for the one above. It looked like it wouldn't work BUT after much work with AI, I finally found out that Lenovo actually identifies battery 1 as internal and #2 as external. This is opposite the way from most batteries are identified

Battery arrived on time, was easy to install and solved my problem.

My laptop battery was running low so I replaced it it is easy to install, I watched some YouTube videos now I can use my laptop without it plugged in all the time

Stay away. This battery is a waste of time and money. Died abruptly during use prior to completing the break-in charging cycle. New replacement laptop battery (EV06047 / CPT-SG5). Installed in HP G60 running MX Linux. Laptop dies instantly (hard power-off, no shutdown) around 40–43% on battery. Runs normally on the AC adapter. Battery reports 100% health. Terminal diagnostics indicated defective pack or BMS. ## Steve@Linuxmx:~ $ upower -i $(upower -e | grep -i bat); echo '---'; acpi -V native-path: BAT0 vendor: CPT-SG5 model: EV06047 serial: 64892 power supply: yes updated: Sat 29 Aug 2026 08:45:55 PM MDT (11 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 21.1122 Wh energy-empty: 0 Wh energy-full: 48.84 Wh energy-full-design: 48.84 Wh energy-rate: 28.5429 W voltage: 11.497 V charge-cycles: N/A time to full: 58.3 minutes percentage: 43% capacity: 100% technology: lithium-ion icon-name: 'battery-good-charging-symbolic' History (charge): 1788057955 43.000 charging 1788057895 42.000 charging History (rate): 1788057955 28.543 charging 1788057925 27.116 charging 1788057895 25.689 charging 1788057865 23.691 charging Battery 0: Charging, 43%, charging at zero rate - will never fully charge.

Fit exactly as advertised and holds a charge well

Match descriptions and works great. Appears to be a stable quality battery after a weeks of use. Will order the interior battery from them now. Well package and fit properly.

Although my laptop was not listed for this battery, all the specific's matched what I needed for an Acer A515-54-51DJ. My laptop is back to being cordless again!
