A TON more power and battery life, very sug and secure fit, recharges with the Milwaukee charger that comes with the drill / driver combo kit, and (this is my favorite part) my 18v tools still fit in the case with these larger batteries attached. Great work designing an affordable and quality product. Review: Total junk - These are a complete waste of money. I ordered two the two pack on May 1st, and received them in a timely manner. Both batteries appeared to work and charge the same as my other Milwaukee batteries at first. Within a couple weeks, one battery malfunctioned, and the lights never turned off. Normally the lights turn on when you push the button, or are on the charger. The lights never turn off no matter what you do. The battery was still "operable", but I feared there was something wrong internally, so I contacted the seller. The seller was quick to reply, and asked for a video of the battery with the problem. I made a video, and provided it to them, and they sent out a 9.0Ah battery as a replacement for the 5.0Ah battery with the malfunction. When I went to use the second battery last week, it was completely dead. No lights would turn on. I have had Milwaukee batteries for 10 years, and have never had a battery that has never had the lights not turn on. I figured it static discharged to zero, and just needed a charge. I placed it on the charger and the red and green lights both flashed, indicating there is a battery malfunction. I have two chargers, and got the same result on both chargers. so within two months, both original batteries have malfunctioned. I made another video and contacted the seller. I was advised they would only refund half of the purchase price since they sent out the 9.0AH battery that has the same value as two 5,0Ah batteries, and I could buy two more batteries with the money they refunded me. I am reluctant to spend any more money on these batteries since both 5.0 batteries failed within two months, and I haven't had the 9.0 battery longer than two weeks to see if it will even make it that long. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HP9LUIO | | Amperage | 5 Amps | | Antenna Location | Power Tool | | Battery Capacity | 5 Amp Hours | | Battery Cell Composition | Sealed Lead Acid | | Battery Cell Type | Sealed Lead Acid | | Brand | GERIT BATT | | Customer Reviews | 3.4 out of 5 stars 337 Reviews | | Item Dimensions | 3.9 x 3.1 x 3.5 inches | | Item Weight | 1.3 Pounds | | Manufacturer | GERIT BATT | | Model Name | Milwaukee M18 | | Model Number | M18 | | Number of Batteries | 2 A batteries required.

I bought the two pack one for me and one for the guy that works in the bay next to me, we are both mechanics and we use our M18 1/2 drive imoact guns all day on anything from lug nuts to suspension parts to motor mounts and these batteries just don't quit. I can get almost a day and a half out of a full charge. Battery fits pretty tight but I actually like it better since my Milwaukee battery has gotten so loose I lose connection occasionally. I waited a solid month to leave this review, I'm confident now these are good and I will be buying another set. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/31352206-18v-5-0ah-replace-for-milwaukee-m18-battery-m18b-48](https://www.desertcart.co.uk/products/31352206-18v-5-0ah-replace-for-milwaukee-m18-battery-m18b-48) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-15*
