By the way, the LST136 is a discontinued model, while the LST140C is a current model...I think it just came out this year.They both have the same autofeed, and use the same spool, and of course, the same size line. The LST136 will pull 40v at max power, and 36v at normal/lower power...I noticed that someone has claimed that the LST140C is just on/off, but pages six and twelve of the manual says it's a variable speed control. I experimented a little, and it appears that the trigger's range of motion between off and full power is very, very short, as opposed to the LST136 (I really hate the bastard who stole mine--I'd either have to spend a lot more, or travel to another city to get another). I just now checked the B&D website to see what they say, and the LST136 is supposed to spin at 6500-8500 rpm, while the LST140C is supposed to be just 6500 rpm. Either their manual is wrong, or their website...take your pick.The LST136 uses the LBXR36 battery pack, and the LST140C uses the LBX1540...but aside from minor style differences (including rubber on the bottom of the LBXR36), and the LBX1540 having a three level charge indicator vs. the four that the LBXR36 has, they are identical, including charge/use time. They are interchangable, which is the very first thing I tried out, once I'd put my 140C together. By the way, that battery has been off the charger for about a year, give or take a few months, and it appears to still have a full charge on it...awesome!My LST136 came with the fast charger, and the LST140C I just bought came with a slow charger, which is likely part of why the LST140C is cheaper. The fast charger is a lot bigger...the battery fits into it, while the slow charger is a little thing that clips onto the terminals.On the LST140C, the plastic runs around a foot further down the shaft, with the handle snapping onto a pair of spring-loaded buttons, one of which has indentations which lock the position of the handle...a great improvement over the handle design of the LST136. The handle on the LST136, if I recall correctly, can be moved up and down the shaft, and can easily be accidentally turned out of line with the control switch, which isn't all that helpful. Also, the LST140C's length adjustment is mounted on the lower end of the plastic, as opposed to being somewhere between the handle and the head.If there is any difference between in the head/guard, it isn't much at all.I wish the LST140C's switch had a bit more play, but I suspect it won't really matter overall. **Q: Does this one come with the high speed charger? or the regular one? how long does it take to charge?** A: Regular charger I believe. For me it seems to take about three hours to recharge. I have two because I also bought a hedge trimmer. They seem to last about 25 minutes each, which is more than I can last. **Q: Do you have to stop every 5 minutes and re-adjust the line feed on this model?** A: yes - my LST136 will not autofeed with the newer slightly different version of AF100 spools that lack the chamfered spindle hole, old 18v model still autofeeds a champ with same spools **Q: Hello, is this the 20v or 40v battery? I only ask because others are saying 20v:/** A: My trimmer came with a 40V battery. I also bought the extra 2.5 ah 40V battery and 3 spools of line. I'm very happy with the purchase. --- ## 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.com.sa/products/40861376-40v-max-13-inch-string-trimmer-and-lawn-edger-battery](https://www.desertcart.com.sa/products/40861376-40v-max-13-inch-string-trimmer-and-lawn-edger-battery) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-08-14*
