Bosch New 36V Charger AL36V-20 36V Rotak Lawnmower Charger Replaces AL3620CV (3H)

Bosch New 36V Charger AL36V-20 36V Rotak Lawnmower Charger Replaces AL3620CV (3H)

Q: Will this charger work with the 6 AH battery?

My charger originally came with the mower and a 2A battery. My charger is rated at 2A DC and has the same model number without the 3H on the end. I don’t have any issues charging this battery. I am not sure what 3H stands for. I don’t believe you would have any problems as even a 1A output would eventually charge the battery. Just would need more time. If the 3H refers to 3A output that would be a faster charge than the one I have. My best guess is it should be fine. Hope this helps.

Q: What size of charger will fit my lawn mower 36volt high power battery as charger i bought was too small

Hello, Thank you for the query. Our 36V batteries can be charged by any of our 36V chargers. The most common of these is the AL 3620 CV from this listing or the equivalent AL 36V-20. Best regards, Robert Bosch Power Tools

Q: i have a bosch 36v charger that has stopped working the model number is al 3640cv will a al3620cv work in its place as i'm unable to find a al3640cv

I believe the 40 means it is a 4 amp charger 36 volts so 3640 whereas 20 means a 2 amp charger, 36 volts, hence 3620, so a slower charge.

Q: Need a replacement charger for Bosch 36v sds is this suitable..?

I use it to charge 36v 2.6Ah Bosch part number 2 607 336 633.

Excellent product

This was bought to replace an old charger that failed. Not had it long but it says it is a fast charger and it is. It fully charged my Bosch Lion battery in 2 hours much faster than the old one. Brilliant

Other customers feedback helped me.

Similar to some other customers, I was looking for a charger to replace the one for my Bosch lawn mower which had 'blown'. I spent too long looking for a charger that looked the same or similar to my old one by comparing the connector 'pins' etc. The old one had 4 but all the replacement chargers for a 36V battery online had only 3. Thankfully, I read some reviews from other customers & found that the 3 pin replacement charger would fit my old 4 pin battery & therefore ordered one at a very reasonable price of £34. It works! Very pleased & great value for money.
